Great video. Have you ever considered adding more aeration to offset the kh/ph effects from nitrification? Aeration will cause CO2 to outgas and raise pH naturally as a result without affecting kH. A lower kH coupled with an adjustable amount of aeration might be a viable option to stabilize the pH more, but at the same time more air will also equate to more nitrification, so it may take some experimentation to find the right balance.
@DZ7IC22 Thanks for the comment! That's a really interesting idea that's worth experimenting with. I'd love to test out different filters/methods and see what keeps pH the most stable, like a standard sponge filter vs asian-style UGF vs canister filter or something. From my understanding, the main pH swing that happens throughout the day is from plant photosynthesis. I'm not sure how much is from nitrification but it would be interesting to try to figure out. I'd also kind of think that a sponge filter would provide plenty of aeration but it's possible an additional air stone could help a lot. Keep those thoughts coming so we can push the hobby forward!
It's amazing that nature uses simple such simple mechanisms to accomplish things. I never knew that oxygen is transferred by a molecule that changes behavior in different pH. Is that how our blood works too?
@mrkshply Yep, exactly! Hemoglobin is the molecule in a human body that captures oxygen and delivers it where it needs to go. It works just like hemocyanin in an insects body. It's pretty amazing that such simple mechanisms of concentration gradients and pH can create incredibly complex organisms. Thanks for watching and appreciating the science :D

Love your channel! Learned a lot of things which I thought I knew! Any chance you can do a video on dwarf blue crayfish and how to keep their coloration blue? I read low PH but ... even with buffering soil and low ph mine stay brown / 1 or 2 are a deep blue. Having a hard time finding information on this!
@canadashrimps Thanks for the kind words! We've mostly dealt with neocaridina and caridina so don't have enough experience with dwarf blue crayfish to provide good information on them right now. This has been added to a list of video ideas for the future though, because we'd love to learn about them! Thanks for the suggestion and happy shrimpin' :D
This is interesting. I have had issues with ph swings in the past due to a very low kh in my water. Which would cause my ph to crash a ridiculous amount 3 or 4 days after a water change. I thought it was the drift wood. So I removed that. Waited a month and tested weekly. It was still happening. I have an overstocked tank with goldfish, so nitrate does fluctuate naturally for me. I added a large airstone to my aquarium and did a water change. A week after I tested my water. My ph stayed stable at about 7.0 and my KH stayed stable as well. I was even more shocked to see that my Nitrate was only at 25 ppm after a week! It's usually at 50 ppm I thought this was just a coincidence but now after watching this video, I think not.... 🤔 I love these types of videos. Informational and entertaining.
@ellaaqua Oxygen can certainly help prevent your pH from dropping by reacting with CO2 that your fish are breathing out, which would prevent KH from dropping as well. Would you be open to explaining your theory about why nitrates stayed lower? Maybe I'm forgetting something but I don't remember the video discussing a relationship between nitrates and pH/KH.
@shrimplyexplained I think they stayed lower because there was more flow in my tank after adding the airstone. Which allowed the filters to do their jobs more efficiently. I also change or rinse out the filter floss from my hang on back filter every 3 to 4 days. So my thoughts are that in my case, not only did increasing water circulation increase the efficiency of my filters. It also helped to stabilize my ph and kh. It could have been that there was too much waste accumulation in my tank that was causing the crashes in ph and kh. Or it could have been low oxygenation. I should add that I use a buffer to try and control my kh and ph but did not have much luck with until I added the airstone. I believe the oxygenation may have been what helped because I have a fairly deep tank at about roughly 24 inches.
@attiliodariva5417 Thanks for the feedback! It's really appreciated and something I'm happy to take out considering how much time it would save during editing :D
Heard a lot claim cannot use active substrates for neocaridina shrimp as it lower the PH , is more for caridina shrimp. Let's say I already put active substrates and rear neocaridina shrimp possible? I do see some shrimp keepers do a test using active substrates mean for caridina shrimp for neocardina shrimp also ok. Some even claim benefit more for neocardina to breed?
@retroworldnews That's kind of what this video was intended to combat. Most of the arguments I've heard against active substrate in neo tanks is that they need KH to make their shells so the low KH environment isn't good for them. In reality, carbonate will form in their bodies regardless of the environmental pH so that is not a limiting factor. I don't know about active substrate being any better or worse for neos. I've kept quite a few neo tanks with active substrate (fluval stratum) and they seem very happy. There's not great data on how they survive at lower pH ranges so, if your substrate brings the pH below 6, then I'd suggest using some crushed coral or baking soda to bring it up. Crushed coral is nice because it dissolves slowly over time and continues to combat the active substrate, whereas you'll have to add baking soda more frequently. Both can work when added in controlled amounts though. Lmk if you have any questions! May I ask what active substrate you're using?
I’m changing my water to salty shrimp now and I tested the gh and kh the gh is the same as my tank but the kh is a bit lower with the salty shrimp I was a bit worried about it until I watched this video
@user-ef6cm7vu4m yep, no reason to worry! The KH should be right around half the GH, unless you have an active substrate bringing down the pH/KH. If your substrate is inert, then a KH of at least 3-4 is a good idea, though you could probably get away with 2.
Thanks. I use sand I was a bit worried at first because my tap water kh was slightly higher than the salty shrimp when mixed to 250 tds I drained about 10% and got the new water dripping in very slowly
@alexchan4037 Sorry for the late reply! How the KH affects your animals depends on the type of substrate you have. Do you have active substrate like fluval stratum? If so, then the pH buffering ability of KH is replaced by the buffering ability of the substrate - at least until the substrate runs out. If you don't have a buffering substrate, then your tank is at risk of pH swings and possibly crashes that could be harmful to your inhabitants. Here's more information, along with various ways to change your KH: www.shrimplyexplained.com/the-shrimp-school/sb-103-basics-ph-kh-aquarium/
My ph is 8 or 8.2. I have liquid rock essentially also. Evaporation always leaves a thick white crust on the glass thats super hard to get off. I havent been able to keep shrimp alive except for a couple amano shrimp. I had my water tested and was told my ph is too high and i need almond leaves or driftwood to make my water be able to handle shrimp. Does that sound like an accurate assesment to you? Not really sure what else to use for a clean up crew. I have too many snails as it is.
@brixen0623 Thanks for the question! We'll see what we can do to help. I've heard of shrimp like neocaridina thriving in 8-8.2 pH so that's not necessarily the problem here. It does sound like you've got some pretty hard water based on the thick white crust left behind though. Do you know what your GH and KH are? It's likely that GH may need to be brought down, in which case almond leaves and driftwood only have a small effect. They do bring down KH but don't have a significant effect on the overall mineral content of your water (GH). It's also possible that your GH is made of mostly magnesium or mostly calcium, whereas shrimp need the right balance of those to molt properly. What shrimp did you try to keep previously? Did you notice if any of them had the "white ring of death" (look up pics on google if unsure)?
@shrimplyexplained I live in a watershed comprised mostly of limestone bedrock. Our water is thick with it so i would assume mostly calcium if thats the case. I've only used the api test straps to measure it and the GH and the KH come back as around 180ppm for kh and gh both. I did order some Indian almond leaves but they haven't arrived yet. We've tried cherries, amano and ghost shrimp. All of the cherry's got the white ring. Ghosts probably did also but they were in my sons tank and I admittedly didn't pay enough attention. 2 amano shrimp that snuck in with them seemed to do alright though.
@@brixen0623 Gotcha - thanks for the info! The white ring is a good indicator. Overall, 180 ppm of GH is within the "recommended" range. The problem is that GH is a measure of both calcium and magnesium but it doesn't tell us what ratio they are in the water, so your tank could be in the right GH range but have an unhealthy ratio. Frustrating, I know. If the mineral ratio is the issue, then indian almond leaves and other botanicals won't be much help. I've linked a way to test the mineral ratio below but that's not necessary if you already know it's all calcium. In that case, you can use info from that link to help figure out dosing requirements to add some magnesium to your tank and improve the mineral ratio. The other option is to use RO/DI water with a remineralizer but that can be expensive. LMK if you have any questions! www.shrimplyexplained.com/tools/calcium-to-magnesium-ratio-calculator-shrimp-keepers/
@shrimplyexplained thank you very much. You've easily just became the most helpful RUclipsr I've found on the topic. I genuinely appreciate the help amd insight.
@@brixen0623 Thank you, hopefully the suggestions help! If you want to learn more about GH, this video may also be helpful: ruclips.net/video/-Igp6tTu8BM/видео.html Something you may be interested in hearing about is that I'm currently doing is testing the tolerable GH ranges for neocaridina. I have one tank at 2-3 dGH and one tank at 30+ dGH, both of which are way out of the "recommended" range. I'm using Salty Shrimp remineralizer to get the tanks to that range so the mineral ratios are still healthy and, guess what? the shrimp are still alive and well and breeding for the past two months. It's not a perfect test, but it's additional evidence to support the idea that mineral ratios matter much more than GH.
Hello sir, is it possible ammonification more than nitrification in an old tank, and make the pH go up? If it is, should I put nitrifying bacteria or EM into the tank regularly?
@yql7597 That's an interesting question! To be honest, I'm not entirely sure. According to this article in Nature (see below), ammonification releases hydrogen ions so that process should lower pH instead of raise it. Assuming your tank is cycled and the bioload doesn't change drastically, there should be enough nitrifying bacteria to handle any waste. It probably won't hurt to add more but shouldn't be necessary. Does that help? www.nature.com/scitable/knowledge/library/the-nitrogen-cycle-processes-players-and-human-15644632/#:~:text=%2C%20algal%20blooms).-,Ammonification,the%20process%20known%20as%20ammonification.
Hello sir, is it possible to buffer a water between KH1-3 and PH 6.5-7 ? I have my ro water(PH6.3) reminenraled to KH 1, but it also made PH up to 7. Should I put some acid in it?
@yql7597 You definitely can have water with the ranges you stated. A couple of questions: 1. What are you using to remineralize your RO water? 2. What substrate do you have? 3. What shrimp are in or expected to be in the tank?
@@shrimplyexplained I am keeping caridina mariae in my tank, using active soil and some little rocks. I remineralized my ro water using MgSO4, Calcium acetate, NaHCo3 and KHCo3. I tried to keep the KH 0-0.5, but I found the PH goes up and down in 1 day. I want the PH stable, so I am trying to make KH up to 1, but I don't want PH go up to 7+
@@shrimplyexplained I noticed pH swing 0.5 in one day. Recently I put more NaHCo3 and KHCo3 in the water, make the KH up to 1 and it doesn't swing so much, now the pH is around 6.8-7.2. But I was been told by some research caridina mariea like pH below 7.0. I am using Netlea active soil in my tank, and some little rocks
@@shrimpkeepermatt1989 Caridina marinae (tiger shrimp) are generally pretty hardy so it's possible 1 pH swing may not be a serious problem for them. If you have had them for a while and haven't seen them breed or haven't seen the babies survive though, then that could be a good indicator the pH swing is a problem. An active substrate is intended to keep the pH lower, but it depends on the quality and the batch and the age of the substrate. After consistent water changes for 8+ months the substrate could be depleted and no longer have the ability to lower pH as effectively. Another factor is plant density. A higher number of plants causes a larger pH swing throughout the day. It's generally very slow so is not particularly stressful, but removing some plants may be another option to mitigate pH swings. Lastly, it sounds like you're covering most of your bases with your custom remineralizer recipe, although there are some other minerals that may not be accounted for. Are you adding anything into the water to dose micronutrients like manganese?
@@paulm0573 Haha gotcha! To be clear, did you feel lost because: A. The explanation wasn't clear enough. B. The information didn't seem useful enough to watch further C. You aren't interested in the hobby at such a microscopic level I'm curious to understand if there's something I might be able to do to either clarify things more or if I needed to do a better job to explain WHY this information is important/useful. Appreciate any additional feedback :D
@@shrimplyexplained I wouldn't take that comment to heart. I imagine most of your viewers are literate enough to be fully captivated by the video, like me. This video was incredibly necessary, as most folks who keep shrimps are either doing it right, or killing shrimp and come here. If they are unable to digest this info, they shouldn't be keeping shrimp. The title of the video is "The Science of Stable Shrimp Tanks".
@@BlakeDonowitz-mk7iu Hey, thanks for the kind words, Blake! I appreciate you coming to our defense. Our videos are lucky enough to receive mostly supportive comments like yours. Negative comments may not feel great but it's also important to hear from those who don't like the videos if the feedback is constructive. If we get multiple of these comments saying the explanation was too confusing then that's a good indicator we need to improve our explanations. This initial comment probably could have been phrased differently but we still appreciate the commenter for taking the time to provide feedback. You're totally right that a lot of shrimp keepers would benefit from understanding the science of their tank better. Some people don't want to get into the nitty gritty details though, and we're not sure that's a sign of irresponsibility. Many hobbyists can likely get away with just understanding that KH limits pH swings so having some KH is good, and if you don't have much KH then you need another buffering source. We have to be careful about intellectually gatekeeping a hobby. For example, there are probably much more successful shrimp breeders out there who have much less knowledge of the science than even what the video goes over. They may understand the key information about KH in a different way and that's great, as long as they are focused on the health of their animals. We all enjoy our hobby in a different way and it's great that you like the science behind it! Happy shrimpin' :D

Would you be open to explaining your theory about why nitrates stayed lower? Maybe I'm forgetting something but I don't remember the video discussing a relationship between nitrates and pH/KH.
@shrimplyexplained I think they stayed lower because there was more flow in my tank after adding the airstone. Which allowed the filters to do their jobs more efficiently. I also change or rinse out the filter floss from my hang on back filter every 3 to 4 days. So my thoughts are that in my case, not only did increasing water circulation increase the efficiency of my filters. It also helped to stabilize my ph and kh. It could have been that there was too much waste accumulation in my tank that was causing the crashes in ph and kh. Or it could have been low oxygenation. I should add that I use a buffer to try and control my kh and ph but did not have much luck with until I added the airstone. I believe the oxygenation may have been what helped because I have a fairly deep tank at about roughly 24 inches.
Very helpful! Subbed
Great educatiional video.
Little constructive feedback: the chalk sound effect is very distracting.
@attiliodariva5417 Thanks for the feedback! It's really appreciated and something I'm happy to take out considering how much time it would save during editing :D
Great video, thanks!
@Wintersdark Glad you liked it! Did you feel the explanations all made sense or were there any parts that could have been more clear?
Heard a lot claim cannot use active substrates for neocaridina shrimp as it lower the PH , is more for caridina shrimp. Let's say I already put active substrates and rear neocaridina shrimp possible? I do see some shrimp keepers do a test using active substrates mean for caridina shrimp for neocardina shrimp also ok. Some even claim benefit more for neocardina to breed?
@retroworldnews That's kind of what this video was intended to combat. Most of the arguments I've heard against active substrate in neo tanks is that they need KH to make their shells so the low KH environment isn't good for them. In reality, carbonate will form in their bodies regardless of the environmental pH so that is not a limiting factor.
I don't know about active substrate being any better or worse for neos. I've kept quite a few neo tanks with active substrate (fluval stratum) and they seem very happy. There's not great data on how they survive at lower pH ranges so, if your substrate brings the pH below 6, then I'd suggest using some crushed coral or baking soda to bring it up. Crushed coral is nice because it dissolves slowly over time and continues to combat the active substrate, whereas you'll have to add baking soda more frequently. Both can work when added in controlled amounts though.
Lmk if you have any questions! May I ask what active substrate you're using?
@@shrimplyexplained I used one is all in japanese words I remember the package it stated lower PH and show is a caridina shrimp.
@@retroworldnews Ah okay. Does akadama sound right?
@@shrimplyexplained nope, I only remember the package showing caridina shrimp and I do remember the package highlight PH which show lower down.
I’m changing my water to salty shrimp now and I tested the gh and kh the gh is the same as my tank but the kh is a bit lower with the salty shrimp I was a bit worried about it until I watched this video
@user-ef6cm7vu4m yep, no reason to worry! The KH should be right around half the GH, unless you have an active substrate bringing down the pH/KH. If your substrate is inert, then a KH of at least 3-4 is a good idea, though you could probably get away with 2.
Thanks. I use sand I was a bit worried at first because my tap water kh was slightly higher than the salty shrimp when mixed to 250 tds I drained about 10% and got the new water dripping in very slowly
My new tank has very low KH like just 1, how is this going to affect my snail and shrimp? How to raise KH?
@alexchan4037 Sorry for the late reply! How the KH affects your animals depends on the type of substrate you have. Do you have active substrate like fluval stratum? If so, then the pH buffering ability of KH is replaced by the buffering ability of the substrate - at least until the substrate runs out. If you don't have a buffering substrate, then your tank is at risk of pH swings and possibly crashes that could be harmful to your inhabitants. Here's more information, along with various ways to change your KH: www.shrimplyexplained.com/the-shrimp-school/sb-103-basics-ph-kh-aquarium/
My ph is 8 or 8.2. I have liquid rock essentially also. Evaporation always leaves a thick white crust on the glass thats super hard to get off. I havent been able to keep shrimp alive except for a couple amano shrimp. I had my water tested and was told my ph is too high and i need almond leaves or driftwood to make my water be able to handle shrimp. Does that sound like an accurate assesment to you? Not really sure what else to use for a clean up crew. I have too many snails as it is.
@brixen0623 Thanks for the question! We'll see what we can do to help.
I've heard of shrimp like neocaridina thriving in 8-8.2 pH so that's not necessarily the problem here. It does sound like you've got some pretty hard water based on the thick white crust left behind though. Do you know what your GH and KH are?
It's likely that GH may need to be brought down, in which case almond leaves and driftwood only have a small effect. They do bring down KH but don't have a significant effect on the overall mineral content of your water (GH). It's also possible that your GH is made of mostly magnesium or mostly calcium, whereas shrimp need the right balance of those to molt properly. What shrimp did you try to keep previously? Did you notice if any of them had the "white ring of death" (look up pics on google if unsure)?
@shrimplyexplained I live in a watershed comprised mostly of limestone bedrock. Our water is thick with it so i would assume mostly calcium if thats the case. I've only used the api test straps to measure it and the GH and the KH come back as around 180ppm for kh and gh both. I did order some Indian almond leaves but they haven't arrived yet. We've tried cherries, amano and ghost shrimp. All of the cherry's got the white ring. Ghosts probably did also but they were in my sons tank and I admittedly didn't pay enough attention. 2 amano shrimp that snuck in with them seemed to do alright though.
@@brixen0623 Gotcha - thanks for the info! The white ring is a good indicator.
Overall, 180 ppm of GH is within the "recommended" range. The problem is that GH is a measure of both calcium and magnesium but it doesn't tell us what ratio they are in the water, so your tank could be in the right GH range but have an unhealthy ratio. Frustrating, I know.
If the mineral ratio is the issue, then indian almond leaves and other botanicals won't be much help.
I've linked a way to test the mineral ratio below but that's not necessary if you already know it's all calcium. In that case, you can use info from that link to help figure out dosing requirements to add some magnesium to your tank and improve the mineral ratio.
The other option is to use RO/DI water with a remineralizer but that can be expensive. LMK if you have any questions!

@shrimplyexplained thank you very much. You've easily just became the most helpful RUclipsr I've found on the topic. I genuinely appreciate the help amd insight.
@@brixen0623 Thank you, hopefully the suggestions help! If you want to learn more about GH, this video may also be helpful: ruclips.net/video/-Igp6tTu8BM/видео.html
Something you may be interested in hearing about is that I'm currently doing is testing the tolerable GH ranges for neocaridina. I have one tank at 2-3 dGH and one tank at 30+ dGH, both of which are way out of the "recommended" range. I'm using Salty Shrimp remineralizer to get the tanks to that range so the mineral ratios are still healthy and, guess what? the shrimp are still alive and well and breeding for the past two months. It's not a perfect test, but it's additional evidence to support the idea that mineral ratios matter much more than GH.
Hello sir, is it possible ammonification more than nitrification in an old tank, and make the pH go up? If it is, should I put nitrifying bacteria or EM into the tank regularly?
@yql7597 That's an interesting question! To be honest, I'm not entirely sure. According to this article in Nature (see below), ammonification releases hydrogen ions so that process should lower pH instead of raise it. Assuming your tank is cycled and the bioload doesn't change drastically, there should be enough nitrifying bacteria to handle any waste. It probably won't hurt to add more but shouldn't be necessary. Does that help?

Hello sir, is it possible to buffer a water between KH1-3 and PH 6.5-7 ? I have my ro water(PH6.3) reminenraled to KH 1, but it also made PH up to 7. Should I put some acid in it?
@yql7597 You definitely can have water with the ranges you stated. A couple of questions:
1. What are you using to remineralize your RO water?
2. What substrate do you have?
3. What shrimp are in or expected to be in the tank?
@@shrimplyexplained I am keeping caridina mariae in my tank, using active soil and some little rocks.
I remineralized my ro water using MgSO4, Calcium acetate, NaHCo3 and KHCo3.
I tried to keep the KH 0-0.5, but I found the PH goes up and down in 1 day. I want the PH stable, so I am trying to make KH up to 1, but I don't want PH go up to 7+
@@shrimpkeepermatt1989 How much of a pH swing are you seeing throughout the day at the current KH? Also, what active substrate are you using?
@@shrimplyexplained I noticed pH swing 0.5 in one day. Recently I put more NaHCo3 and KHCo3 in the water, make the KH up to 1 and it doesn't swing so much, now the pH is around 6.8-7.2. But I was been told by some research caridina mariea like pH below 7.0.
I am using Netlea active soil in my tank, and some little rocks
@@shrimpkeepermatt1989 Caridina marinae (tiger shrimp) are generally pretty hardy so it's possible 1 pH swing may not be a serious problem for them. If you have had them for a while and haven't seen them breed or haven't seen the babies survive though, then that could be a good indicator the pH swing is a problem.
An active substrate is intended to keep the pH lower, but it depends on the quality and the batch and the age of the substrate. After consistent water changes for 8+ months the substrate could be depleted and no longer have the ability to lower pH as effectively.
Another factor is plant density. A higher number of plants causes a larger pH swing throughout the day. It's generally very slow so is not particularly stressful, but removing some plants may be another option to mitigate pH swings.
Lastly, it sounds like you're covering most of your bases with your custom remineralizer recipe, although there are some other minerals that may not be accounted for. Are you adding anything into the water to dose micronutrients like manganese?
As long as your tank is stable most shrimps can thrive
Way too technical explanation for my liking and understanding
@paulm0573 Thanks for the feedback! That's really useful to know. At what point did the video lose you?
After the first few minutes when you went all scientific on us 😂
@@paulm0573 Haha gotcha! To be clear, did you feel lost because:
A. The explanation wasn't clear enough.
B. The information didn't seem useful enough to watch further
C. You aren't interested in the hobby at such a microscopic level
I'm curious to understand if there's something I might be able to do to either clarify things more or if I needed to do a better job to explain WHY this information is important/useful.
Appreciate any additional feedback :D
@@shrimplyexplained I wouldn't take that comment to heart. I imagine most of your viewers are literate enough to be fully captivated by the video, like me.
This video was incredibly necessary, as most folks who keep shrimps are either doing it right, or killing shrimp and come here.
If they are unable to digest this info, they shouldn't be keeping shrimp. The title of the video is "The Science of Stable Shrimp Tanks".
@@BlakeDonowitz-mk7iu Hey, thanks for the kind words, Blake! I appreciate you coming to our defense.
Our videos are lucky enough to receive mostly supportive comments like yours. Negative comments may not feel great but it's also important to hear from those who don't like the videos if the feedback is constructive. If we get multiple of these comments saying the explanation was too confusing then that's a good indicator we need to improve our explanations. This initial comment probably could have been phrased differently but we still appreciate the commenter for taking the time to provide feedback.
You're totally right that a lot of shrimp keepers would benefit from understanding the science of their tank better. Some people don't want to get into the nitty gritty details though, and we're not sure that's a sign of irresponsibility. Many hobbyists can likely get away with just understanding that KH limits pH swings so having some KH is good, and if you don't have much KH then you need another buffering source.
We have to be careful about intellectually gatekeeping a hobby. For example, there are probably much more successful shrimp breeders out there who have much less knowledge of the science than even what the video goes over. They may understand the key information about KH in a different way and that's great, as long as they are focused on the health of their animals. We all enjoy our hobby in a different way and it's great that you like the science behind it!
Happy shrimpin' :D
