thx but I understand nothing! :) My tank's water is PH: 7 / KH 6,5. I want to have a PH of 6,5. I just have to had Acid buffer until I have PH: 6,5 no? I understand that my KH will also drop with Acid Buffer, I just have to be careful and not drop under KH:4. If my KH go under 4 : I use Alkaline Buffer to raise it over 4? is that correct?
No, if you reach 6.5 at 2dkh the. Just keep it at 2dkh. Raising kh will raise the pH as well. Every aquarium is different and many things can effect ph beside kh
If you're using CO2 then keeping kh anywhere between 2-4 and still get 6.5 pH shouldn't be a problem as cow is acidic. Just pump more cow to lower the pH. As long as you keep the dissolve cow to below 40mg/l it will be safe for the fishes
Bro… Discus buffer and the acid puffer same ka? Also the usage also same, need to do together with alkaline buffer also ka? (Cause I’m not good at water chemistry.)
Discus buffer act differently then acid or alkaline buffer. Discus buffer will automatically raise or lower pH to 6.5. It is suitable for aquarium that have pH which is close to 6.5 as it is not as effective in altering pH as acid and alkaline buffer. Discus buffer also contain phosphorus which might cause algae to grow faster if use too frequently. Which is way for aquarium water. That have pH close to 6.5 using discus buffer is more easier. But if the water need to be redose daily to hold its pH then acid and alkaline buffer is more suitable.
150 Liters is between 30 and 40 gallons right? If i put 16 grams of buffer in my water wouldnt it be 500+ ppm? Im supposed to be between 200-250ppm right? When i adjust my kh i use like 3 grams of buffer total and then remineralize with with a couple grams of equalibrium and a couple ML's of replenish. All seachem products and the tds in my water is between 200 and 250 ppm. Am i doing it all wrong? Do i want my ppms to be over 250 or even 500+? Im confused..
Hi before I can answer, could you let me know what are you referring to when you mentioned 500+ppm? 500+ppm of carbonate in water? Cause that can't be right. And also why are you using both replenish and equilibrium?
@SeachemMalaysia well from what I've learned through various videos my tds should be around 200 ppm tds with kh and gh. Why I use equalibrium and replenish is cause I was thinking maybe one had minerals that the other wouldn't have. Not sure, I'd like to figure it out.. I'm growing live plants. I've been using like 1.3 grams of acid and 1.7 or alkaline but I've probably been doing it wrong.. fish seem to do ok and I haven't had to do many water changes but most plants don't grow very fast
TDS is for Total Dissolved Solids. Which mean it measure anything that is dissolve in the water. Which would not only include carbonate but also minerals that might have came from the water pipe or nitrate or any organic substances that dissolve in the water as well as nutrients for plants. Therefore it is not wise to use TDS when adjusting carbonate. You should use a Kh tester when adjusting carbonate and also GH tester when adjusting GH. TDS give you a general idea of how much stuff is dissolve in water but a tester will still be needed to be accurate. Equilibrium and Replenish provide GH but equilibrium is design for aquascaping therefore unlike Replenish it doesn't contain sodium which is bad for plants and also it provides potassium for plants as well. If you have proper GH and kh but you tds is high, you might dirty water and need water change or filter maintenance or maybe your in coming water is not good. Test your in coming water as well. Also over dosing nutrients will also cause a spike in tds
I am using tap water and My current water in 5 gallon tank is at KH:3dkh PH:7.4 and I want to raise KH to 6dkh and lower PH to 7.0. When doing a 2 gallon water change do I add measurements to raise KH by 2.8dkh in 2 gallons? So the measurements would be 7.5L/80L x 6g = .5625g=alkaline buffer And .5625/2.0=.28125g=acid buffer Do I add this amount every time I do a 2 gallon water change? I am confused about how these measurements Will affect my existing water parameters since I am using Tap water. Or how do I change the measurements?
Hello, you can't permanently raise kh and drop pH at the same time. To reduce pH you must reduce the hardess of water. But naturally in time organic acidic substance will slowly accumulate in the aquarium that will cause the pH to drop even when Kh is unchanged. I suggest focus on reducing the pH first as it is more important for the first.
I think your calculations are wrong if you are using Dkh as a measurement you need to divide by 2.8 example I have 100l aquarium with Dkh of 2. You divide 2 by 2.8 to get meq/l which is 0.714. Then your desired Dkh of 4 also divide by 2.8 which equals 1.42 therefore when using dosage calc you would use 6.5g of Alk buffer to reach desired Dkh of 4. Then you divide 6.5 by the desired PH you want eg Ph of 6.5 is divided by 1.3 therefore you would need 5g of acid buffer. This is my understanding of it if I am wrong please correct me.
The calculation is not exactly correct but good enough. To be exact the dosage should be 16.07g. We can get this dose by dividing the total gram needed by 2.8. This will should how much gram we need to 1dKH. And then simple multiple with the total dKH that is needed to get the correct dose. But a few 0.g wouldn't make much difference and most won't have such an accurate weight scale. Aquarium volume is always an estimation as decoration and filter is not calculated precisely.
@@SeachemMalaysia thank you I must have misunderstood I didn’t do your calculations for your specific tank, I used 100L as an example. Am I correct with the way I am working this out for my circumstances? Btw I didn’t mean to sound so condescending in my initial comment, I did not mean to it was after I read it back I could have worded it better but would have to delete and re type by then my brain was hurting.
For you tank each 2.7g alkaline buffer will raise 1dKH. The total of alkaline buffer use divided by 1.3 will get you the dosage for Acid buffer to get pH of 6.5. But beware that this dosage is accurate only with RO water. For normal with normal water or with items that might alter the pH of water, slight adjustment might be needed. For example CO2 will lower pH while crushed corals will raise pH.
@@SeachemMalaysia Thank you my friend much appreciated, how did you work that out because i will use this as a starting point. I do not use RO water but my water is very soft and not very many minerals? I do use Co2 so in my case i would be better to aim for 7.0 PH or 6.8 to take into account the PH drop.
Normally in Malaysia our water doesn't contain KH or GH. But it's doesn't have some heavy metal. For aquascaping, you'll just need to raise kh for anywhere in between 2.8-4dKH to compensate for pH drop cause by CO2. Start with 2.8 and add some more if needed. Ideally the pH should not drop below 6.5 after co2 have been turn on for a day where it reach maximum saturation.
Hi there I have borewell water kh is 300 mg/l and also ph is high lil bit i want to lower my kh , so should i use only acid buffer ? My tank is 100 liter , please advise
Yes, acid buffer will lower the pH by converting the carbonate into carbon dioxide. Use the recommended dose daily until the desire level is reach. Do not use more then the recommended dose in a single day
Hi there, I’m looking to raise my pH and KH, my tap water has a pH of six and a KH of 2 - 3 would it be okay just to use the alkaline buffer on its own ? I have tried to raise with JBL Aquadur supplement, and only my KH has come up. to me, it seems like I don’t need the acid buffer but I’m not chemistry specialist.
I don't use CO2 injection in the aquarium, even with 3kH, would you recommend just using the acid buffer? Will the pH fluctuate, because when I do a partial water change the pH always rises from 6.8 to 7.0 or 7.2 in the aquarium.
3dkh is enough buffer to maintain a stable pH. You can add acid buffer according to the amount of water that is changed to avoid pH fluctuations. After adding acid buffer you kh might drop slightly but it will still be enough to avoid sudden pH drop.
@@SeachemMalaysia So do you recommend that I only use the acid buffer, in the dosage described on the product label? Thank you very much for your attention, you at Seachem are awesome!!!

Could you clear my doubts? My aquarium is 140l, I would like to leave my kh at 4, and ph at 6.5. What would be the alkaline and acid buffer measurements? My tap water comes out pH6.8 and 3Kh, in the video you did the calculation for RO or DI reverse osmosis water, unfortunately I don't have this type of filter.
Unfortunately you can't raise your existing kh while lowering the pH at once. Acid Buffer works by converting carbonate to carbon dioxide thus lowering the pH and at once. However, if you really need to increase your kh to 4 while in the same time lowering the pH, you could try increasing the carbonate with Alkaline buffer while lowering the pH by reducing the GH with Discus buffer. But we suggest if l possible it would be better to not try to lower pH while in the same time increasing kh. It is very difficult to maintain unless if you are keeping planted aquarium with CO2 injection. The CO2 will lower the pH without affecting kh.
hello, thanks for sharing i wanna ask , my tap water GH6 kh 4 PH8 , if i want to decrease PH to 6.5 for my 40L aquarium, i just need to add 1g of acid buffer ?? cause the direction is 2g for 80L water , once my PH stable at 6.5 , if i want to do 1/3 water change can i direct add tap water in my tank ? after that add back 1g or 1/3 g to my tank ?? is that safe for my fish if i add acid buffer directly in my tank ??
A maximum of 1g can be dose into your aquarium in a day. The dose might not be able to reach the pH of 6.5 therefore daily dose might be needed to slowly drop the pH to avoid pH shock on the fishes. During water change, it is safer to dose on the new water before entering the aquarium. You can use high dosage until the new water pH matches your aquarium.
In that case the second best method is to make a test on a smaller volume of water. For example on 5L of tap water to see how much Acid Buffer it would takes to lower the pH to 6.5 and then just multiple it with 4 if you're changing 20L. This is to prevent sudden pH changes during water change.

Are the calculations the same for tap water? I noticed the chart on Acid Buffer is for RO/DI water. How can I calculate the ratios for my tap water?
Unless the tap water is very acidic or alkaline the calculation is more or less the same as to/di. Minor adjustment to the ratio might be needed.
Does it matter what your current water PH is when doing these measurements?
The alkaline and acid buffer ratio is for reverse osmosis water or somewhat similar water
¿How did you calculate 1.5 to get to 4 dKH?
Because 4dKH is about 1.5 times of 2.8. But to be exact it's 4 divide by 2.8 and result is slightly more then 1.4.
