How to Treat Yellow Algae or Mustard Algae in Your Pool

- I describe how to identify and treat yellow or mustard algae. UPDATE NOTE: In the hot summers in Texas, I usually use 1.5 to 2 pounds of shock per cap of Yellow Treat to kill the yellow algae.
Thank you!!!! Finally a solution. The pool shop had me check chemicals, didn't believe the chlorine was ok. Then it was the ph level and then shock after shock. After 2 days it was back. This solved it!! It comes off so easy, just moved your hand in front of it, that I became complacent. Now its solved permanently.
Glad I could help! Good job!
Thank you from Arizona
Welcome!
I'm just amazed how u respond to everyone
For now I can.
@@truelightpoolsllc4441 that's good!! Appreciate it
Praise The Lord❤️🙌 this was helpful!
Glad you liked it!!
Finally someone on the Tube who I can tell understands things like PH and how it can be manipulated to make chlorine more effective. I've left my PH at 7.1 all season after my cya add, which dropped it slightly. After five weeks with no PH recovery, I added borax and increased PH to 7.3. It was at that point when my little mustard problem got bad enough to show up as cc's on my FAS-DPD test even though I've been keeping fc between 5 (min) and target as high as 9 with cya at 60. I think this slight rise in PH let the mustard get a better hold.
You can knock it out with the sodium bromide and shock. Thanks for the message.
Thank you for the video. We have gone through more shock than I want to think about with trying to get rid of this. However, we are on our second bottle of this yellow treat and it keeps coming back. We're following the directions to a T.
I may take several treatments to kill all the algae, it has to be killed chemically. Also can use a Pool RX cartridge.
Hello, thanks for the helpful video. I subscribed to your channel and I also just ordered Yellow Treat. My pool is in Dallas Texas. Can you explain what a water clarifier is? or does? Is a clarifier or some algaecide something I should do weekly as a preventive maintenance measure, and add yellow treat if yellow algae appears ? I guess my question is in addition to shock and chlorine tablets (and Yellow Treat) should I be using a water clarifier chemical or a phosphate remover on a weekly basis to round out my pool maintenance? Thanks in advance.
A clarifier helps clump particles in the water together so a sand filter or cartridge filter can pull them out more easily. A DE filter does not need any help with a clarifier. So if you have cloudy water a clarifier can help with that. I personally don't do anything to phosphates in pools, but according to some pool stores you should. I just think it's an extra expense that is not needed. The water stays fine with proper balance of chlorine and balancing your pH.
Thanks and Gig'em......@@truelightpoolsllc4441
My family pool has had a yellow algae problem for years. As you stated in the video, the local stores have told us to shock and use algaecide but it has always come back. On our end, we failed to do a de-contamination outside of the pool of equipment and pool toys to kill whatever spores are outside of the pool and re-introduced.
This weekend im personally going to sanitize everything that interacts with the pool. Scrub the walls and steps, shock and introduce what you recommend in the video and hopefully see some results.
Do you have any other recommendations for what i should do as well?
In-ground 22k gal plaster with direct sunlight.
No, sounds like you covered it pretty well. Using the sodium bromide along with shock will do the trick to kill the yellow algae.
This is the fist year we've had it.
2 years have passed, is the yellow algae gone?
2 Years and 10 months have passed. The yellow algae became sentient, formed a human-like body and murdered him and his family. All because he asked how to kill yellow algae after just watching a video of the guy explaining in great detail how to kill yellow algae. He may have only shocked the pool even still.
How things went ?
Just got my Yellow Treat I accidentally bought Yellow Out and that one worked a little but you have to use the whole container and at $24 bucks a pop gets expensive-
Oh/chlorine level good brushed pool and backed wash sand filter as well as had it on waste mode as I was useing manually vacuuming pool-do i need to
do anything else before treating pool? Thanks great video PS I live in Kern county California(similar to midland)anyway to parent yellow algae??
Chlorine and Yellow Treat should do it.
Hi, I was having trouble getting rid of yellow algae and that was why I searched online and found your video. Thanks for the help. I purchased the Yellow treat as you suggested and my yellow algae is gone and my water is crystal clear. However, I have another issue it seems, My test strips now show that the pool has no free or residual chlorine, and also show very low bromine. I thought it was maybe the sunlight and water temp of 90 degrees (Live in Dallas). So I shocked the pool and increased my chlorine tab in the pool floaty however my chlorine and bromine still register off the charts low. This started when I used yellow treat. The pool water looks great however the test strips do no reflect that. Also my total hardness and alkalinity now see high also. Before yellow treat they were in normal range....Could yellow treat cause these readings ?
Any ideas?
The yellow treat does help it burn through the chlorine at a faster rate. Make sure your stabilizer (CYA) is in range with minimum being about 30-50 or the sun will be burning off the chlorine also. I wouldn't think the YT would affect other readings, but can always balance them after you get chlorine stabilized.
Great video problem im having is algae would not scrub off .I tried all kind of brushes lots of elbow grease and wont budge .
The chlorine shock used with the algicide will kill it. Sustain chlorine at a 5.
@@truelightpoolsllc4441 THANKS JUST CRUSHED VITAMIN C TABLET SEEMED TO CLEAR IT UP . ANY VIDEOS ON HOW TO CLEAR UP METAL
@@joseconcepcion4677 Cool!
Yellow treat finally arriving tomorrow. Have a 15 foot round above ground pool with spotty yellow algae. After putting shock and yellow treat in do you recommend waiting a certain amount of time before allowing kids in the pool again?
I would probably wait a day and let it circulate well. Then check free chlorine level again to make sure it's around the 5 range and you should be fine.
Gm! My question is should i have my pool pump on once i add the yellow out? If so should it be on recirculate or filter?
If you have a ton of yellow algae in the pool, you can switch to recirculate on a DE filter to circulate the chemicals and kill the algae. Once it's all dead, switch back to filter mode to clean out the dead algae out of the pool. If you have only a little bit you are treating, then you can just leave on filter mode.
Thank you so much for the info. Hoping this works for the algae that just keeps coming back even after shocking and using Algaecide 60.
Yes it will
@@truelightpoolsllc4441 thanks, no algae in sight now after two capfuls of the yellow treat!
@@avenged06x Great, we use it and it works great for us too.
After treating the pool will the dead algae resemble beach sand on the bottom? If so, does it need to be vacuumed out through sand filter or does it need to go through waste. I am struggling to figure all this stuff out! It seems like the whack-a-Mole game...one thing gets fixed and something else pops up! Also....how do I know if the "sand" is dead or alive? Help! LOL
Vacuum out through waste.
I treated my problem with copper sulfate. It killed it and then it looked like sand or D.E. ( I have a D.E. Filter) on the bottom. I vacuumed it a few times and then it finally disappeared. As a maintenance through the season I add some copper sulfate every two weeks.
@@HellOnWheels63 Sounds good. I have used the Pool RX cartridges that are copper algaecide cartridges and they work well for repetitive algae situations.
Inground pool in southern Ohio. Literally impossible to get a pool company that cleans and treats. Husband is disabled and I don’t have the hand strength to scrub the walls. I did the steps and ladder. Our electric cleaner did walls and floor. Getting ready to add yellow out and follow up with shock protocol. Am I able to leave electric cleaner and other skimmers in pool to kill the algae they are infected with during treatment? Thanks for any advice. You are appreciated.
You can leave them in but it is recommended to take electric cleaners out during shock treatments.
Shock and add algae stuff at the exact same time?
Yes
Thank you for the video. I currently have this problem with my pool. 13’x30’ 4’ shallow end and 9’ deep end. I’m assuming around 30000 gallons. I have superchlorinated my pool several times and resorted to adding yellow algaecide. Removed some of the top algae after scrubbing. Have cleaned filter as well. The algae seems to have died off, but I have horrible stains on the plaster itself around the shady areas. Could this be the phosphates still left behind?
Thanks for the question. You say that you removed some of the top algae after scrubbing. If you have to scrub it and it only removed the top layer I would think you still have some green algae on the walls. You want to sustain the free chlorine level at a 5 for about 3-4 days, with the pH balanced to about 7.2. Check and treat in the morning and check and treat again in the evening. The chlorine has to have time to kill stuff that is stuck on the walls and in suspension. I recommend brushing every day during this process and keep the filter running 24/7. This is my best guess of what's going on with the limited information I have and not seeing it myself.
@@truelightpoolsllc4441 Need to also use a phosphate remover
i am at a loss with trying to remove mustard algae. i have about 30,000 gallons. i used 4lbs yellow out with 4 lbs of super powder shock. i vacuumed on waste the following day. 48 hours after treatment, i thought i had gotten rid of it like the store advised me. by the 3rd day, the algae started to appear in the same spots. i used another round of yellow out and shock. by the 3rd day again, it started to show up. this is a saltwater pool with a sand filter. i noticed the flow from the waste on the filter was not a steady flow, water was shooting out in pockets of small blowouts. is that from air getting in the waste line or loose pipe? i decided to change to backwash to see if the flow was any better and it was. i forgot to put in on rinse and when i put it back on filter mode, all this brown/yellow crap entered the pool. probably because it has been 4 weeks since i last backwash/rinse the filter. i have been vacuuming on waste so there was no need to backwash/rinse. seeing all the algae shooting out of the return lines in the pool, do i need to change the sand? it is 4 years old. any suggestions? do i double the amount of yellow out/shock to 8 lbs to super shock the water? Thank you
I recommend using yellow treat product, not yellow out. I usually use a rate of 2 pounds of shock to 1 cap of yellow treat in the summer months. I usually see people not using enough yellow treat and shock. If you have a heavy infestation of yellow algae, you may have to increase the dosage amounts. Also can use a pool RX cartridge to help with algae.
This has been so frustrating for me and I’ve spent so much time and money and it won’t go away. I’m going to try this but I’m confused about vacuuming. Do I need to vacuum before adding the treatment or after or both? Also am I supposed to vacuum to waste? My cartridge filter is covered in this gunk so do I need to clean that first?
Clean your cartridge filter, you don't have the option to vacuum to waste on a cartridge filter. Use yellow treat and shock, in a rate of 2 pounds of shock to 1 cap of yellow treat. For heavy infestations you may need multiple bottles of yellow treat. Can also install a pool RX cartridge to help after cleaning the filter.
@@truelightpoolsllc4441 thank you so much! I will try this today. I enjoy your channel and have subscribed!
@@thatsabundant7678 I appreciate that and glad to help.
Thanks. I was using only chlorine. Its good to shock and use algaecide at start of swim season.
YEP! YEP!!!
Can I treat my pool successfully without a vacuum? Only using chemicals?
Yes.
Thanks for that tip. As a side note, i’ve used a product to reduce phosphates in the water as i was told this takes away the algae food source: seems to have helped. Any thoughts on this?
I know some pool stores say to do this. I personally don't do this in the pools we care for. The main reason is that the phosphates don't turn into algae, they are just food for the algae once you have an outbreak. But the Yellow Treat kills the algae anyway.
Any tips for vacuuming? It is hard to tell if I’m vacuuming the algae or if it is just being dispersed into the water.
Gotta have plenty of suction through vacuum, turn pump on high, turn second skimmer valve off and choke down main drain some if needed to give you maximum suction through one skimmer.
So my mom just got her pool inside fix with new diamond brite. It looks good but now we’re seeing the pool turning yellow. The person that cleans her pool wants to charge her $300 to fix the yellow part of the pool?! That’s prize is ridiculous right?! He stated that the person that cleaned the pool left a residue & that’s why the pool is turning yellow. Is this true? Please advice. But I will definitely try this method to help my mom out financially.
If it's the yellow algae that brushes off, treat with chlorine shock and yellow treat to kill the algae. It doesn't cost $300 to do this.
Is it possible that mustard algae may be harder to remove from vinyl liners than other surfaces? Everything I'm experiencing follows what has been said everywhere I look except that I'm struggling to get it off my liner floor with a standard pool brush. All sources state it comes off easily. I follow the Trouble Free Pool Care system of pool care, which from a chlorine and cya management standpoint, makes much more sense than the "plan to drain" system taught by pool stores, however, the TFP people can sort of get stubborn and not very open to any new chemicals or ideas other than chlorine and SLAM. Mustard outbreak requires a slightly different SLAM procedure. My pool has cya at 60, so TFP says that to shock my pool I need 28 ppm of FC and maintain until three tests pass, but since it's mustard, on the last day, I have to raise my FC to thirty something. I'm worried that, since my algae is not noticeably consuming chlorine, and cc's are only 1 ppm that, I may bleach out my liner using their special SLAM procedures for a mustard outbreak. Anyway, it also worries me putting in this sodium bromine, because I know that chemical companies are notorious for making and marketing products we should never put in pools like copper sulfate, and also, any product with the word bromine in it worries me, as I'd like my chlorine to be effective in the future so I don't know which way to go.
I'm not sure why bromine would worry you and why you would be concerned about putting it into your pool. The Yellow Treat product is the algicide we use on the pools we care for if we have an outbreak of yellow algae. When cleaning residential pools we can't make multiple trips and raise the chlorine up to a 30 for a slam method, the customer wants to keep using their pool. So we shock the pool and use the sodium bromide solution for great results in getting rid of the yellow algae.
thank you! i kept thinking the was dust at the bottom of the pool.
Glad to help!!!
Thank you for this! I was hitting my pool with 15-20ppm chlorine almost weekly to keep the yellow algae away. It was unswimmable as much as it was swimmable, and a severe pain to keep in balance. Once I used the sodium bromide, I was able to keep the yellow algae away for about a month and a half with the first treatment. It just came back this week, so I hit it again, but for the last 5-6 weeks keeping the chemistry in balance has been so much less of a pain. Question: is there a regular schedule for using the sodium bromide I should follow, or should I just use it on an as-needed basis? I have a 25k gallon pool, so I get a little more than 2 treatments out of a bottle. I just want to know if this is something I should plan on keeping in stock on a regular basis. Thanks again!
Glad this was helpful! I would definitely recommend keeping at least 1 bottle on hand at all times so you can treat when needed. We use the Yellow Treat (YT) in the pools we clean professionally on an as-needed basis. We don't treat with it until we see the yellow algae, but as soon as we see it, we shock and use YT. If you want to use a liquid algicide on a weekly basis, that would be fine. A maintenance dose of an liquid algicide that is a Poly- type algicide will work to help inhibit algae growth (look at active ingredient and it starts with Poly). But that's still no guarantee you won't see yellow algae again.
Buy a poolRx and put it in your pump basket. Just replace it once a year. It will cut your sanitizer use in half and rarely need to shock! I put mine in yesterday my pool was green with spots on the wall (gunnite pool) today they are practically gone!
@@andybulldog79 you mean in the skimmer?
@@Anonymouslyme01 no. Directly in the basket connected to your pump. Not the skimmer basket. Idk if every pump has one but mine does
15-20 ppm !!!! And they still survive!! That's a good thing to know so that I don't follow the superchlorination method for mustards
I have the yellow treat ordered. But is there a decent algaecide at home depot or Walmart. That I could try until I get the yellow treat?
Not sure about that.
@@truelightpoolsllc4441 ok, thank you
Hello, when you say to add chlorine shock do you mean the granular or liquid shock or does it even matter?
I was referring to granular chlorine shock but liquid shock will do also. You just have to use a lot more liquid shock than you think to get the same results as granular.
@@truelightpoolsllc4441 Awesome! Thank you so much 😊
@@marcbarrios6441 Sure thing!
Do you know how to clean yellow algae that is embedded in my colored pool?
If it is not killed and removed by yellow treat, shock and even a pool RX cartridge, then the plaster is probably stained and the discoloration will not come out.
Hello i have an insane amount of this stuff, 1 inch layer on bottom but when i turn on pump to vaccum, jests stir it up and i cant vaccum in time. Any suggestions? I let it settle and vaccum once a day been doing for a week+ and nothing. Thanks!
Have someone vacuum out the pool with a cart unit from the pool deck or drain and clean the pool and refill.
So I’m to use the shock and yellow treat together? Do I apply after sunset? How long do I leave filter on afterwards?
Yes use them together, I add shock first then the YT. Doesn't matter when you use them, run the pump all day and night when fighting algae growth.
@@truelightpoolsllc4441 thank you for your response. When should I retreat if I still see it? And how long do I run filter 24/7?
@@Annie-px5ni Re-treat after 2 days if needed, run pump until it's clear.
my pool pump stopped for few days, now I have green algae growing around the pool, I tried brushing it but its hard coming off. Can you tell me what to add to help the green algae. (not yellow)
Balance pH to 7.2 then plenty of chlorine shock will kill the algae.
What brand/type of shock do you recommend to use with the yellow treat?
Doesn't matter if you use calcium hypochlorite or a Di-Chlor shock, but work fine.
When you treat it do you vacuum it out to wast? I have a cartridge filter and it just pushes it back into the pool
On the cartridge filter you don't have an option to vacuum to waste. Wait until it's all dead and on the bottom, then you can vacuum.
Yeah vacuum and make sure you clean your filters aswell
@@slashkokane Agreed.
Hello, do these mustards sit on the walls or only on the bottom of the pool? I need to distinguish between the mustard algae and dust.
Usually walls and steps.
I just found your video, I shocked my pool last night. Of course the algae is still there 🙁 can I add the algae solution today or do I have to shock it again?
Add the shock then add the Yellow Treat, they work together. Chlorine shock alone won't do it.
So, the algaecide that I got says chlorine needs to be between 1-3 ppm when adding it. But when you shock, you shoot your chlorine up through the roof, way above 1-3 ppm. You say to add it right away because the algae will come back within a day or two if you don't. So it's fine to actually add it when your chlorine levels are closer to 10+ ppm still? Thanks!
Yes, I add chorine shock and then immediatly add the Yellow Treat Algicide.
I've been using Clorox algaecide but it doesn't seem to work. I don't think it says sodium bromide.
Probably not.
Hi! I can’t find this product and nothing similar in my country to kill the yellow algae. I found Sodium Bromide . Can I use Sodium Bromide instead of Yellow Treat Algicide? If yes, how much Sodium Bromide I have to use for 100mc of water? Thank you!
Yellow treat is sodium bromide.
What does dead yellow algea look like?
Will it simply disappear?
Usually like some white residue on the bottom of the pool that you can vacuum up.
Thank you for the help.
Sure thing!
I cleaned a filthy cartridge filter and added shock that had yellow algae. 2 days later, the algae came back. Do I have to clean the filter again?
I don't understand the part about added shock that had yellow algae. But anyway, if you have some yellow algae, hit it hard with plenty of shock and yellow treat to knock it out and you should be ok, you shouldn't have to clean the filter again.
@@truelightpoolsllc4441 sorry, I meant I added shock to a pool that had yellow algae
@@alejandrov932 Ok, that makes more sense.
Do I have to brush it get it in suspension and then just throw the algaecide in there and keep the filter running so it goes through and kills all of it or should I only spot treat?
Use chlorine shock and algaecide after brushing.
@@truelightpoolsllc4441 so I have to spot treat or no?
@@macknumber9 No.
@@truelightpoolsllc4441 thank you sir
What is the something we need with the shock?
You need to use the Yellow Treat with the chlorine shock to kill the yellow algae.
Do you add this into the skimmer ala "Perfect Pool", or pour it over the algae areas? I've tried both a regular and steel brush, and the algae will not come off my steps or the corners of the shallow end, where it seems to be the worst.
Throw chlorine shock into the pool and then throw Yellow Treat on top of it. Brush the algae off the plaster as much as you can, but it may take a couple of treatments to chemically kill the algae so you don't see it anymore on the plaster.
@@truelightpoolsllc4441 Thank you! Is Yellow Treat available through Amazon, or can you get in places like Leslie's?
@@sbrave Online mostly. I have seen it in a few pool stores, but make sure it's the Yellow Treat, not the Yellow Out.

Thanks for the comment.
I try to educate a little in my videos.
what about the hard algae that just clings to the walls of a vinyl pool. I need to rub it hard with my fingers to remove it and it feel coarse. its kinda a muddy green color.
That's probably green algae. Use algicide and keep free chlorine level at least a 5 for a few weeks as you brush it occasionally.
Which algae treat ment do you use
Watch the video.
Would Algea all 60 work?
It helps, but I still use Yellow Treat.
Hi I saw dark tan in bottom of my pool .I sweap it it's gone but next day it back.have shock and no phos..help
Do what I say in the video and all will be well. :)
Is Yellow Treat ok for salt pools?
Yes
Is it okay to vacuum the algae up with my robotic Dolphin?
If it has a good filter in it, it may be ok. If not use the pool system to vacuum.
Can it remove the yellow algae that its hard to remove? Even if i brush the yellow stain it wont come off?
Treat the yellow algae and after 1 or 2 treatments it should remove the staining that was caused by the algae.

I have green dust on the floor of my pool should I try to vacuum to waste or to filter. I just don’t think vac head will pick up I have lil wheels and they say not to use brush type with gunite pools so any suggestions greatly appreciated.
The green dust is probably yellow algae. Close off second skimmer and close main drain valve half way. You should have plenty of suction to vacuum to waste. If you want to there is not a problem to use the brush type on a gunite pool, it's just not as easy to vacuum with that one as it is with the wheeled one. The wheeled ones you cannot use on a liner pool.
@@truelightpoolsllc4441 I don’t have liner pool and I have two wheel vac heads and one is low profile for better suction but still not good. I don’t have a valve for main drain it’s old gunite from the 1960s. There’s no second skimmer on one by oool and basket at the filter pump. Pool experts say brush damages the paint do I use gel plastic brush.
@@LubaLuba1 You can use a plastic bristle brush and it will be fine to brush the pool. It's unfortunate you can't vacuum well using your system, that happens on older pools. You may look for someone locally that has a portable vacuum unit to vacuum it to waste. Or kill the algae with chemicals then slowly brush towards main drain repeatedly over multiple days to try to get filter to pull it out.
@@truelightpoolsllc4441how to find which valve is the main drain. We have so many pipes all over 1 area. Thanks
How much yellow treat?
I use 1 cap of YT per about 2 pounds of chlorine shock.
I'm dealing with something I need help with. My water us crystal clear. And it's a fairly small above ground pool 9x15 4ft I have a brown dust at the bottom when touched it disapaits. Once the water settles, it's back. It's impossible to vacuum due to being so fine. Someone help this Mom! 😂
Maybe treat it with yellow treat to see if it kills it, otherwise it may just be fine silt or dirt.
Can I get in the pool to brush this stuff off? Is it safe?
Yes. But usually yellow algae is so light it will brush off easily while you are standing on the side of the pool. If you have a lot and it's been there a while, even when you brush it not all will disappear. It will only get knocked out when you treat with algicide and shock together.
My pool is literally stained ,it doesn't simply wipe off.
What kind of algae that is yellow and will not come off after brushing?
It's probably still yellow algae you just have to kill it with chemicals.

@@jasonday8334 Sure thing.
Thank you , mystery solved.
Sure thing.
So this is partly true however in my experience algaecides are not needed ever! You do have to follow up your powder shock, cal hypo or granular trichlor. You must follow it up with your liquid bleach and you will be good. Haven’t used an algaecide in years. Gimmick I like the yellow treat for clearing up the pool but I’d rather use an oxidizer. I own a pool company so do lots of pools. Consider making your pools an algae-stat pool by using borates in your pool. Try it out, whether you shock with dichlor or trichlor just follow it up with liquid.
Good thoughts, but some pool stores recommend similar to what you said as in just add more chlorine. It doesn't work where I'm at in this extreme environment in Texas. The yellow algae just gets worse and won't knock it out. I will look into borates, have heard of people doing that but haven't done it myself.
BTW., I was at that Alabama game on 2021 at Kyle Field,
Nice!
I heard Disney Parks use Bromination rather than Chlorination for their water features.
Maybe so. I didn't know that.
I thought bromine and chlorine aren't compqtable
You thought wrong. :)
thanks
Welcome
Mine won’t brush off
Treat it.
I got same thing but my ph is good also alkalinity
You can get yellow algae even if the other chemicals are perfect.

The algae are on the walls of the pool. As hard as I brush the algae the algae won’t go away! Would yellow treat do the job getting rid of those stains?
@@walterspencer7524 Yes, some stains remain and are only removed chemically. If they remain after that it’s just stained plaster.
Yellow Out baby!
No, Yellow Treat work better. :)
Man I am struggling with this right now
Yellow Treat and Pool RX cartridge will take care of it.
Our pool is stained
Once you kill the yellow algae in the pool, you will be able to see staining if it's there as you say.
Thanks for tip!!
No problem!
