Mustard algae is usually a sighn of heavy metals like copper in your pool water. You can spend a considerable amount of money trying to resolve the issue, but you may find that simplest solution is to empty the pool and start all over. Stay away from cheap algae removal and copper based coagulants products as they can actually create more problems . Regards Louis
What else can I help you with?
Will SoftSwim by Baquacil harm a plaster pool?
No
Can you swim in a pool with mustard algae?
Test your water for phosphates. Leaves contain it and phosphates are a growth nutrient for algae. Always use a sodium bromide based algaecide when dealing with yellow algae. (Yellow/brown/mustard algae is chlorine resistant.)
Your pool has a stain on thewhole bottom of your pool you tried a chemical called mustard and it did not work any suggestions?
Well if the stain was not algae then why use an algaecide. You have to determine what the stain is or what is causing the stain then treat accordingly. AND PLEASE TRY TO CORRECT YOUR GRAMMAR.
How do you know if mustard algae is in your pool?
You can identify mustard algae in your pool by observing its yellowish-brown color, which often appears as a slimy layer on pool surfaces, particularly in shaded areas. It may also cling to pool walls, ladders, and steps. Additionally, mustard algae tends to resist normal chlorination, so if your pool water remains cloudy or has a persistent yellow tint despite proper chemical balancing, it could indicate an infestation. Regular testing and visual inspection are key to confirming its presence.
Why is there yellow algae forming in the bottom of your cement pool?
Sounds like mustard algae. Usually happens after a lot of rain or warm weather.
What is the pink powder on the pool walls and steps?
It is often called "pink algae", but is actually a bacteria that is hard to get rid of. See your pool supplier. It's appearance often coincides with many overcast or rainy days. It especially loves the white plastic plumbing pools have. I have found the red algae to be pH related. In particular it is encouraged by an acid condition. So, balalnce the pH, then shock the pool.

What is yellow algae and how do you recognize it?
Yellow algae is as the description states yellowish in color. You can determine if you can see a yellow tint on the white or light surface of the plaster or vinyl. You can further determine algae by just brushing the yellow spots -- if it brushes off then it is most likely yellow algae. Mustard algae is similar but will be harder to brush off. The algae usually breeds on the shady side of the pool first then progresses to the rest of the pool depending on how long the pool has been neglected. K
How can you remove an organism growing in the pool that looks like black spots of fine dirt but will vacuum or brush off?
You have mustard algae. Have your local pool store test for phosphates. I can almost guarantee you have them. This makes you a candidate for mustard algae. You should try a product that removes phosphates. LoChlor's Algaecide and Starver Treatment is the best.
What are black stuff growing everywhere in the pool?
It is called black algae. Your pool supply company can provide the proper chemicals to treat it.
Why is your pool getting yellow around it?
Beacause chlorine is not being put in which is making it turn yellow :)
If you change the sand in your pool filter will it help stop the mustard algae?
Unless the sand has been in the sand filter for more then 4 years it's unlikely that you will need to change it.To treat mustard algae. Brush the algae spots with a stiff brush. turn off the pump, use chlorine tablets to treat the algae spots (not recommended for vinyl lined pools). Pour a good concentrated all purpose algaecide on the algae spots. Leave it overnight. then brush dead algae and vacuum to waste. You may have to do it again where the contamination is particularly bad. Check pH, adjust if necessary.Use a good all purpose algaecide. Make sure chlorine level is maintained at proper level to help prevent re occurrence.
When you vacuum the pool the algae returns the next day how come?
Vacuuming just moves the visible algae to the filter. It does not kill it. You need to shock the pool and treat with algaecide. Brush pool thoroughly and vacuum up dead algae. Then clean your filters. It may take more than one treatment to kill all the algae. Also have your pool tested for phosphates. Phosphates are basically food for algae. If algae has a good food source, it can survive in even high amounts of chlorine. Therefore, you may also need to treat for phosphates. It would be best to take a water sample to a retail pool store such as Leslie's. They will give you printout of what your pool needs, amounts or chemicals, and order to apply them.
