Fine Powdery Yellow/Light Brown Substance..Algae Problems

by Dieter

I have trouble keeping my in-ground pool clean. There is a very fine powdery yellow / light brown substance I can't vacuum out. Chlorine / pH levels are normal.

Pool is 5 years old

Any suggestions?

Thanks for your question Dieter

From your description it sounds like you might have a Yellow Algae problem, sometimes called Mustard Algae. This kind of swimming pool algae is normally found in the shady parts of the pool

If these yellow spots can easily be swept away into a powdery form, then re-appear a couple of days later, chances of having Yellow Algae is pretty high.

If you still have the Yellow Algae problem after doing the above, look into a good Yellow or Mustard Algae algaecide.

Hope this helps and have a great Summer
