So I think I have mustard algae. I've been following the TFP method and my water is gorgeous and crystal clear. Every time after I SLAM the pool or brush the sides, I still keep getting some yellowish algae growing just in certain spots. I never let my chlorine drop under the minimum (in fact, I tend to keep it a little high thinking it would kick this algae). Today I found the instructions for treating mustard algae but I am wondering... is it still worth treating this late in the year?
Thank you for your input!
