Crystal clear water w green clumps of algae on bottom….

[tcbdab]

I am not sure how to fix this. My chemistry is all good. The pool is crystal clear but we have chunks of heavy algae on the bottom. We just vacuumed and brushed everything three days ago and there is algae again. I have SLAMmed with high chlorine and used algicide. Anyone have any suggestions??

Hi tcb,

Couple questions:

• When you say "chemistry is all good" what does this mean?
• What do you mean by "SLAMmed with high chlorine and used algicide" what does this mean?
• What kind of algaecide did you use?
• How are you testing?
• What are your test results.

It's hard for me to answer your questions without guessing what you mean. One of the really nice things about TFP methods is there's no guessing. A few reliable test results is all you need to figure out what to do. And it always works!

Looking forward to your reply.

Chris

Have you done a proper SLAM Process and met all three exit criteria?
