Update: Black algae is under control, pool looks great. Thank you forum.

Thank you. OK, I will try to sample the micro spots. The pool looks much better - it used to look like a Dalmation a week ago. Still failing overnight FC test -third time. Dropped 5 ppm in 7 hours at night. Keep brushing, vacuuming, cleaning filter, SLAMing, etc. Have been aiming for 20 on the...

Thank you. Yes, I am having trouble with a big body of water that I only enjoy the 3 most miserable hot months out of the year. But I am committed to keeping the pool balanced and sanitary until or if I do something different. Here are some pictures: Overall pool: Main drain and light...

Continued. I filled the pool and I've brushed the pool by hand with the stainless steel brushes using scuba equipment. One can see plaster, dirt and algae much better up close. Plaster looks white from above. I've been SLAMing and running filter 24/7. After hosing down the cart filter a couple...

OK. I cleaned the filter but when is it a good idea to do the dishwasher cleaning? I will SLAM and do Overnight tests.

I'm in the process of treating a black algae infestation. I've been lax and lucky for the previous 6 summers but lost this year to black algae and am now a convert to TFP methods and test kits. Thank you for being here. I've read everything I can on this site about black algae and think I...
