Hi All,
I got off to what I thought was a great start opening my pool, crystal clear within a day and all seemed well. Water temp was about 60 degree's when opening, and SLAM was quick and easy. My CYA level was low however when opening, approx. 15-20. I added stabilizer to bring it up to what I thought I figured would be about 35-40, however I ended up at about 75. After raising the CYA too much I decided to just leave it and let it lower itself through backwashing throughout the summer, and adjust the FC levels accordingly.
Fast forward to about 2 weeks ago, we had a big spike in outdoor temps, the pool water turned to a very slight green/bluish color rather than clear. My FC levels began to drop quickly, leading me to another SLAM which has now lasted for about a week. I am not sure if I have an algae problem or if possibly this is white water mold? Any help would be appreciated as this has taken longer than expected to clear out and hoping I am not missing something.
I have been doing my best to keep the FC between 28-30 however it seems to be dropping a few PPM every few hours, so it has been tough to keep it exactly there. Before shocking I had the PH to about 7.3. As seen in the pictures, I just discovered this stuff in one of the skimmers, as well as along the tile and corners of both skimmer "mouths" and I believe there is some also growing on the return piping near the eyeballs. I have begun scrubbing them like crazy since discovering the growth and am hoping that scrubbing will loosen everything up to die. Thank you all for your help in advance and let me know what other info you may need!
