I helped an acquaintance of mine last year with his pool. He called this week saying he needed a hand again... boy did he ever. Green mess and lots of plastic circles from his disintegrated solar cover, since removed after opening. The pool had been opened "professionally" for weeks so how could they be there? Even if the pool was green, it should still be skimming surface debris. I guess I assumed too much. The plumbing lines on his AG pool had been hooked up backwards! Water coming up out of the skimmer, being sucked in the return...
With that fixed I went to testing the water. Full on CYA to ammonia conversion. pH >8.2. 0 CYA. 0.5 FC and 1.5 CC after adding a gallon of bleach. Not too terrible though. Only took 2.5 gallons of 12.5% bleach (~9000 gallon pool) and we were holding chlorine again. Patented pink soccer sock in the water with some CYA and we're on our way! We'll see if we can work on keeping a better pool with actual circulation. And this was the pool service that's more recommended than the other in our area...
