I keep pool at 8 ppm and it drops to 5 each day. No OCL. Something in pool gathers at seams and wrinkles and when I sweep I discover Iíve got a dull covering of something that sweeps into a greenish cloud. Slammed at 16 for several days brushing 2 times a day. 1.5 chlorine loss first night and no chlorine loss at all second night. Water is crystal clear except when I brush it has the green cloud still. In several hours I see the stuff gathering in seams again -- although I havenít turned off the pump in 4 days. Behaves nothing like mustard algae (climbing walls or primarily in the shade).
FC -- 16
When not slamming: FC Ė ranges from 8-5ppm
CC -- .5 (clears with one drop)
Using k-2006 test kit
First time this happened I decided it must be pollen and let it go after I passed all 3 tests and then I got a RAGING algae bloom. Slammed again at mustard algae levels and took about a week to get it back to passing all 3 tests again. Took all necessary precautions to prevent its return but now it is two weeks later and Iíve got stuff gathering on the bottom again.
This is the third time this summer Iíve been through this cycle and it has just started again. I know I can slam at mustard algae levels and get rid of whatever this is BUT I need to figure out how to keep it gone. Three kids (one of them special needs) donít get why they canít swim and neither does mommy.
Anybody got any ideas?
