22,000 gallon plaster pool
FC = 5.5
CC = 0
PH = 7.6
TA = 60
CH = 380
CYA = 35
Water Temp = 80 degrees
I'm using Leslie's (I know that's my first problem) Trichlor 3" pucks in a Rainbow 320 chlorinator and typically shock the pool once a week during the summer with Leslie's Calcium Hypochlorite - 70%. The pool seems to stay pretty well balanced except when the FC occasionally drops from me forgetting to keep chlorine pucks in the chlorinator, and then we will get a some yellow algae. I'll use Yellow Out and shock to get rid of that. Other than the occasional Yellow Out, we don't put any other chemicals in the pool. Anyways, every time I shock the pool, I end up with a really fine white powder in the deep end that we have to vacuum out. I though it was DE getting into the pool until I gave up on trouble shooting and replaced the DE filter with a cartridge filter. Apparently DE was not the culprit since I still have the same white powder problem. I've been researching and think it might be calcium from the shock? But my CH levels are on the low end, so not sure if that's it or not. Any thoughts?
