For a couple of weeks my water was cloudy and started turning green despite shocking with dichlor. I think I may have had mustard algae (there was a greenish-brown powdery substance on the floor--so I started shocking with liquid bleach to get the FC up. I've been scrubbing the walls and floor everyday.)
My CYA is really high 100. (Yes, I've been using pucks and dichlor and now that it's finished I want to get going with the BBB.) And according to the CYA/CL chart I need to keep the FC at 59 with such a high CYA.
Anyway, I've been monitoring the past couple of days and adding bleach as needed.
Friday night
FC=64
CC=0
CYA=100
Sat. morning
FC=59
CC=0
CYA=100
Sat. midday
FC=50.5
CC=0
CYA=100
Sat. night
FC=59
CC=0
CYA=100
Sun. morning
FC=57
CC=0
CYA=100
Question 1--do I need to continue keeping the FC up now? The water cleared up yesterday morning (it isn't green anymore and no more substance on the floor) but it's still cloudy. I have had the pump on 24/7 and had the polaris running about 6hrs per day.
Question 2--if I can let the FC level fall will the CYA start to fall as well (we're not swimming anymore)? Or do I HAVE to drain some of the water to get the CYA levels down. Not having drained the pool before, I'm assuming I'd have to rent a pump to do that and I'd rather not. When I was a kid and we had a sand filter I remember we could backwash and get rid of a lot of water that way but I've got cartridge filters now.
Thanks!
