Working on a buddies pool Fiberglass, 8500 gallon, Chlorine pool with sand filter, chiller & heater combo. He had it tested because it was a clear & green. his copper read 3.1 so the pool company gave him some liquid and an absorbent pad to put in his skimmer (Don't know what kind of chemical), but the water clear up. He called me again and he started to get algae on the walls. I tested it today with A Color Q x2 tester. Readings are as followed
FC 0.17
TC 0.35
CC .18
PH 6.3
ALK 21
CA 106
CYA 112
I did a 10% water change due to only having skimmer drain and no main drain. Added 6lbs (96 oz) of Baking Soda which calls for 158 oz (figured I would start low), waited an hour then added about 200 oz of 7.55 bleach to bring up FC to close to 15%. On the 15% number I was looking at the CYA/FC chart for slam which calls for FC of 39.
The pool went from clear to cloudy after adding the baking soda to green cloudy after adding the bleach.
Questions are as followed
Will the greeness & cloudiness clear up thru circulation?
Should I try to do more of a water change to lower CYA then start slam process?
I'm trying to make it right for this saturday (6 days away)
