So after a week at shock level, I have finished the SLAM. OCLT is less than one, CC is 0.5 and water is clear. Thanks to all of you who helped me get started and work through my first SLAM. It is great to see the main drain covers nice and clear again!
Latest testing (TF100 test kit)
pH 7.5
FC 19
CC 0.5
CH 250
TA 210
CYA 40
I am not sure about the accuracy of the pH given the FC level.
I understand the FC is high, and I assume I will just let it come down to a target of 5 on its own over time.
I will use PoolMath to figure out how much MA to add to bring the pH down to 7.0 to 7.2 then aerate to raise pH.
My question is that the water, although really clear again, has a green tint to it. Any ideas on causes and resolution?
Before the SLAM, the pool store said phosphates were very high at 1500, but I have not messed with that. I am thinking maybe I can now, but am not too concerned right now, although I wonder if that would cause green. Could it be metal like copper? Could the vinyl liner be discolored from the severe algae bloom? Or from the super high FC levels (35 to 40) I hit when I thought my CYA was 65 or 70 early in the SLAM?
Any thoughts would be appreciated.
Thanks
