My pool had this green scum on top of pool and when I scrubbed
TF-100
15000 gallon pool fresh water
My cya was 60 so I drained 3200 gallons and refilled then tested
My numbers were
0 fc
.5 cc
.5 Tc
225 calcium
60 ta
40
I shocked it last night
Used the pool calculator
Added 4 gallons of 10 liquid choline
Added 9 lbs of baking soda
Added 9 ounces of Muriwx acid
And today the readings are
17.5
.5
18
200
110
40
It looks better but when I brush I see green stuff like dust
Any suggestions?
