I drained 75% of the pool water to lower CYA and CH.
Before:
FC: 0
CC: 0
TC: 0
pH: 7.4
TA: 130
CH: 600
CYA: 130
Water is clear. Scaling with yellow algae imbedded.
Tap water:
pH: 7.5
TA: 200
CH: 200
After replacing 75% water:
FC: 3
CC: 0.2
pH: 7.7
TA: 170
CH: 290
CYA:40
Water is clear. Yellow algae still present, but seems reduced much.
Actions:
added dry acid to reduce the pH. (target 7.4)
added chlorine to shock level. (target 15)
Leave the fountain on to aerate.
Leave the pump on.
Will brush once a day.
Am I on the right track? Thanks everyone for your inputs.
