Testing showed
FC 3
TAC 3
Salt 4700, I have a salt pool and this is high
Cya 125
TA 90
PH 7.4
Copper & iron 0
PHO 200

I poured the whole gallon of algecide in and water turned green the next day. Was clear but had algae before doing so. I don't see any algae on walls, water clear, just green. Cleaned filters 3x, they looked clean after the first cleaning. It's been a month, I need some help! Thanks

Your CYA is to high, check out the correct level for your pool with Pool Levels
You then need to replace some of your water to bring it down to the recommended level
You then need to
Slam with liquid chlorine after checking Chlorine / CYA Chart
