Been reviewing the forum after getting frustrated with the amount of TriChlor powder I was pouring in.
Ordering test kit, but all the cheap test kits indicate the CYA is in the hundreds. Which I believe..
Pool meets all the symptoms, takes lots of chlorine to keep it clear, PH was really low, brought up with Borax. So switched to only liquid chlorine. Two gallons a day seems to be holding off algae.
So knowing only way to reduce CYA is drain/refill and California is still in a drought, what can you do with the water?
I have a hose connection on the pressure side of the pump.
Wash vehicles? Dump it on lawn? (going to remove it anyway). Pressure wash house and deck?
Seems I should block the skimmer intake so it pulls from bottom of pool.
