So I opened my pool this year and found it had algae...I went through the ropes of shocking the heck out of my pool and now everything seems to be in range except my cya...no idea why it would be high. Anyway, my pool is holding free chlorine very well, contradicting the high cya readings I'm getting. My question is, I have a cloudy, very faint green tint to my water. I vacuum and change filter daily...so can anyone help to understand why my color is this? I have pics to post if need be, I have a 15000 gallon fiberglass pool, with brand new intelliflo pump. Any suggestions would be greatly appreciated.
