We just set up a 15'x42: above ground salt water system. When we filled it the water looked ok- a little cloudy but not bad. We have well water. We put in the salt and ran system(cartridge filter) as noted to do. Water still looked ok. then we turned on the ionizer, had green light that system running good and within an hour the water started turning green. I know algae grows quick but not this quick. Tested the water, ph over 8.5 and TA as high as it could read. Could that be why it turned green? Should we add muriatic acid and run pump? Should the ionizer be kept off until run the acid? We have spent a lot of money getting this set up and the kids are anxious to get in it so any help would be greatly appreciated. thanks
