Added Alkalinity up, Pool water turned greenish/yellowish

Postby ragumarc » Wed 06 Aug, 2008 23:06

Pool size = 17,000 gallons. Aboveground - Vinyl lined pool. We opened the pool two weeks ago. Pool was green. Added shock, pool cleared up and was blue. Water sample taken to store. Store advised us to add 30 lbs. of alkalinity up and adjust pH accordingly. We added 20 lbs. of alkalinity and the pool immediately turned greenish/yellowish. Alkalinity level is now at 120 and pH is low. The water looks horrible, it has a yellowish tint. No iron detected during water test. Please help. Will the pool every look blue again?
