A friend of mine has an A/G 20'x48" which specifies it holds 7900 gal. It has a SWG, [s:2nx5ct9t]probably Intex[/s:2nx5ct9t] Krystal clear. The water recently had an algae bloom and turned green. She took her water to the pool store and her test results were very thorough:
Copper, Iron, Phosphate, Borate, Nitrate, Biguanide, Biguanide shock: ALL = 0
She was told buy the pool store to put a total of 1 gallon of Muriatic Acid to bring down the TA. They instructed her to add 1 pint of MA every half hour until gone. She was slso told to add 2 lbs shock, which I assume was dichlor. Then wait 1 hour and add 2 oz of AlgaeZone Plus.
AlgaeZone Plus is:
Copper triethanolamine complex 82027-59-6 7.1%
Alkyl dimethylbenzylammonium chloride 68424-85-1 2.5%
They've run the filter continuously for 24 hours and the SWG is set to run 4 hours a day. The water is blue, but it's still cloudy. They can see the bottom of the pool if looking straight down.
The pool store told her if she still had green on Monday to shock and AlgaeZone again, but there is no green and the walls are not slippery/slimy.
