Pool was left alone for 5 days with filter running. Upon our return, we can't seem to get rid of the algae that seems to appear before my very eyes! Have shocked the last three days, but getting no better. Please help! I know pH is too high--put acid in before shock last night and it was down to 7.8, but up again this morning. Inground vinyl liner pool, 33,000 gallons FC: 11.5 CC: 0.0 pH: 8.0 TA: 140 CYA: 60

The SWG is an Aqua Logic by Goldline Controls. The manual recommends the stabilizer to be 60-80 ppm. Would something in between be best? It also recommends the Calcium to be 200-400 ppm. I really don't want to add any calcium since the water is crystal clear now and I'm afraid it might turn cloudy. I wish I knew more about all this!! Thanks for all the help.

The liner does not have tiling.

We are trying to get water balanced in order to get our SWG going. Pool is inground, vinyl liner, 33,000 gallons. The pool has been open 5 days. Here are results form pool store test: Free chlorine: .5 ppm Total Chlorine: 0.0 ppm Combined chlorine: -0.5 ppm pH: 7.7 Hardness: 80 ppm Alkalinity (w/stabilizer correction): 116 ppm CYA: 15 ppm I put in 4 gallons of 10% pool chlorine last night and it is gone today. I am concerned because pool store wants me to add 10 lbs. of calcium. Is this really necessary? The water looks great as of now. I am afraid calcium will make it cloudy. They also suggested 4 lbs. of CYA, which I know it needs. Can anyone help me with the calcium question? Thanks!
