Probably made a bad situation worse. Opened pool with tough to sweep gray to black difficult to sweep coating on vinyl liner. Swept it over days. Shocked pool with 6 bags pool shock. May 1-24th weather was cool and rainy. Pool tests perfect. Water looked perfect. May 25th sun came out heater up to 80. Pool looked a little cloudy. Shocked three bags Tues night by Thursday no chlorine. Also noticed white slimy stuff around skimmer inlet and return rings. Cleaned those away, scooped with a net. Now know that was white mold. Read some posts on this forum and shocked pool with 12 bags, removed light from niche to get the white mold out of there. The pool went instantly milky white. Here is where I made bad horrible. We had issues one other year and did a "break point" shock of 19 bags which had been successful one other time, so I did it again. Water really milk white now. Prior to all of this Ph 7.1 Alk 100, CC 0.1 TC 0.1 . CYA 40. After two days we drained 1/2 of the water and refilled. Although not as milky remains white, cannot see bottom. Water is only one year old, liner 1 year old, mesh cover in the winter. One other side note. The other time we had issues we found mallard ducks 2 sitting on our winter plastic cover. We have a mating pair of mallards again. Every morning we find them on the solar cover or in the pool. I am beyond sick as the holiday approaches and weather is 87 and family probably not able to come. Help!
