white mold

I've tried using the search function, it doesn't seem to work for me. Anyway , it seems that I have white water mold, slimy, tissue paper like. I have a 24 ft round AGP. I have the 6 way HTH chemical checker.

My water is clear, CYA is less than 30. Ph is 7.5, CL is above 5 as that is as high as it goes. I've put in 3 - 1.42 gallons of 8.25% bleach.

I also have put in poly whatever algaecide in to filter. Filter has been running 24 hours, just vacuumed pool, looking good. Planning on leaving off solar cover for a few days, keeping close watch on CL/Ph levels, brushing the pool daily and changing filter sand in a few days. Am I missing anything, any help is appreciated.

Thanks
Jack
