Had my pool installed last fall and the installer filled the pool with water and did not add any chemicals just sealed the pool. This was in late October and the temperature promptly plummeted into freezing temps. I opened the pool last night and the water was clear but there was a translucent brown slime on the walls and bottom.
8AM Today PH 7.5
I added 6 lbs of granular CYA knowing that it would be a waste to take a reading, then added 3 gallons of 8.25% Bleach. Pump running 24/7
12:00p, FC-8 CC-0 added 1/2 gallon
2:30p FC 8.5 CC-0 added 1/2 gallon Started scrubbing walls and bottom
5:30p FC 9 CC-0.5 added 1/4 gallon Water was cloudier after scrubbing
8:00p FC 9.5 CC-0 added 1/2 gallon
11:59p FC-10.5 cc-0 had a beer
Correct me if I am off in my logic...my plan is to slowly increase the FC level as my CYA dissolves into the water. Not wanting to waste my materials testing CYA levels as this stuff dissolves. I was going to shoot for a FC level of 12 for tomorrow night and then hold it there. Assuming 6lbs of CYA would get me into the 30 neighborhood, and because I have plenty of time this weekend to baby sit the pool without worrying too too much about the sun breaking it down faster then I can add it. That's my plan for now and will adjust depending on what the pool does. After 4 days I plan to test my CYA level and bring it up slowly retesting again after a week. Sound reasonable?
Also after scrubbing i can still feel a little slime on the walls, will the shock help kill that off or do i need to get out there and scrub away until i cant feel it?
Thanks for any input and for the WEALTH of information available on this site. Side note- I am planning on using the TFP method this year with bleach until I get a firm grip on the basics before adding a SWG next year.
