pH above 8 15ft X 48in Intex

[Pappy]

I can get Kem-Tek CYA and Clorox Polyquat 60 at the local Lowes. We already have several jugs of 8.25% bleach. I was thinking I'd get pool clean with bleach, then bring the cya up to 40 or 50, after that see what I need to do with the pH. Will it be a big problem if the pH is too high for another week or 2? How much CYA should I add to 4500 gallons at a time. I think I read wait a week between doses.

I have read the "Best Guess", and LOTS of other great stuff here and at PoolSolutions.com.

I intend to have a SPARKLING, SWEET, SAFE pool before the first scheduled outing.

We won't be gone more than a couple of days until some time late June, after that, probably 7 or 8 days at most.

Thanks
