Thanks for your input, folks.
Had an algae farm for a while, as the SWG has failed and the filter broke (pumping DE back into the pool). In preparation for installing the new cartridge filter in a week or so, we've vacuumed to waste a lot, and we're doing the Shock Process. Pool is still a bit cloudy, but is blue.
Haven't gotten a test kit yet, but here are the Pool Store numbers from this morning:
Salt: 2,800 (dead SWG not in use)
After the pool store numbers above, just to continue the Shock, I added 90 oz of 10% chlorine, and 14 oz of Muriatic Acid, to adjust the pH. Brushing the pool now, still a little dark staining in the 'dark areas' of the pool, likely from algae. Still some dust (remaining DE and/or dead algae, we think) rising and re-clouding the pool, but that's inevitable until the filter is replaced.
How do the numbers look to you?
Things I think I know:
We'll have to add Calcium. But when is best?
Don't want to add Stabilizer, at least not yet.
What I know I don't know:
How to protect new filter from complete clogging with residual DE and algae?
How to get rid of staining from algae? (It's a painted pool, and is chalking, too.)
Should we really keep the TA high to help with the chalking, as was suggested by a friend?
Any thoughts and/or suggestions? They'd be appreciated.
