New Salt System and Low CYA

[Phillbo]

I fill an old tube sock full of CYA, tie it off and drop it in the skimmer basket. It dissolved and gets sucked into the filter over night . A sock will hold about 2lbs of crystals .

When adding CYA, slow and patient is the key.

Calcium is pushed by all pool stores (except one salesman in one store I know) for vinyl pools when it is useless. Heaters and SWCGs MAY require a certain level of calcium and it's worth to avoid voiding the warranty. But calcium is a mystery to most pool store guys. The "computer" says add it so they say add it. It's for concrete-type pools, not vinyl ones.

Update-- salt system was installed yesterday afternoon. We added 600lbs of salt last night (recommend 693lbs) but didn't want to add to much. Salt that we used was Mortons granular not pellets and it took a few hours of stirring to desolve 600lbs also added about 4lbs of CYA over an hour period directly into skimmer but my pressure went up about 7 so i backed off and let desolve over night. So far everything is looking good and the transittion was fairly simply DIY.
