Where to buy CYA? & acid ?

[aylad]

How many ounces of Muriatic acid to lower your pH will depend a lot on your TA--the higher the TA, the more acid it will take to drop the pH than at a lower TA. It also will depend on how low you want to drop it. With a SWCG, though, dropping your pH is going to be a continual thing, and the acid lasts a long, long time, so I would go ahead and get a gallon of it and you can go from there.

Regarding your CYA, go with what your SWCG manual says. Each model requires a different amount, and it is designed to extend the cell life and let the unit work the most efficiently, so that's what you want to go with--and I believe the SWCG gurus on this forum say that you need to be at the high end of that range.
