Do NOT add any more acid!!!!

However if your pH is 7.0 or above, you don't have to try to raise it, either.

There's no need to raise your pH for your SWCG, but you don't have to try to lower it, either, once it begins to go up.

I wasn't clear on what you were saying -- did you lose all your CYA over the winter, or not? Did the brown scale go away?

Notes:
+ Cal hypo does NOT raise CYA. Calcium, yes. But not CYA. You don't want to use a lot of that, on a pool with an SWCG.
+ High CYA is not a necessity, but it lowers chlorine usage and extends your SWCG life.
+ Don't trust that Taylor booklet much -- it's the worst thing about that kit.
