    Question about raising my CH

    I ran a full set of numbers today since I haven't done it in awhile. Here they are:
    FC 2
    CC 0
    TC 2
    pH 7.4
    T/A 50
    CH 160
    CYA 70
    Temp43
    Salt 3300
    The CH number troubles me more than anything. I don't want to damage my gelcoat and it's gonna be $250 worth of Calcium Chloride Should I be doing that now, even with winter still hanging around???

    You should be fine where you are now. Raise CH a little when it is convenient, no need to do it right away.

    I don't understand why you are saying that calcium chloride will cost $250. By my calculation you need roughly 20 lbs of calcium to raise CH to around 250, which even at pool store prices will be around $40, or way less if you can find some DowFlake or Tetra. Even raising CH to 350 should cost less than $70 at a pool store (or $15 at a hardware store).

    Duh, I crunched my numbers wrong You're exactly right Jason. Whew, what a relief. I don't know what I'd do without you guys. I'm not sure what Dow Flake or Tetra are. Are the amounts to add the same as Calcium Chloride?
    Thanks a bunch for the quick reply. I'm going to put some chlorine in tonight, once the temps get below freezing and my pump kicks on
    Geeeeez, I'm sooo ready for spring.
