Increasing Calcium Levels

[Snowshoe]

I was wondering if there is a more cost effective product people use for increasing Calcium other than what the pool stores sell. Under the TFP "ABC's of Pool Chemistry" it was stated:

You increase CH with calcium chloride, sold as a deicer and by pool stores, or calcium chloride dihydrate, sold by pools stores for increasing calcium.

but from what I saw most/all deicer products contain a very high percentage of salt (it seems 75% salt is common).

Deicer can contain lots of different salts, one of them being calcium chloride, but potentially also magnesium chloride or potassium chloride. Or just plain old sodium chloride.

Make sure that you are a) sure that you really need to increase CH and b) the product you are using contains only calcium chloride salt. Whether it's anhydrous or dihydrate doesn't matter much. A little bit of sodium chloride won't hurt, but avoid other salts. If unsure, use a dedicated pool product.

Another option is to use Cal-Hypo for a while instead of liquid chlorine.

What's the CH and TA in your pool and your fill water?

My CH is 60 and TA was 80 prior to starting a SLAM - of which I am just finishing day 2.

I haven't tested my tap water although I just did an approx 25% drain and refill prior to the SLAM and neither CH or TA changed noticeably.

Yeah, a bit of Calcium Chloride is probably not a bad idea then.

Do not add calcium products while you are in a SLAM.

Thanks. I think that's the best price I've seen for 25 lbs.

Thanks. Wasn't planning on it.
