I need to raise my CH in the pool. Do I need to buy this at the pool store or, can I use the ice melt that is 97% Calcium Chloride, If so should I dissolve the pellets first in water before I put it in the pool?
CH - Calcium Hardness
Calcium hardness can be raised with calcium chloride or calcium chloride dihydrate. They are available in some areas as Peladow, Dowflake, Tetra Flake, or Tetra 94, often sold as a deicer by hardware stores, and some big box stores, in colder climates. Pool stores will carry either calcium chloride or calcium chloride dihydrate under a variety of names, including Hardness Plus, Balance Pak 300, Calcium Hardness Increaser, etc. Calcium products should be spread across the surface of the deep end of the pool.

It helps prevent cobalt spotting and helps protect fiberglass from staining. Could be more reasons....?TripleB4me said:JasonLion said:Keep in mind that when you dissolve calcium chloride in water it gets rather hot. This isn't usually a problem as long as you are aware of it.

Why does one need calcium chloride in a fiberglass pool? Is it for equipment reasons?
No, those are the two significant issues.Butterfly said:Could be more reasons....?
Yep, the Recommended Level is 220-320 for fiberglass.brettman40 said:MY CH is reading at 210 I would like be a little higher.

Also, use a non-reactive stirrer, like wood or plastic.mynewpool said:JasonLion said:Keep in mind that when you dissolve calcium chloride in water it gets rather hot.

I know how that is. I was told the same thing and felt the bucket and it was hot. I also touched the end of the pole I was using and it was hot. Had to be careful when I was pouring it in.
The recommendation I've seen is no more than 2lb calcium chloride per gallon in the bucket, to avoid excessive heat.mynewpool said:JasonLion said:Keep in mind that when you dissolve calcium chloride in water it gets rather hot.
