Using Pool Math, it looks like about 50 lbs of calcium chloride would raise CH to about 320 and reduce CSI to about -.3. which gets me to a good place on CSI. Think that's my next step. I'll keep you posted. Thanks.
How about Safe Step 7300? Also sold by Ace. Product Data Sheet says it's 100% Calcium Chloride. Back of bag says "High purity 100% calcium chloride."
Sds: Sds SS7300. == 94%. @mknauss?How about Safe Step 7300? Also sold by Ace. Product Data Sheet says it's 100% Calcium Chloride. Back of bag says "High purity 100% calcium chloride."
Sounds good on the CaCl. I will likely go with the SS7300 since the SDS says it's 94%. Also cheap and easy to pick up at Ace nearby.After a review of a 1/2 dozen threads, if you get an SDS of 90% + CaCl you should be good.
Can't help you on the Bromine. I would suggest a new thread for your Bromine question.
7 pages worthCan anyone give me the "skinny" on maintaining proper water chemistry with bromine?
I see a gallon of this stuff (see pic) along with about 3 gallons of liquid chlorine (12.5%) in the storage room to be used for closing the Association's outdoor pool tomorrow. Can anyone comment on this Winterizer that the pool comapny is putting in the pool. Is this good stuff or unnecessary?

Thanks. Makes me feel better that they are using the right stuff. Looks like their process is to add about 3 gals of Cl, the Polyquat, then drain below return lines and cover. Haven't seen it yet, but they tell me it's a mesh cover.It is Polyquat 60 and often used for closing. It is a good insurance policy over chlorine.
