Carl:

I've seen you mention something similar to the below quote several times-

I generally use a higher qual LC that claims 12.5% but always tests at 14%
I'd like to know how you go about testing the percent value of the chlorine you buy. I could probably figure it out, but I'd end up asking anyway just to confirm. Reason I ask is because I just popped in to a local pool supply discount shop, and he mentioned that he gets Hasa brand LC from the local manufacturer in Eloy, AZ, and it comes in at 17% strength. He sells it for 13.90 for 4 gallons, which seems like a pretty good deal if the strength is legitimate. I haven't seen that high a percentage mentioned here or anywhere else, and I'd like to be able to verify it for myself.

Thanks,
Dan
