what is the best "calcium chloride" brand?

[fresh]

Hey Chin,

I did try that store "Ideal Pool and Spa" and they don't have neither the dow-flakes, nor the cal-spa!!!

Actually they did have the dow-flakes but in 50lbs bag, and for a 72 gal tank, that will last me somewhere near 100 years so I can't justify buying that.

They had their own brand, which is called Calcium!!!

Can I use that? or is there anywhere else I can go for dow-flakes or spa-cal???

Thanks again.
