I need to bring my calcium level up some and wasn't smart enough to stock up on calcium chloride over the winter.
The best price I can find online is North American Salt 50820 "Extreme 7300" Calcium Chloride Ice Melter 20 Lb at Amazon. With shipping, it will be about $30. The "Technical Details" at Amazon say 100% Calcium Chloride. I found an MSDS here that seems to say it's 60% - 100% calcium chloride, so I'm confused.
Has anyone used this or found a better place to get calcium chloride during the warm months? I can get it from the local pool store, but I'm going to pay about $50 for 25 lbs.
