E.S.V. Calcium Chloride 800 g

Calcium Chloride is Calcium Chloride....this is just a bit cheaper than some of the others. If you can find pure Calcium Chloride driveway ice melter that is even cheaper.

Purchased for wife who is a teacher for a lab, worked great.

if you want to kill aiptasia and mushrooms that have overrun your tank this is better to use than Joe's juice and works like a charm. Just inject unwanted corals with cal/water mix and they die.
