Jason Chapman –
I’ve been using FritzPro Calcium Chloride for several months in my 120-gallon reef tank. The calcium levels have stabilized well, and my corals have shown improved color and growth. The powder is easy to measure and mixes smoothly into the water. No ammonia or phosphate detected after use. Highly recommend for experienced reef keepers.

This product works reliably for maintaining calcium levels. I mix it with a separate alkalinity supplement to keep balance. The anhydrous form is convenient and doesn’t clump. No trace elements are a plus for a clean system.
