FAQ: I've heard the only way to test for calcium when using Seachem Reef Calcium™ is with Seachem®'s test kit, because Reef Calcium™ has calcium in chelated form. Is this true or will my other calcium test kit work?

A: Reef Calcium™ is no longer chelated, it is a complexed calcium. Also, most tests on the market will work with our Reef Calcium™, with no issues.
