Hanna Instruments Checker HC Calcium Reagent

Q: I'm confused...my calcium reagent came with powder. So this is for hanna checker and doesn't require the reagent B?

First of all, make sure that you ordered the correct refill for the type of checker that you have. The refill for Checker # HI 758 uses a clear reagent which is combined with purified water. After C2 come up on the checker, add the purple powder and 0.1 mL tank water. Always follow directions. The checker will calibrate the number of ppm that is in your tank water. This is a marine checker, not a fresh water checker which is quite different.

Q: Why so expensive? It's $23 at the Hanna website.

Well, check other websites like amazon or one of the fish stores on line.

Q: Does this contain packets with purple reagent?

Yes, it contains both reagent A and B.
