Calc Test Question

What is the best and most consistent testing kit for Calcium?

I've been very happy with RedSea kits. I use RedSea for Ca, Hana for Phosphates and Alk.

I have been happy with Salifert for at least 15 years. Tried others I just didn't care for.

How do you like the Hana alk test? Is it pretty accurate.

I use the Hanna Alk kit and the Salifert. I get a consistent .02 DKH higher reading with the Hanna. Both are easy to use. Salifert for Calcium.

Red Sea and salifert are both good for calcium. I use Red Sea but both are fine.
