API Saltwater Calcium Test Kit
Calcium is one of the most important elements in a reef aquarium. Reef invertebrates, such as corals, crustaceans, mollusks, and even some type of encrusting algae, need calcium to grow and remain healthy. Over time, the calcium level drops as it is used by invertebrates, or as it reacts with excess phosphate. The API® Calcium Test Kit measures calcium levels as low as 20 mg/L to help you keep your reef inhabitants healthy. We recommend that you take a few minutes each week to monitor your aquarium conditions and create a better underwater world for your fish. Testing your aquarium water has never been so easy or accurate. Includes 2 test bottles, easy-to-read instructions, and glass test tube.

I’ve used this test kit for three months now and it’s very reliable. The instructions are clear and the results are consistent. I can now easily track calcium levels and adjust my water changes accordingly. It’s a simple tool that makes reef keeping much more manageable.

The test is fast and gives accurate results. I noticed a drop in calcium after a heavy phosphate spike, and I was able to correct it in time. The included test bottles are sturdy and the glass tube is easy to read.

As a new reef keeper, I was worried about water testing. This kit made it simple and stress-free. I now test weekly and my corals are thriving. The only thing I wish was a digital version, but it’s still very effective.
