For the CRTT Calcium Reactor, we highly recommend Deltec's Calcite Media. It is a premium blend of natural aragonite enriched with essential elements like calcium, carbonate, magnesium, strontium, and potassium, providing optimal nourishment for stony corals, including SPS and LPS types.
The Rowalith Calcite Media ensures vibrant coral growth and stable water quality, making it the best choice for your reactor.
