Stylophora are branching small-polyp stony corals from the Family Pocilloporidae. Stylophora shares that family with Pocillopora and Seriatopora, and the three together are the only genera in the family. As a result of their close relationship to one another, all…
Salty Q&A: Calcium and Alkalinity Out of Whack
Question I’m having an issue with the calcium and alkalinity levels in my reef tank. Right now, the calcium is at 380ppm, which is at the low end of the acceptable range, and the alkalinity is at 10dKH, closer to…
Reefing from Afar, Part 3: The Bare-Bones Basics of Automation
In Part 2 of this series, I discussed some of the possibilities for automating your reef system based on your needs. Now that you have a few ideas of what you can automate, I’d like to offer a simple recipe…
Techniques for Maintaining Calcium and Alkalinity in Reef Tanks
Calcium and alkalinity are vitally important chemical parameters in reef aquariums. They are used by stony corals to build their calcium carbonate skeletons. A lack of calcium and alkalinity in the water will inhibit the growth of reef-building corals and…
Marine Aquarium Antacid: Understanding Alkalinity
When I first made the switch from freshwater to marine fishkeeping, I was somewhat befuddled by the term “alkalinity” as it’s typically used on the saltwater side of the hobby. During all my years of keeping freshwater systems, I had…
