Why you should be aware of Potassium in your reef tank

Why should anyone care about Potassium? I’ll admit that it is a fringe chemical parameter that most hobbyists do not pay close attention to. I can say that several publications attribute blue coloration in corals to Potassium. If you have been in this hobby a while, you will know that blue is one of the most difficult colors to come across, especially if you are looking for blue coloration that also fluoresces.

Featured Coral – Black Torch Coral

For many, the black torch coral (Euphyllia glabrescensis) is considered to be one of the rarest color variations for torch corals in the aquarium trade.  It’s moniker comes from the coral’s dark, almost black tentacles that wave in the water beneath vivid, contrasting goldish to yellowish tips. The Euphyllia Torch Coral is classified by aquarists as a large polyp stony (LPS) coral.  It has long and flowing polyps with single rounded tips which are visible throughout the day and night, hiding its branching skeletal base most of the time.  Typically, it is sold in shades of brown or green with a contrasting color on the tips on its tentacles. E. glabrescensis is considered to be one of, if not the most desirable Euphyllia species to keep in

Testing for Magnesium in your Reef Tank

This video will focus on magnesium which is an often overlooked ion in our reef tanks. Reef hobbyists interested mainly in stony corals tend to tunnel vision in on calcium and alkalinity. On one hand, that makes sense because coral skeletons are primarily made up of calcium carbonate. On the other hand, it’s an incomplete view of what’s happening in our water and, keeping those levels can be challenging despite our best efforts. Here is where testing for Magnesium can help.
