Terrible Advice Tuesdays (T.A.Tues): If your saltwater tank doesn’t have coraline algae growing in it, then your tank isn’t healthy.
The rest of the story: The hunt for coraline algae always amuses me as there are hobbyists who hate it and want it out of their tanks at any costs (*cough* Joe). Then there are the countless emails I get asking how to make coraline algae grow in a tank.
The thing to keep in mind is that if coraline algae isn’t growing in your tank, that doesn’t tell you anything about your tank’s health. I’ve seen countless saltwater tanks all with perfect water parameters, thriving corals and there isn’t any coraline algae in the tank. I’ve also seen tanks that look like toxic waste dumps and coraline algae is happily growing on every surface it can attach.
If you don’t have coraline algae in your tank, getting it grow could be as easy as making sure your magnesium (Mg) and calcium (Ca) levels are in check. Or your tank might not be the coraline algae type for some unknown reason.
Whatever you do, don’t freak out because coraline algae isn’t growing in your tank and certainly don’t reach for a bottle that claims to boost coraline algae growth.Browse the Store! Questions?
