Terrible Advice Tuesdays: Coraline algae will only grow under metal halide lights.
The rest of the story: Those metal halide manufacturers must really be grasping for straws these days!
Algae needs light and nutrients to grow. Coraline algae also benefits from higher calcium and magnesium levels. And some tanks, despite having light, nutrients, and correct calcium and magnesium levels still don’t grow coraline algae. Is it the lack of metal halide lights? Negative.
I haven’t had a metal halide light over any of my tanks, or any of my dozen of client tanks, in years and I’ve had plenty of coraline algae growth. Heck, in one of my quarantine tanks is lit with a fluorescent shop light and there is coraline algae growing in it!
Forget needing metal halide lights to grow coraline algae. That’s a joke and is truly laughable.Browse the Store! Questions?
