Take it out of the tank and scrape the algae off with a blade. Keep a cup of tank water next you you and rinse the blade with the algae in it and then add the water back in the tank. This will help spread coralline around your tank.

Adalius Member. The requirements for growing coralline is pretty straight forward. It's hindered by lack of calcium, presence of phosphates, lack of magnesium, and lack of strontium. It prefers a higher pH, 8. Magnesium should be roughly ppm. Calcium between ppm and ppm. You also should consider not running any sterilization, either ozone or UV, as that can kill some of the algae spores which slows their spread. As little as. Phosphates are a particular stunter because they not only promote other algae growth which then competes for food with the coralline, but there's also been a lot of evidence that suggests that it flat out slows their growth on a metabolic level.

Also, coralline algae is no different than a coral in terms of bleaching. If it goes from a tank with T5s to high up in the tank under metal halides, it is likely going to bleach and die rather than spreading.

It can spread fairly rapidly. Usually in a new tank it takes months to really have noticable growth take hold, but once it starts growing it can be exponential as there's more spore-producing area covered by it, and more spores means more new patches, which means more growth, which means more spores, etc etc.

DaveK Well-Known Member. Once you start getting a lot of coraline algae, you'll find that it's just another problem algae, right up there with cyano, and green hair algae. Coraline is a pain to scrape off equipment, much harder that most other algaes. IMHO, don't do anything to encourage it. You'll get plenty as it is.

It can be a nuisance, in a sense, but I find it more appealing to my eye than most of the other nuisance algaes, and since most of those won't grow over coralline, I settle for getting as much of that as I can.

JandR Member. If you dont already have any growing, Indo-pacific sells little tile squares with it growing on it so u can place it in the back of your tank to help it spread.
