So the diatoms are practically history (thanks to Lenny the Blenny), but im seeing some new stuff in the tank. On all the white patches where some coraline use to be there is now a pastel green color, darker in some places than in others, it doesnt look like green slime, but it does however look like some of our existing coraline algae... could it be growing back???

any thoughts or comments appreciated :)

There are many shades and species of coralline alga, and as hard as it may be for folks to believe on this board, the purple and pinks we see in out tanks are NOT the predominant spp. in the wild, rather the greens most often make up the reeftop algal ridges on algal reefs. It may be some initial stage of a microalgal growth, (which is what I would tend to believe without seeing it), but there are many spp. of coralline alga that are green, come in different shapes, and different morphologies.

A good thing in your tank!
