What is this algae?

[Caleb423]

I am just curious as to what this algae is and what is the best way to control it? I am assuming it is due to low flow since it is only occurring directly above the sand bed and behind the rocks. It is pretty soft and easily removed with my mag-float, and is only growing on the glass.

Water parameters:

Salinity: 1.025sg
Ph-8.2
Phosphate- 0.25ppm
Nitrate- 5ppm

idk...but you got some seriously cool coralline algae going there...

Thanks! Coralline grows like crazy in this tank for some reason

Looks like green coralline algae. Coralline comes in different colors and green is one of them.

Would coralline scrub off easily with just a mag-float scrubber? I know that the pink is impossible to remove without a razor blade

Yes sometimes. I have the same stuff in my tank. Sometimes it comes right off with the mag scubber and other times its a pain.
