[Westley Decastro]

So I'll give you a run down on the tank its a standard 120
It's been running a little over two years now things are growing amazing it a mixed reef with mostly SPS i run radion g4pros
Started a fuge for chaeto skimmers on 24 7
And I've been running rowaphos in a reactor

MY PARAMETERS are
Alk 8.3
Cal 430 to 450ppm
Mag is 1480 ppm
Po4 is at 0.05
Po3 is .2

First off, beautiful corals. Parameters look great (I'm assuming what you have labeled as PO3 is actually NO3?)

How is the flow in those areas of the sandbed that have the algae? Also, when you blow at it with a turkey baster, is it connected like a mat or does it disperse into smaller pieces?

It might be green cyano. Usually it goes away with time and consistent water parameters. You can brush it off of rocks and immediately siphon it out of the tank as well. Don't let it build up on SPS corals because it will choke them out.
