Hello all. I am fairly new to reefing but I've read a lot on here. This seems like a great place to get some answers so here it goes. I need to know if what I am running is sufficient or if I need to change something around. I have a 40 gallon drilled tank that I am running a very thin layer of sand in. I have a 25 gallon sump and use a sock filter. It's ran by a 1200 GPH external pump. I use a next reef Bio Reactor and a Phosban 550 for carbon being ran off of a 500 GPH pump. I have a huge protein skimmer that pulls out a tremendous amount of dark thick waste. In the tank I have a 850 GPH, 300 GPH and a 260 GPH power heads plus the 2 returns from down under. The flow in the tank seems pretty good. Any advise as to changing anything or should I leave things the way they are. My only issue right now is the red algae that I can't seem to get rid of. I have a cabbage leather, brown polyps, clove polyps, and a kenya tree that are all doing good and growing. There is a yellow tang (of coarse), clown, chromis, and a fire fish and they are all happy. I use a current Outer Orbit light for a total of 342 watts including the 150 watt metal halide. Any help would be great. The picture of the tank below is before adding the 850 GPH power head.
