[Subsea]

In the past, I have used GAC in a tank to remove a by product of macro: DOC. Ken Felderman has written peer reviewed articles on methods to remove DOC. His research shows that protein skimming removes 30% of DOC, GAC removes 60% and the inhabitants of a mature reef tank remove 75% of DOC.

I am not interested in nutrient export. For me, it is all about nutrient recycling. I want my nutrient sink to be corals, sponges, and micro inverts including the pod brothers (amphipods and copepods).

On my 75G Jaubert Plenumn DT and my 30G mud macro refugium, I have decided to remove macro and lights. I will place eggcrtate on top of mud and stack some dead porus rock on top of eggcrate. I have ordered a cryptic sponge starter culture and will seed this tank with it. I already have large populations of pods and worms.
