Well my 50 gal marine tank has been set up for a bit now. Sump/refugium seems to be running well, I can't really tell if the chaeto is growing well or not, but I know its not dying. Anyway, I recently bought a remora pro skimmer that is hung on my sump as well and that was just added today, we'll see how it does. I have 2 green chromis (had 4, but one jumped in the overflow box and got sucked up through the tube and stuck in the box against the sponge and died, the other has disappeared and I still have yet to find it.) I have some mushrooms (red, blue, hairy) a kenya tree, and some leather that I don't know the exact ID (maybe you can help) . here are the pics
