This is my 75 gallon with what i believe is a 23 gallon long homemade sump. Equipment is a 54x6 t5 light. We have a lot of live rock, not sure of the weight because we bought about 180 pounds. We of course didn't put all the rock in. Running 2 200 watt eheim Jager heaters. 1 in tank and 1 in the sump. Sump now has a super reef octopus xp1000sss skimmer. Middle section is my attempt at a refugium. It consists of live sand, live rock, and chaeto. I have started pods in sump, and the live rock of course had pods somewhat already established. Fish consists of pair of clowns, a yellow tang, and green mandrian. Other live stock includes a sea cucumber, feather duster, and sand sifting star, and a brittle star. As far as coral goes I really have no idea what the actual names are. There is probably 5 different types of coral. We are currently making plans to setup the 150 and then maybe use the 75 as fowlr.
