The equipment I have for my 75 gallon aquarium is a cone protein skimmer some t5 lights and a small sump that has a bio ball trickling filter (I am going to be upgrading it soon). My t5 lights are set on a timer that goes from 8:00 to 8:00. The livestock I am housing is, a mated pair of black ocellaris' clownfish, a coral beauty, a blue devil damsel, a goby I can't find an ID for, and today I just got a leather jacket file fish. I also I have a skunk cleaner shrimp a peppermint shrimp and a CUC.
