I have a question for whoever is looking or following this thread. I am planning to do a sump for this tank I have a spare 20H tank and was going to make it into a sump. Reason I want to do this is so I can put a protein skimmer down there since Innovative Marine 16g is limited on protein skimmers that look nice in the tank and I don't like the HOB skimmers look on the tank as it takes away from the sleekness. I also want a refugium for the added bonus of extra filtration as I am going to be doing bi-weekly water changes and to hide some of the wires.
