clear out the gravel and add dry sand or buy live sand from someone from here. but some manmade rock from OU812PEZ and then add some live rock from either wolf reef/premium aquarics or that someone is selling on here. change the flouresent bulbs to actinics, add a maxjet1200 powerhead for movement. now sit back for a month or so as the rock and sand become bacteria laden (live) and goes through a cycle. while waiting you can plan what type of lighting to use and what type of filtration (sump,refugium, skimmer).
