(would like inverts) (first time marine, about 2 years FW experience, current 20gal FW, 55 gal empty). I realize that I will need a sump, a protein skimmer, LR in the tank and some in the sump, LS in the tank, powerful fluorescent lights between about 6500 and 10000K, at least two heaters, and some sort of in tank water circulation. I have also determined from what I have read that I will need to cycle this with just light and LR for upwards of 3+ months. I will also need to make at least weekly 20% water changes <20% is a serious water change on a weekly basis!
