    Great Website!! I have a fish only 180 gal salt tank. I have two canister filters (Filstar XP-4s) and two #5 Hydro Sponge Filters in the tank itself on power heads with a bunch of dead rock (don’t see any critters on it yet). Currently there are the following fish: Snowflake morray 18″ , Zebra moray 24″, 1 yellow and 1 sailfin tangs, marine betta, 1 damsel. I plan to add a powder blue and 1 hippo surgeons, 1 juv Emperator angel, 1 Biclor angel, 1 Harl Tuskfish and a Tierra batfish. No live corals or invertebrates. The tank currently has been functioning with a bare bottom over the last 5 months. I have been doing a 25% water change every month. QW parametes have been good. I use tap water with Instant Ocean salt. My question should I add crushed coral to add in the buffering with the addition of the following fish? Is there any danger in keeping a bare bottom tank as I have heard stories where toxic build up can occur over time in sand/coral beds? Are there any cleaners that could be added with the morays? I do have a diatom problem I have been battling. Thanks a bunch!
