[My buddy and his wife want a saltwater tank. After explaining mine, i think it might be a little overbaring for him. So i want to start him off with just a 10 gallon, fish only tank with LR and a pair of O clowns. ill probably let him have a few mushrooms too, since they are hardy. im thinking, LS (seeded from my tank), About 10 lbs of LR, clean up crew, and a powerhead. What else would i need. How often would they have to do a WC if it ran skimmerless. How deep should i make the sand bed. Im open to all ideas. Let me know. Thank you.]
