Just my .02, but if you ask for help, you ought to listen to it. Seems like you don't like the answers you're getting so you are going to do it your way anyhow. That being said, you might add well take a couple hundred dollars and burn them in the fire place. You would get the same pain in your wallet, but it wouldn't prolong the suffering. From the looks of it you don't want to do the research...so I'll help ya out. With a 10 gallon you are going to need an ATO or automatic top off, unless you plan on topping off with fresh water every day. That's another thing, you shouldn't use tap water. You will need a reverse osmosis De-ionized water filter, or purchase water from a local fish store (lfs). Live rock while not needed, dots make life much easier, it provides biological filtration, biodiversity, and it looks good. Are you planning on corals? If so you will need the proper lighting (coupe hundred bucks if done right) and that lighting may heat your water enough that you need a chiller (another couple hundred). with a smaller tank temp swings can happen fast, and can be deadly. You are going to need a test kit. For fish only, you will need ammonia, nitrate, nitrite, and ph. For corals you need calcium, phosphate, alk. Can you see where I'm going? That's just the tip of the iceberg. Research research research. Then come back and ask questions, research some more, then start putting a list together of things you need. It's a fun hobby, so I don't mean to discourage you, but if you don't start off right, it can be very costly, and failures add up quickly. Good luck
