Check out this thread to get an idea of what people are using for flow and how much is required.

It seems to be the trend on here to get away from mechanical filtration and just use live rocks and have tons of flow so that there is enough flow through all the cracks and holes of the live rock for good filtration. However, aren't there tons of people that have done it successfully with canister filters? I wish I had the room to put in a sump system so I can pack it with more live rock and sand for filtration but I just don't have the space for that and I was thinking the cannister filter would be my best option.
You mentioned it would be a nitrate factory. Isn't that what you want? You want it to convert ammonia to nitrite and then nitrate right? I apologize for being so new at this and asking some stupid questions. I've only done weeks of reading but no hands on experience so please point out any mistakes in thinking I have. I'm sure I have plenty.

It's not the canister filter thats the problem, it's the foam/sponges. I have run, and know of others who run canisters on a reef tank. Take out the foam, use the canister for carbon, maybe even Phosphate remover, and put some rock rubble in the canister. Works good then. I know others who don't even use a canister. Leah, on here is one example. Just Hang on back skimmer and powerheads. her tanks are gourgous. Nice and clean, and colorful. It's the foam, or BioBalls that do the harm. In freshwater, the surface area is good but not so in a Reef.
The thing about Reefing, is you can make it as simple or as elaborate(and expensive) as you want.

I'll also say Nix the cannister filter idea. I would run a HOB protein skimmer and a HOB filter (like this one but whatever size you need http://www.jlaquatics.com/product/pf...er+Filter.html) full of LR rubble, you could also put carbon and phosphate remover in it as well.
Nitrates are fine in FW but in SW they can negatively affect your corals. FW fish and plants just don't care about nitrates, corals do. As for flow, the best way to get it really does depend on your budget. If price were not an issue I would go with a vortech MP20. If like most of us you're on a budget, a pair of Koralia 4's would be a good place to start. As for the heater, I would personally go with 2 smaller ones. That way if one sticks on, it's not enough to cook the tank by itself. Good luck and don't be afraid to ask questions!
