Getting my feet wet

[niteshift]

Hi everyone just a quick intro my name is David and I have decided to take the plunge into the world of saltwater, and would like to start with a FOWLR tank. And i have a few question's, will 55 gallons be large enough for a beginner, will my marine-land 3 stage canister filter be enough. Live rock how much will i need, will i need sand how much and what kind. Do i really need a sump or will constant water changes suffice, what type of protein skimmer is best, and how detailed of test kit will i need. Any and all input will be greatly appreciated. Thank You... ... David
