Let me extend the formal welcome as you are a new member: Welcome to FishTankForums!
Absolutely. A skimmer will help out, but as I have said before it is not necessary. You can easily get through the cycle and even the first few fish without one. Go ahead and take your time to save up. This is better because while you are waiting you can research into which skimmers you would like. Getting a quality skimmer is tougher than you might think, not all of them are made equal.
I have heard rave reviews about Red Sea Berlin skimmers, Ramora Backpack skimmers, and the Coralife Super Skimmer. I have not had any direct experience with these but I have had my eye on the Berlin and Coralife skimmers for a while now and am trying to decide which of the two to go with for myself.
