Whats goin on, hope everyone had a good holiday. My name is rich, I am a college student and i am looking into getting a saltwater setup, I have never done this befor so i have many questions befor i start investing more money than i already have. To start I am looking at buyin an tank about 30 gallons in size, and because of this i have already bought a Marineland H.O.T. Magnum Hang On Filter. The spec sheet says it can handle up to 50 gallons so i thought it would be fine for my application.... if you can help me find produst that i need, or will want to use for cheap(remember i am a college student $ is tight) it would be greatly appreciated thanks
