Hi guys I'm new here and am new to Saltwater Aquariums, I have had and successfully kept fresh water aquariums for several years. I always wanted to keep a SW aquarium but just haven't had the space to start. Long story short my wife and I recently bought a new house and she bought me a 70 gallon corner aquarium setup (She wanted the corner aquarium because she wants it in the living room and there is no other spot to put it) Needless to say I'm going to make it SW. Now I have done plenty of research and reading but I am still confused and a lil worried about filtration as FW seems so much more simple. My new aquarium came with an aqua clear fluval power filter good for up to 100 gallon tank. I know it's not the best but I plan on using for now since I have it. Now I assume this will not be sufficient enough and my question is what else should I do? Any suggestion will be appreciated. My plan is to have a fish only aquarium with live rock. I just plan on having a few clown fish, maybe a cardinal, and any other small peaceful fish. I know I'm limited with 70 gallons, but this is my first SW and don't want to go too crazy anyway. I also don't want to go on a spending spree but will not cheap out on products either. Like I said I know what it takes to run and keep an aquarium just not SW yet but I want to learn and get started.
