220 gallon- Filtration help!
Hey, new here. I think I'm in over my head and I'm looking for some guidance. I've had tanks ranging from 10-75gal, but never thought I'd get my hands on a 220 for what I just did. It was definitely an impulsive, couldn't-live-without, buy. Not my first, but my biggest. My worst experience with tanks thus far has been the coffee table aquarium. Anyhow, I want to stock this tank with all new fish, but I need a filtration system. It's a drilled tank, previously used for saltwater so I'm going with a sump. I have absolutely no idea how to buy the right one or even build one. I'm lost and feel like I should have passed this one up. Once I get passed this hurdle I'm sure it'll be my favorite! Any advice would be appreciated! TIA!
