We're getting one thinking no lower then 30 possibly 55 I'm more curious of filtration
I prefer canisters over hang on filters, mainly because I don't want my tanks 4-5" away from the walls, the choice of media options are better, and the available bio-media space is much greater in a canister. For those sized tanks I'd recommend a Fluval 206-406 depending on which one you end up with.
What filter do you recommend for a 180? It's got 3 marineland 400 emp pro-series but that doesn't give me the 10x per hour turnover that I want.
What's the cost of the filter on my community tank I have two aqua clears I like those but I'd listen to you cause I've never had chiclids.
