Canister Filter for Smaller Tanks?
I'm doing a 29 gallon riparium thanks to hydrophyte, probably a South American biotope (not a "strict" biotope but w/e). Most canister filters, including the highly touted Eheim which I wanted to go with, have their smallest model's GPH at a pretty substantial amount for something that has a water volume of only 15 gallons. A bit of an overkill, right? I guess the GPH can be adjusted to be somewhat reasonable (correct me if I'm wrong), but it still seems like overkill. Should I get the smallest model of Eheim or do I have more viable options? I don't want to sacrifice quality and get some crappy no-name brand though. Thanks!
*I wrote this post assuming canister filters are best for ripariums, I'm pretty sure they are but then again, what do I know?
