I have a temporary 29 gallon lightly planted aquarium that is home to 3 juvenile blood parrots and some snails. I'm currently running 2 aqueon quietflow 20s HOB filters. I want to get into canister filters. I plan on upgrading in the future to a 60 gallor so aquarium. What canister filter is the best? I've heard good things about Eheim. What are my options? And what model should I get??
