Ive always used HOT filters and had decent success with them, but everyone seems to always be recommending a canister style...my question is this. Im looking for a decent, cost effective canister filter for my 55 planted mbuna tank(something with excellent mechanical filtering capabilities). I would like to keep it around 100 bucks if possible...can anyone reccomend a good setup for me?? Im not looking for suggestions to keep my HOT filter(it does serve its purpose), i just want to explore some other options.
