My filter which came with the 55g tank is about to be let go since it's making a lot of noises and the water streams are getting weaker. I have checked most components accesible (which aren't many) but still have no clue why. Anyway, I am now in the process of choosing another filter for my tank. Which brand should I get? I don't need anything too heavy duty since my Oscars will be moved to a 125g in a few months and the current 55g will be turned into a community tank. However I do need something reliable and relatively quiet. You don't need to hear that thing remind you that it's there every time you interact with your fish anyway.
