i'm in the market for 2 canister filters. price is an issue so it can't be too expensive. the real question is which type should i go for? i need the filters for a 55usg tank and a 60 usg tank. i have cichlids in there now and they are all less than 4 inches but i don't think the penguin 350's will be up to the task once they get a little bigger. eheim, rena and fluval seem to be the most common but i don't know which is better even after the research. any advice will be very welcome
From my personal research, knowledge, experience and what I've been taught, both Eheim and Fluval are the two best brands when it comes to filtration.
From my personal experience, Fluvals are a lot more user friendly, and I mean A LOT. However Eheim do provide a more efficient filtration (they can filter the same tank while using less water per hour, and hence, less electricity). You wouldn't be going wrong with either of those two brands, chances are you could find Fluval's cheaper than Eheim and Fluvals have a 6 year warranty (they do here at least).
You'd want Fluval 405's or Eheim Classic 2217's I would think
