Hi all. I'm looking for advise on canister filters. I have a 70 gallon tank, no plants, currently housing a Clown Knife fish @ 20 inches long and 2 plecos. I will be adding 3-6 Tinfoil Barbs in the near future. (as soon as they're large enough and I'm sure that they're healthy) My Millennium filter just kicked the bucket recently, and we're looking to get a canister filter. I would like to keep it as chap as possible for now, as we also have to look into getting a new hood soon. I'm wondering what the advise is. We've looked at Fluval 303 vs 304 vs 304 vs 404, and I don't really know the difference. Also been looking at Eheim. I would appreciate any advise y'all can give. Thank you!
