      Since everyone has had positive attitudes about canisters.
      I will state my opposite opinion.
      I believe they are no better than HOB filters, in fact I think they are worse, because they are "not" user friendly to clean, and fall apart when regular cleaned, so in general will sit and run for long periods of time, becoming nitrate and pathogenic bacteria factories. (bacteria love gunk, and unless rinsed regularly, they fill with smelly gunk, spewing invisible toxic compounds back in the tank, and which is "not" good for beneficial bacteria
      I gave them up years ago for sumps, or back to HOBs because I found there is nothing magic about a pressurized can.

      HOB filter usually provide better water oxygenation than canisters. Wet / dry sumps usually provider MUCH better oxygenation than canisters of HOB's.

      From a purely functional point of view I agree HOB's are generally better than comparably sized canisters... I just have never cared for the look of a HOB on a display tank. I definitely agree sumps rule all when it comes to filtration!

      A sump is good when you have the extra space

      I would like to add that i think canisters work best when packed somewhat sparingly with media. That is to say, don't pack it to the brim with layers of dense fo am but use more ceramic rings, coarse foam, things that aren't gonna stifle your flow as much. Seems like a balancing act between flow and media capacity that gets you optimum efficiency out of em.

      That being said i am a fan and user of the hob, specifically the aquaclears. I find most other brands to be useless in comparison.

      I use a canister as i cannot use a sump due to the configuration of my tank stand and i don't have the room at the back of my tank for big enough hobs to deal with a 6x2x2
      so part of my decision for the FX6 was physical placement of tank and what would work with that
      I have the same situation with my 4x2x2 which has a large canister on it as well
      both are display tanks and i use the output from the canister to agitate the water surface so i have no need to have air stones for oxygen exchange, just for visual purposes

      I am about to switch over all other non-display tanks to sponges only for filtration

      I would state the only downside i have to the FX6 is it has quite a loud hum in comparison to any other canister i have owned

      Im also starting a sponge related project lol but it will be for a display tank. Going to collect river rocks this weekend to build some disguises for them.

      Im also gonna get another length of this stuff as it works great for the lines, if you dont mind fake plants that is.

      The best canister I have owned is the Rena/filstar xp series. Good flow and very dependable. Cleaning is a breeze

      I use to recommend sunsun but a few month ago mine split flooding everything. It would lose siphon a lot to
