Something similar came up a few weeks ago, sorry to start a new thread. I am growing weary of the HOB filters and am looking for options. I am looking for something I can stick in the cabinet, will be quiet, and would be good for my planted community tank.

I do not know much about them, but it appears they are powered by a powerhead in the tank. Is that correct? I have several laying around, but was not sure if the guppies/tetras/inverts in freshwater appreciated that much water movement. Any thoughts?

I have never had a canister or a fluidized before. What is the scoop on these filters? Opinions?

Oh yeah, running a 46 bow front now, but may still switch everything back to the 75 if I can find a good spot to put it. So if possible any model suggestions might take that into consideration.

I don't use mechanical filters on my planted (dutch) style aquariums.

is there a pump in the canister filter then? Having never used one I am not sure how they work. I am looking for something a little less visually intrusive then the HOB filters.

Years ago I had a magnum 350 canister filter. The pump and everything is enclosed in the canister. I had one hose that pulled the water in and then I put a "t" in the outlet hose and it returned the water out towards both sides of the tank. You still are going to see at least two parts in the tank so I don't know if I would switch if the only reason is visual. I felt the canister did a great job but it came with the tank I had at the time, that is the only reason I had it. It was on a75 g with an arrowana, 2 oscars, and 2 pacu.

The typical canister filter uses a simple siphon effect to move water from the tank to the bottom of the filter. The water flows up through various baskets of filter media to the top of the filter canister. An impeller located in the top part of the canister filter pumps the clean water back into the tank. The specific details vary a bit from brand to brand and model to model but they all work about the same. Some of the older Eheim filters don't have any baskets and just build their filter media layers by having you, the owner, manually layer the media in your filter as you build from bottom to top. The principle is much the same but the baskets most of take for granted are missing from the canister.

interesting, just an impeller driven pump that can be hidden in the cabinet. Thanks for the information, I will spend some time researching Canister models.

I have a Fluvall 205 and it just sits on the floor next next to my aquarium stand and It is pretty quiet, I would think that you would barely be able to hear it all if it were in a cabinet and theyn are very easy to maintain. It has what they call an aqua stop which is basically on valve that lifts on the hose to stop the water flow and anohter to disconect the hoses,.Simply change your nedia and I uses go ahead and fill the canister back up b4 attaching the hoses back. This just helps to keep from priming the canister back up, but you may need to prime it anyway but it has a really convient primer button just in case. In fact my airwall pump makes more noise thean the filter. Hope that helps. Sincerely Badfish
