Hello,

Is it advisable to use a large cannister filter over a small tank (10gal)? So it can hold more media.

Thanks

The flow of a 2213 on my 10 gallon is a tad bit high IMO. Others use it like that fine. I feel a HOB is enough on a 10 gallon.

I'm using the smaller ehiem ecco model on a 10gal and it moves the water pretty good. I don't think the amount of media would be as important as how fast the water moves through the media as far as a 10 gallon goes. I had a HOB filter on a previous tank, and I think it kept it cleaner than a canister.

You can slow the current down on the Eccos too. But its overkill for a 10. But then you have a filter ready if you decide you want a 20 or 29.

That may be true for mechanical flitration. For biological filtration, flow can be too high. The bacteria on the media need to be in contact with the water for a period of time, for the bio filter to do its work.

For a large cannister, you can always restrict the flow to slow it down. This, with the large amount of media that they hold, can give excellent bio filtration.
