A second filter

I have a 46 gallon tank with community fish
All fish are healthy and happy..as far as I can see

I have a Eheim 2213 cannister filter, and I have read that lots of people do not like there that much as the flow is low as well as oxygen

I was thinking of getting another filter...like one with a bio wheel. I heard these types of filters are good as the rotating wheel is always picking up oxygen and adding to the water

Do any of you have more than one filter? And would this be a good idea?

Accepting all advice and suggestions

Seems to me you already have one of the best filters on the market, assuming you have it setup with the correct media such as sponge mechanical, bio-media like ceramic bio-max, and floss for water polishing...
If I was you I sure would trade or opt for a HOB, bio-wheel or not.
Now if all you had a cartridge HOB I'd likely have a different answer

Seeing as most people upgrade to a canister from HOB filters, then I would suggest sticking with the canister and using it properly as AD suggested. If you really feel a burning need to change to an HOB then I would go with aquaclear over the biowheel. I run both on my goldfish tank and wish I had just gone with a canister.

The Eheim 2213 is rated for tanks up to 55g, so it is the correct size for your 46g. And unless you had huge fish, and overstocked, this is all the filtration you should ever need. Eheim has the track record to be the best out there, bar none.

You would do much more benefit adding live plants, if you don't already have them.

Forest fish do not prefer fast water currents, unless they are some of the loach/catfish species that do need this, so your Eheim should be capable of providing all that is required. Just keep it cleaned.

i am no expert, but i do know their are to way to look at filter flow, since you were worried about the flow.. some ppl say alot of flow is best, filter the maximum amount of water per hour as you can get away with, with out blowing your fish around, other say a slower flow is better, gives the water more contact time with the media, so more filtration time.. i am not completley sure which one is best, but both kinda make sence to me...

There are these opposing views, I agree. But what they forget is that water flow in any aquarium should be determined solwly by the needs of the fish. Biological filtration will take care of itself, though it is true that if the water is going through the filter media too fast there is less effective biological filtration. But again, provide what the fish need--this is an important aspect of a community tank, all fish in the tank need similar requirements. And water flow affects them physiologically.
