Default Aquarium filtering beer?

Is there any reason I cannot use a standard canister filter minus the chemical and biological components to filter beer? I was thinking simply rack the beer to the bottling bucket, setup the sanitized filter, prime and run the filter for like an hour to help remove at least some of the remaining suspended particles. When done the filter could just be tipped upside down and allow the remaining beer to flow back into the bucket.

The inlet is a submersible pump and the outlet would be below the surface of the beer. As long as the filter body was filled with beer before the pump was started only a small amount would be introduced. I plan on naturally carbonating so any small amount introduced should be scavenged by the yeast, hopefully

Updated first post with link to filter in question.

My concern would be with the sanitation of the pump. I personally would not be very comfortable with placing a submersible pump and electrical cord in my beer.
Could you ditch the pump and use this filter with just gravity?

I would run the whole setup using sanitizer for at least 30 minutes beforehand but I suppose one could connect the inlet to an autosiphon and the outlet to a bucket below the fermenter.

How fine of a filter are we talking here? What is available for that device? How expensive is it compared to the regular household canister filters like this one?

I don't think it will work for you. I have set up several aquariums and when you first fill them the fine particles in the gravel (I am salt water and use crushed coral/rock) gets mixed up in the water and all the filtering in the world does little to help clear the water. Time and settling is what clears it up. I think the suspended sediment in my start up aquariums is quite like the suspended sediment in beer. It is so, so fine filtering would take more time and effort than I think it would be worth. I don't think an hour is going to do much to clear your beer if that is what you are going for. If you are talking about what floats on top that filter will do nothing for that either.

That said, you are talking about post fermentation right? Well, by the time you get any results I think you will have exposed the beer to way too much open air exposure for its good. If you do try it I would use the filter medium AND the charcoal too and report back if you are happy with the results.

Funny you should mention this as I just setup a 15 gallon reef yesterday, still a bit cloudy. I was thinking about using filter floss but some activated carbon might be interesting.

That's the issue IMO. Just not able to filter fine enough. That's why the water filter between two kegs came about. A little CO2 and push the beer through the filter. Its about as clean as your gonna get on the other side. Just get the fine mesh filters for the canister.

I also would be worried the carbon would take all the aroma away from the hop additions.
