Unless you have a reason to use chemical filtration... Why are you worried about carbon?
If you have an occasional need, just fill a box filter in with some for a week or two.
If taking media out of a canister and replacing each couple of weeks or a month isn't too much, I would get a canister filter with 1/2 biological media, and then 2 lots of poret foam for the other half.
Then to clean out the filter, replace the foam with the other set, and run the dirty through a cycle on the top shelf of the dishwasher without any detergent. But that is more work than a power filter... But quieter water movement noise.
