Does all biofiltration have to be wet/dry as in the bio-wheel?
Would it be feasable for me to get a couple of bio-balls and drop them
into my Aqua-Tech 5-15 filter, would that work or do the bio-balls need
to be wet/dry?

Thanks,
Matt

Most bio-filtration is completely fully aquatic, but the exposed surfaces
of the bio-balls in a wet/dry environment work much better than they
would underwater, so I think the answer is yes, but it will not work
nearly as well.
