OK, sorry to be so OT here but... what if I bought a filter that could utilize the same bio ball thing's that are in my very established turtle tank? Could I put some of them (not all of them obviously) into the new filter thereby getting some precycling?

Thanks,
Carole

PS could also cut the foam thingy in there and use part of that apparently if I get a fluval in tank filter. The media looks similar enough to put in there even if just in pieces.
