Hi all, im a little confused by these, are they actually of any real benefit
at all?

Ive seen some on ebay and they claim to remove nitrites and ammonia and can
help with oxygenation etc?

So, are they any good and does anyone know of any in the uk as all the ebay
ones seem to be US ones pretty much.

All I know, dude, is that the tank will cycle a lot faster with a
biowheel. After that, whether the biowheel deal is any good or not, I
do not know.
