UGF and Wet-Dry Eheim
I just recently made payment on a used 135gal that
will soon be in possession of. It is coming with a
UGF plates. My other two bigger tanks (75gal and
55gal) once employed UGFs before switching over to
canister filters. So the plates just sit on the
bottom. I was wondering if there was anyone on the
list who could think of an advantage to having dead
open space beneath the substrate. Perhaps a downside
is that laterite dust, if employed, would settle on
the bottom.
Ok second question involves Eheim wet-dry filters. It
is possible that I could get one for very cheap. I am
wondering how the Eheim wet-dry would affect co2
levels. Does the Eheim pull in room-air to do it's
thing, or is it sealed completely? (I am wondering
how it would affect co2 levels).
Thanks,
Arthur
