Pond items at Wallyworld

FYI, Wal-mart has their pond stuff on clearance. I picked up a bunch of the
sponge filters meant for pond pumps for $1 each. These are the ones that go
over the intake like a sleeve and are made of coarse sponge. I have a bunch
of them standing on end in my newly assembled home made wet/dry. Makes
about a 5 gallon sponge, and the hole down the middle should promote gas
exchange. (I think)

FWIW,
