Making it thinner would definitely make it easier to clean. I will have to
try it. I found the foam which I did not know what it was called until
yesterday. Found it in any from 10 PPI to 100 PPI. I figured I would start
with 20 PPI and go down from there until I get the results I want.

Does anyone know a type of sponge that can be bought in 12" wide x 16"
deep
x 12" thick pieces. I am looking for the stuff used in aquariums by
companies like Fluval. I am looking for mechanical filtration to put in
my
stream. I looked at polyfill batting but I don't think you can clean it.

AES or Aquatic Ecosystems www.aquaticeco.com carries reticulated (open
cell) foam PF7, but you don't want 12" thick because it won't come clean
either. What you can get is the 2'X6' 1" thick sheet and trim it to your
desired size and layer and bind it together. That way when it comes time
to
clean you can pull them apart and they clean easily with a spray nozzle on
the hose. It is what I use in my horizontal flow filter
