Which thickness of foam do you use, the 2"? I think the Matala stuff is just
floor polisher pad material based on the colours?

I use 1", and in my filter at home it works great, no problems it except
when I draw the water down to pull them out to clean. After I've pulled
about half of them (total 8 in a barrel) the last 4 kind of fold down into
the barrel making it harder to reach them.

The Matala that I've seen is like this plastic weave material I've seen on
cheap flip flops.

Btw, my filter foam is cut a bit bigger then the 22" diameter of the
barrel, so it is kind of curved in the barrel, ~ jan
