It is not just the holes but the sponge structure that keeps it from clogging. Swiss Tropicals in Ohio sells Poret open cell foam. This is the good stuff. It will last ten times as long as regular sponges, so the guys who pay one time are ending up paying less in the long run.

Here is a really technical sounding article on open cell foams.

Really cool looking test equipment drawings and lots of terminology. but if you keep reading, some of it starts to make sense. :dancing:

Go to walfarts craft section, they have this stuff called Poly Fil Nu Foam in a 22"x22" pad for 5-7$. Stuff is great and can be cut to fit almost any application. I was also pull it apart to make the padding thicker or thinner which makes it catch more or less. Seems to clog quicker then the normal stuff but at the price i don't mind changing the pad every now and then. GL
