This is a coarse pre filter sponge for filter intakes. This bridges the gap between the small and large sponge filters. Working best on most mid sized hang on back filters. Half inch hole for filter intake. Can stretch a bit if needed. Our pre filter sponges are closed on one end to prevent fry from being sucked up.

Intake hole: 1/2 inch

Diameter: 2 1/2 inch

Length: 3 inches

Simple, doesn't clog, safe for my baby cherry shrimp

Title says it all, I tested it for a while, my main concern was that maybe baby cherry shrimp could get trapped in it but they are perfectly fine. I like that it is covered on the bottom part as well.
