The sponges fit perfectly in my MC-20 filter. They maintain water flow while filtering effectively. Easy to install and have held up well after two months of use.

Works well with my turtle tank. The mechanical sponge captures debris efficiently, and the biological sponge supports good water quality. A reliable replacement.
