Small Aquatop Sponge Filter

These sponges are  a fine sponge. They collect lots of fine particles and can polish water. Great for smaller aquariums from 5 to 20 gallon aquariums depending on load.

Crystal Clear Water!

I am using this as a supplement to my hang on back to help filter and move water on the "dead" side of the tank. After about 2 weeks, my water was crystal clear. While I've never really had water issues, I could never get my tank water crystal clear. Now it is and my fish and I are extremely happy.
