I can't find any online resources for how to make a sponge baffle. Can anyone help me out here, and tell me how?
I have an external filter.
Use an aquarium sponge/foam - AquaClear and Imagine are two brand names. Rubber band it to the filter where the water comes back into the tank.
Adjustable - pull the sponge/foam up for more flow or down for less flow - no sharp edges and another place for the good bacteria to grow.
I am attaching a picture of one of my betta tanks to show you what I mean. When the hood is closed, you don't really see the sponge.
