How to Modify Your Sponge Filter to Create Smaller Bubbles

TL;DR: This is a guide on how to modify an Aquatop Sponge Filter to create smaller bubbles.

I made this video as away to give back to the community.

The Sponge Filters work great when you have multiple aquariums and need a way to create circulation and filter the water without have multiple Power Filters.

However, they do make a lot of noise due to the huge bubbles they create. The massive bubbles are also ugly, IMHO.
