Would adding a sponge filter be in the same category as adding a powerhead when it comes to increasing flow?
Would adding a sponge filter be in the same category as adding a powerhead when it comes to increasing flow? Not saying it will generate as much flow but I just added sponge filters to my tanks on the opposite side of my HOB's and it seems to have obviously increased aeration, but wondering if you would also call that "flow" as well?
