I've been noticing more and more that people put their air pump tubing into their sponge filter instead of putting their filtration tubing around it. I understand that the bubbles exiting the filter allows for water flow through the sponge but wouldn't it be better and more efficient to just use a external filter with tubing to suck water through the sponge?
