A friend of mine has some breeding bettas. In their tank, he has a small sponge filter where the sponge is on the bottom and the tube comes up from it.
He has the filter installed so that the majority of the tube is out of the water. As the filter sucks up the water, it creates bubbles in the tube, and only 1 or 2 bubbles actually overflow into the tank, drip down the outside of the tube causing a very very small ripple when the bubble hits the water.
Is this actually going to work as filtration? I thought the tube would have to be submerged and allow the bubbles to come out of it. He indicates that it actually filters the water through the sponge, and you don't have to have the entire filter in the water. He said when the baby bettas come, they will have filtration without a lot of current to knock them around.
