ok so does anyone know the best way to reduce surface tension in a small betta tank?
apparently the air pump for my undergravel filter is possibly too strong for my tank, I am not sure what the exact problem is. But, if I leave the lid off the bubbles seem to be less of a problem.
I want to make sure my betta can get to the surface and breathe properly, so this bubble problem needs to go away. I dont want to leave the tank uncovered and I want to keep the filter working properly.
