overflow box
My u-tube in my overflow box that goes from the box inside the tank to the box outside keeps getting air in it. My box is skimming of the top of the water and can't be moved down anymore. Does anyone else have this problem that could help me? Any suggestions would be greatly appreciated.
Also, I have an oily fim that won't go away on the top of my water. Everyone said when I got a sump it would go away but it hasn't. Any thoughts? Thanks Jeff |
