my powerhead sucks air
i just put my mag 18 in my sump and the intake is about 3 inches under water. some how the intake creates a little vortex or something so small its about the size of a string, that sucks air from 3 inches under the water. i didn't even know this was possible, how do i fix it? puts tons of bubbles into my tank.
Figuring out how to keep my fish healthy is like the pethagorean theorem; there is no solution.
