I was considering adding a powerhead pump to my 125 gallon tank. The filtration is a centered in a sump under the tank, so the water flow is pretty much one-directional (from the output to the input, that is). This generates plenty of water flow, but I wanted a powerhead facing the opposite direction, against the output. Are these pumps safe with octopuses?
