What would happen if one hooked the intake of a penguin 100 biowheel filter to the rise tube of a 10 gallon undergravel filter?. Would this be bad? Good? Just wondering..
It would increase the biological filtration, but might slow your filter to the point where your biowheel stops. Give it a try and let us know!!!
If you do, make sure you keep up on gravel vacs.
Oh yea, I forgot those had square intakes. I wonder if you can heat one of those clear plastic tubes that goes into a sponge filter enough to form it.....
