I have a friend who needs some help. He is setting up a tank that has the return and drain drilled just a few inches from the bottom of the aquarium. If he did a wet/dry (fish only tank) or some kind of sump he would put a check valve on to take care of back syphon from the return. However, if the power went out it would continue to drain down until the tank was almost empty. Is there any other option for filtration? He doesn't want to put a pipe up the tank from the drain because of asthetics.
Any help would be appreciated.
Thanks!
