I have a 75 gal. ciclid tank. It has a corner overflow going to a wet/dry. I have a 1400 gph pump on it. I just put a drip set-up that drips 1gal p/hr. Im trying to cut down on the amount of time I have to spend on keeping the tank up. I was thinking of putting a undergravel filter and running it it reverse to push all the crap up so it will go through the filtration set/up. I was looking to see if there was a power head with alot of power in reverse. The most I found was 175gph. I dont think this would be enough. Has anyone done this with an undergravel filter? Should I put it on a timer or have it run all the time? Can anyone reccomend a power head to use, or would I be better off using another small pump from the wet/dry and plum it up to the undergravel filter? I know Im still going to have to clean the tank, but I want to do whatever I can to keep the tank as clean as possible. Any suggestions???
