Bullseye Theo, that is what I did. The water that returns to the tank is regulated by a ball valve.
Bill Cody, I was using pump sizes suggested by aquatececo.com, but used a different pump (same specs). I told them I would have 20 lbs of fish in the system and they suggested 60 gpm. We may have over estimated the head.
M Spinhirne, my dad said the exact same thing. All of a sudden he is involved in the project.
To spread the water evenly over the biofilter I used a bunch of pvc fittings and some pipe and drilled holes in both. I also added an aerator and some bateria.
Thank you guys very much for the help. I have some BG and FH coming in the morning. I will put some pics up tomarrow. Thanks again, you guys have given me some great ideas.
