i want alot of stuff. theres no way of me knowing exactly everything that i want to get. its whatever i come across that i like, so i want to build it to handle what ever. i think if i drill enough holes in the spraybar in different directions it will give me a nice current. i really dont have room behind for a vortech. even though if i had to that would be the pump of choice. i can always run a dedicated wire from the breaker box just for the pump if need be. after talkin with jason he seems to think that if i had a double 1 1\4 feed pipe to my sump it would be fine considering it will be less than 2 feet from the sump to the tank. ebay has submersable pumps that run all the way up to 3700 gph and some run as queit as 30 db. im not going to run that much. i think right around 2000 gph would be fine. then its only 2 feet from the top of the pump to the tank and another 2 feet to the top of the spraybar and its straight up so theres not too much head loss factor.
