360 gph, thats

ridiculous. I dont know how the guy who had this before me was keeping a decent set up. The only thing i can think of is use both bulkheads in the overflow as drains and have the sump returns come up the back of the tank as with the CLS returns. I was trying to keep as clean of a look as possible but i guess it wil be fuction over neatness. any ideas would be greatly appreciated.
AquaPro, i'd love to hear your ideas on it if you dont mind.
