Ok well figure ill open up a seperate thread from my 46 thread since I'm gonna have some questions along the way for this setup I already know it lol. For those of you that dont know I just picked up 2- 4'x2'x8" acrylic frag tanks with dual 1' overflows. I'll putting a top on my stand tomorrow so ill have them in place sometime around then. The original idea was just to plumb into my 46 but im starting to like the idea of just doing an entirely New system. What do you guys think?
