It's really a personal preference thing. In a tank that size a couple of powerheads will provide plenty of flow. I prefer to keep things as simple as possible and I'm not one who is traumatized by the sight of a powerhead so I probably wouldn't bother with the CL... :wink:
Louey,
I ordered the weld-on and got that thurs. and some arcylic and it has been in for a while. So mon. and tues. we are closed I will go in and cut a little piece and see how it goes.
Did you install the bulkheads along the bottem side of the sump?
I think they are going to be great all the way at the bottom like that.
And what are the big holes for in those two plates on the out put side?
