My thoughts for flow was to rely on the CL for circulation, the flow to the sump really is only to feed the skimmer, heaters and some mechanical filtration.

I second that. Flow through sumps should be kept to a minimum so you don't end up with a micro bubble problems later. That being said you may be able to reduce the size of your overflow pipe. I can't find it now but there was a thread on RC of a similar tank to what your planning.

Are you planning on drilling the bottom of your tank? I've seen at least 1 tank break due to that. Just a heads up.

Thanks for the responses.

My caculations using the RC Head Calculator show 2100 GPH but I see you point. I should look to try and get 1000 GPH from my sump return pump and possibly 3000 GPH through the CL. The question then is how do I determine whether I get 3000 GPH through the CL when the calculator dosn't take into consideration the things you mentioned in your post.

When calculating the head loss on the CL I added 6 ft. as the pump will located just below the main floor to reduce sound. Should I not have done this?

My plans are to order a custom aquarium complete with holes in the rear panel of glass. No holes in the bottom. Thanks for the heads up though.
