Sufficient flow for nutrient export?

[shullat]

Planning is underway for a new cube tank 36*36*30 roughly 180G. I do not want to go into drilling the tank....for numerous reasons....so I am getting 2 overflows from tunze rated at 1200 l/h each which will feed the sump, return pump will be a pentair quiet one 2400 l/h.

Circulation inside the tank will be provided by 2 tunze streams 6100 with controller rated at 12,000 l/h. Now i know it might sound stupid but will this be enough to get rid of most of the waste material. I am concerned that the overflows might be a bit small for the volume of water.

I wouldnt concern yourself too much with the flow into and out of the sump. You want that to be a minimal amount so your skimmer and work at pulling detritus out. You want to focus on flow in the display to keep as much detritus in suspension as possible.

So far with the Tunzes, you sound like you are on the right track!
