Set it up like joncat shows. I have the same set up, except in the 125 gallon. and set mine up just the way joncat shows.
My tank however has twin overflows. If you have twin overflows, you will find that you may need a higher powered pump to achieve good output to your tank. Once your up and running make sure you have good water movement. These dual nozzles are a good concept but require a higher output pump.
