I am about to drill my 300G DT for a closed loop and here is my proposed hole layout. The tank is 96"L x 24"D x 30"T.
All of the blue holes are returns and the red is the feed.
It's a 2" feed and the returns are 3/4" fed by a 1.5" manifold behind the tank.
The 2 holes on the bottom will feed the spray bar in the back wil will have nozzles spraying up and towards the back glass. The 4 across the top will flow across and down towards the front glass. These shoud cause a nice rolling motion throughout the tank. The remaining 2 holes on the lower part of the back glass will use diffuser and spray across the sand bed to help keep detrius suspended.
Thought or suggestions?
