Closed loop system

[clowninround]

Can someone explain this to me? I looked it up online and I backed off when I saw 4 holes drilled in the middle of the tank. I remember seeing a pic of spickets shooting out also. I am looking for an effective way to distribute a rather high flow rate evenly across the tank. For plumping I am thinking of using two 1.5" Durso stand pipes and two 1.5" returns with either a 2100 amp master or 3000 amp master. I just really like the comments about this pump, but suggestions are welcome. Thanks for any help, kudos for help : )

You can do a closed loop with the tank drilled or without. This is a site you may know of that explains an over the back closed loop. Look in the lower right hand corner of the page.

I am currently working on one using a Poseidon PS4 going through an Ocean Motions Super Squirt to create random flow in my new 90 gal Megaflow. Heres the link for that
