Coast to Coast overflow with 3 drain holes - best way to proceed

[ilikefish69]

I am setting up a 75 gallon with a coast to coast overflow, drilled with three drain lines. I am completely new here and looking for recommendations or better yet examples of how other people have set this up. Pictures are of course worth 1000 words. Thank you for all your help!! I am going to leave the drain pipes pretty much how they were, but what I am most worried about are the three overflow pipes inside the c2c overflow. I am wanting to have the least amount of noise possible and also an emergency drain that would keep from the DT overflowing if two pipes were to get clogged.

It looks nearly all plumbed together. After you fill it and run it, the overflow should tune itself based on the standpipe heights. Looking in from the front, id say the left pipe is the emergency overflow, center is full siphon and right side is your trickle pipe.

Look up bean animal overflow on google for more precise tuning instructions.
