So i got all the holes figured out and plugged except for the main overflows and the returns. This is where I really need help! I also got the wood to finish the stand however i think I'm going to fill test it first so that if there is a leak its easier to find. Any help you guys can give is much appreciated.
First skin the top of the stand with at least 1/2 ply. Acrylic tanks need a bottom.
The 55 sump is perfect. Your going to need to put some glass pieces in the sump to direct the flow of water efficiently through the sump. Check out 55 gallon sump designs here on MFK.
I like to position my sump right under one of the overflows to save on bends and plumbing. Once I get the sump positioned, for you it would be on the left or right side, Then I like to start plumbing my sumps with the pump.
Pick out a pump you like. Something that pushes 5 to 7X of water through your tank.
You have two overflows, one on each side of your tank, just like mine. I plumbed my pump return right in the middle of the tank to keep the clean water away from the overflows. Put your return there unless you have a hole already drilled that high enough to not flood your sump when you loose power. Once the pump is plumbed then it's time to work on your return drains.
One return should be easy, just drops straight down to your sump. The other return should take an immediate 90 bend towards the other side of the stand then drop down into the same area as the other drain.
The return water should go into some kind of mechanical filter, like a filter sock or something. Then through some bio media then to your pump.
Another tip: I fill my overflows with bio balls and keep them from going into the plumbing by cutting "egg crate" or "light diffusers" to fit in the bottom of the overflow then fill with bio balls. This makes a huge bio tower inside your overflow. It maximizes the bio surface area and really cuts nitrates. It can be noisy so I cover mine with a piece of glass.
Good luck
