Need help plumbing sump please

[SandJ]

hi, yup I am female the last time I check hahaha! I am making my cabinet and the tank I will have it done. I just can’t decide about the drain holes if it’s side, peninsula or bottom. One thing is for sure though I want a coast to coast Overflow and I don’t like to see pipes when I walk in my family room.

I have a 120g in my kitchen. It is still freshwater at the moment, but I will be converting it to salt. It has a coast to coast with the overflows coming out the back. The plumbing is exposed, but I plan I’m building a frame to cover the gap between the tank and the wall. It will fill in the gap on each side and across the top. I may mount the top board on the wall, like a shelf, and then mount the side boards on each end so they are removable to gate easy access to the plumbing.
