Building a wider stand than aquarium width question

[cvrle1]

Hello everyone, I decided that I will use ever popular REs stand template for my stand. I do have a question in regards to width of stand vs tank width. My tank is 18" wide, however sump that I am looking into is 23" wide. This leaves me with predicament. I cant just build wider stand at 24", as then supports will not be sitting underneath the tank, no bueno. What would be easiest way to extend width of stand, so that I could have solid base for aquarium as REs template, but also enough room to fit wider sump underneath?

Thanks for the help

How many gallons is the tank?

How many gallons is the tank?

Approximately 110 gallons - 5 foot x 18" x 2 feet high. Made of acrylic.

I would over build it on the top support beam with 2 x 6 lumber.

I just made an extension to attach to the back of the stand, that is the same height as the bottom of the inside of the stand. No one can see back there but me, and if there is a plumbing leak, it will just drop into the sump.
