I use a hob
overflow on my 56. Does the job. But first things first. What size sump where you thinking? What kind of room do you have available? Will it be under the stand? Basically your sump is a place for you to put all of your equipment ( sump heater etc..) it also serves as filtration by adding media, a refugium etc. You don't need a refugium but they are helpful. But as for pumping it, it's really simple. You can do it yourself with PVC
or tor LFS
will have the correct tubing to fit the overflow box and one for whatever size return pump you get.
