55 to 90 gallon upgrade

Drilled 55 custom

Reefing newb
Hi, I'm upgrading from a 55 acrylic to a glass 90 gallon. I want to stay away from drilling & bulkheads with this glass. I don't care for the overflow box look. Do any of you remember long ago the picture, I think was in the DIY section of a pvc drain manifold set up? It had a "T" and a bunch of 90 degree fittings for each side of the back of the tank? I can't seem to locate the diagram, perhaps it was on a different website all together?? My aquarium freinds would appreciate any help, they grew up & need more room...thanks.
 
Are you trying to build a PVC overflow? Just google PVC Overflow and you will see tons of examples. I'm at work right now and can't access most of the pictures :(
