from the attached picture I'm sure you can see my need for a background. My tanks is a 210 gallon, 30" high. No one that I can find, makes a 30" high background so I decided to make a live rock wall between the overflows. My plan is to get some live rock rubble, glue them together using some sort of water safe epoxy. Drain 1/2 the tank into garbage cans and glue the wall to the glass. Anyone ever try this? Any tips? Also any suggestions as to some good quality adhesive?
Thank you for your time.
