In the early planning stages and have been thinking about my future build. I want a very large, well 200-300+gal in wall. Been looking at some build threads and don't see the answer to my question. OK, basically stand holds tank then a 2x4 wall is built above to come down to the tank. Then 2x4 part and stand are finished with drywall, etc. What protects the upper wall from salt creep and water? I'm thinking the only way is to have a eurobrace along that part of the tank so there will be glass below the 2x4 upper wall. Seems like all the monster in wall build threads that I've seen the tanks look frameless, can't see how that would work.
