I constructed a foam rock wall using eggcrate intended to cover the back of the aquarium and also a part of the bottom. I used the landscape touch ‘n foam. After everything had dried, the back side is now a little warped with the top bending over due to the weight of the rocks. Because the structure has both the wall and the floor, the wall needed to dry vertically with the floor resting flat on the ground. The height of the wall is approximately 28†tall with the floor part being approximately 10â€Â. It would have been preferable having the back wall resting flat on the ground and the floor being vertical, but since I had the heavier rocks on the floor, this wasn’t feasible. I have attempted to straighten it up as much as possible. My question is that when I affix it to the back wall of the aquarium using DAP aquarium silicon, will it be strong enough to hold over time. Currently, I believe that the rock wall sticks out about a half inch to one inch at the top from the aquarium back. When letting it adhere to the back, I will be somehow clamping it to hold it against the back of the aquarium until it has fully dried. I welcome anyone’s comments.
