Installing a 3D background in a running tank?

[Coxey81]

Hi, I purchased my tank used and have had it about 2 years. Since it came with livestock I never really got a chance to consider things like a 3d background.


I've seen some made with spray foam, sand, gravel, and spray paint that reportedly completely reef safe as long as you let them completely cure.

I would definitely do my on research on that before doing it. But even if I made it I'd have to attach it under water.

Any ideas on if this could be done or has anyone done it? I thought about plastic coated magnets, but concerned about dead spaces etc behind it.

From my experience, If you see someone else do something, reaching out to them can be helpful to see how they perform the task. Great idea.
