Expanding foam

[Nano_Man]

Hi everyone
Anybody use it for display purposes
Ii know you can get black reef safe so I would love to see a picture of a tank that it has been used in
Could be a way of making a stunning scape with out too much Rock
Your thoughts would be great on the subject

I know people have used it for their back walls before - I don't think I've seen it used for other parts of the scape though:

The entire overflow cover was foam. Not black the standard great stuff window and door. This tank was taken down when I moved across the country but was running for about 3 years.

It is best to coat the entire structure in Marine epoxy. I used West system. The other thing to consider is do not underestimate how buoyant the foam is. Many large pieces of rock still kept it at neutral buoyancy.

Here is where I detailed the construction.
