Ok.. I have read every post I could find on here, and about 75% of the ones that google returned from varied search queries.
One simple question I have has NOT been fully answered.
I know to use 100% Silicon.
I know to use Styrofoam.
My question is. Is quickrete Saltwater Safe?
If Not, what else could be used to get the Rocky / Sandy look??
Could I just coat the 'wall' in epoxy / silicon and coat it with playsand, or what?
I know what I want, i have a design prototyped in 3dsmax already. I have a fair amount of artistic ability..
I just need to know whats 'SAFE'.
All that i have found to date with saltwater mentioned seem to be in the context that saltwater was used to 'Cure' the background, but was soon replaced with Freshwater.
