Any one no if there is any tipe of Foam Spray that is Reef safe. I would like to make a Rock wall with some items laying around the house. But I need some type of foam that would be reef safe.
Sorry, don't remember exact name, but Home Depot has a foam spray for use in ponds and waterfalls that is 'safe', but there may be some other problems with it's use. do a little research, before installing any foam walls.
