I would be very cautious about putting pond foam in my aquarium. My friend used foam as a background for her 220 and I helped her install it. It sure looks great in a tank. When it is fresh it has a hard shell feel and apearance, but this breaks down under strong lighting. After 8 months under hallides(submerged in saltwater) this stuff will have the consistancy of the green foam used for flower arangements. It was extremeley porous (like the flower arrangement foam) and a potential source of nutrients/toxins. I have seen this first hand on a friends tank that was just torn down. Only the areas of the foam left in complete darkeness have thier original shell/seal. Everything else is soft and easily scraped off with a fingernail. Another thing to note is that she had unexplained algea/cyano issues even with very careful husbandry, phosphate remover, and a top of the line skimmer. In addition the tank has been dry for a month and the foam still smells very funky. I would ask you to think very hard before you put this stuff in your tanks.
I am not trying to be a downer here there just aren't a lot of long term experiences with the foam out there and I know it will be part of the project at tomorrow's meeting.
