I checked out the foam thing. They use the same method to prop up the mangroves at my aquarium. That seems to be a-okay wil. Concerning the macro, I have some in my tank and it just seems to get in the way a lot unless you have it properly anchored. Even then, it does become a nusiance more than anything. If you want to do macro I would suggest using a small amount. But then again it's your tank.
