Roy, Is there any nutrient advantage to turface? Is it lighter than an equivalent volume of gravel? As you know I need to add substrate to my tank, so if someone can convince me this is a good option, I'll take a bag. Mostly I need something that Doodles can't doodle plants out of (Doodles the 5" hoplo cat).
