I have read many threads on R2R discussing black substrate manufacturers with magnetic properties of the "sand" being one of (if not) the biggest concerns. I come from a FW background and I have used the National Geographic brand substrate in many of my tanks; both with artificial and live plants.
I haven't seen much discussion on this brand; link HERE. Has anyone used this in a SW and/or Reef setup? I have placed my magnetic algae scraper directly on this substrate before and none of the sand has stuck to it... thoughts anyone?
