I did a search and one got one result for freshwater. And I read it can harm some corals in saltwater. Iv found this brown Aluminum Oxide on ebay, and it looks like the ideal substrate that I would want. Google doesnt come up with anything much for freshwater, only salt. So, does anyone here have Aluminum Oxide in there pics, have any info on it, and pics?
Heres what I was looking at
