I picked up a 100lb bag of white blasting sand for $25 to use in my 75gal. I was wondering if anyone has any experience using it. It is really fine almost like sugar. I used a little bit of it in a freshwater nano and it looks great. I'm just concerned about long term use. It's been in my nano for about a month now. Do you foresee any issues? Here is a pic in my nano. Your input would be appreciated.
