If I add ls to my tank - do I rinse it - if yes, how? When I started, of course, I had ls, lr and my tank ran for a couple months before I started with fish, so I didn't rinse anything. I can't imagine rinsing that super fine sand.
I rinsed my sand out in a 5 gal bucket for around 10 mins. This was of course before the fish as well. That way I wouldn't make the tank COMPLETLY nasty. You'd be amazed how much you can clean it...
