I love the natures ocean sand, bio activ I think it's called. Have it in both tanks and never had an issue. I have gobies and starfish and all sorts of stuff living in the sand bed. I have found that it creates minimal clouding. I have also tried and hated the carob sea brand. The particles size is all over the pace wit some chunks mixed in and it's ver fine and creates a lot of clouding, even after it settles. They gobies made a huge mess with it. I tore down a tank because of it and started over with the nature ocean.
I find the natures ocean the same price for the 20lb bag and a much better product overall. Not that this makes a difference, but I heard tanked tv show uses the natures ocean too. I use the Fiji pink color which is pretty much white/natural instead of the gold color,which to me looks a bit dirty.
Good luck!
