I use it. It's in my 200g reef, and my 125 fowlr. No issues.
Need to rinse it very well, it's a lot of dust. I spent several hours rinsing it in my driveway. I love the white color, my gobis & conch snails keep it turned over well.
Also I believe it is silica sand. Don't fall into the rumor that silica leaches from silica sand it is simply not true. I have a test kit for silica & all test always indicate spot on or slightly lower than it should be.
I have over a dozen wrasses, a bunch of conchs, 2 diamond gobis that sift all day, plate corals, scoly, acans, chalice. Never issues from sand. Any other specific inverts your worried about?
I can't keep clams but I doubt that's due to the sand. I've had them in rock work& still failed. My kole tang poops this sand out continually, I would think if it was sharp, that would cause problems fastly. People over think things.
It's pretty fine. If it's not we'll rinsed, you'll have problem. I rinsed mine in a large flat plastic drawer. I rinsed it until the water stayed clear even after mixing up the sand. So I was left with only the heavier pieces. I have 2 wp40 & 2 wp25 & a koralia pointing down. The wp all point upwards. No issue with it blowing around. I have a damsel that likes to make a sandstorm clearing under rocks with his tail, but it settles fast.
