Silica Sand

[tstevens]

Hi there,

I know this topic has been covered quite extensively but here goes:

Has anyone ever used Silica sand used in Pool Sand filters or Sand blasting for a DSB? I have looked at the granuals and they are definitely NOT sugar sized, more like candy sprinkle sized if that makes sense. Also the edges are definitely not rounded but suqared off and sharp.

Is this safe to use or will it definitely injure sand sifting critters like starfish, blennies, etc?

Can it be combined with some regular sugar sized aragonite to give it a better mix?

Is anyone here using this in any cpacity?

Thanks in advance!
