Silica Sand?

  • We are currently upgrading MFK. thanks! -neo
Thats not pool filter sand, although I think PFS is also silica. I would just use PFS to be safe.
 
the "Use only as fireplace floor decoration" doesn't sound too reassuring

i bought some other silica sand from home depot, works good, very smooth, but i think it is too fine. it gets sifted easily and i tend to siphon a good handful during water changes
