    Ok so I'm about to get a 60 gallon tank from a friend of mine. (Life pro tip. Don't off the wife she'll make you give your tank to your friend) I found the blasting sand for sale at a northern tool but it's medium grit. Will that be too rough for pygmy corys? If it is will pool filter sand be ok for them?

    Either would work. I have a mix of pfs and 20/40 (medium grit) black diamond with cories with no problems.

    I started out with pfs, but when I got albino cories I bought some black diamond and mixed them together so the sand would be darker, i really like it.

    Medium grit is perfect for corys you should be fine.
