A few people have had it for a few months with cories with no noticed damage, but it's not worth putting it in a new set up knowing the risk.
It's also full of silicates (glass) and can leach in the water causing diatoms.
If that gravel is CaribSea, it might be okay.. I'd double check the website, but last time I was there all their substrates had a big red X in the "bottom dweller friendly" category.
I am a little confused by that ^^^ The highlighted areas. It was CaribSea. Is that an alright brand then for Corie's, or not? From the picture, it appears like real heavy sand kernels?
