Out of curiousity, does anyone have valid documents of gut impactions from sand? I did some searching and found nothing on actual impaction from sand, I did find alot of sites where it claims impaction but Im a guy that likes proof. I've used sand for years and still do and Ive honestly never had any bad luck with it, though it did turn my sulcata purple when I used calci-sand.
Nowadays I use sand from a local creek.
Id love to see actual documents.
