I want to use sand substrate for my next setup and remembered threads on this forum re: Southdown. read through the old threads and remembered that I have a bag of Play Sand I bought for my little one's sand box and thought it might be Southdown (btw
: For those with kids, stay away from this sand as play sand--it's like playing in flour, my daughter comes out looking like Casper the friendly ghost).
At any rate, and my Q: The bag clearly says "NOT for Aquarium Use" Any thoughts? Is it safe? Says sterilized, silica free, 100% natuaral, etc.
