Unhealthy obsession?
Should be noted Tahitian Moon Sand is a glass by product so if you have anything that digs in the sand, corries, loaches etc. be aware they can suffer damage to barbells mouths and gills. 3M colorquartz is just a ceramic covered silica sand so as others have stated completely inert but I heard they are not making it any longer as the custom pool biz must be taking a hit these days. Good luck, I tried for black and ended up going for regular playground sand. At $5 for a large bag you can't beat the price.
