are there any dangerous sands

it is VERY attractive and was only 2 bucks at menards for 50# as opposed to the $1/1# the pet store wanted for "aquarium sand" this sand is way more attractive than any other sand I"ve seen

it is VERY fine and light tan, likje a desert or the ocean, it is absolutely gorgeous, if that is a good enough reason
 
alright, water test showed .5 ammonia and high Ph (typical to our area) so I don't know if i twas just chemical shock or whatnot, I'll try to add fish again sometime tomororw
