play sand is better than filter sand.
Filter sand tends to have sharper edges.

I like this because its more course. Not as fine as playsand

If it's just Silica sand then it should be fine as it's inert, same as playsand just a larger particle size. Double check there is nothing added to it and that it is just pure silica sand, if it is then give it a good wash and you should be fine.

I won't take a chance with it because i have sharks and wouldn't want it cutting them.

yip, filter sand is a bit too rough for certain fish like sand sifting gobies and wrasses that sleep in the substrate.
