Re: marine sand I'm sure you didn't mess up  It is non-toxic and although I searched their site for an msds sheet to see what it is made from. I could find nothing. You could call them and ask or you could look on the bag and see if it lists the contents. At best it is an aragonite based sand at worst it is silica based. Either way you are not hurting anything.
