Oh...and when you say table salt do you mean just table salt? I have some Morton's that says "Salt, Calcium Silicate" on the back? Is this good or should I get some salt from a pet store/aquarium shop? Sorry for some pretty newbie questions.

Morton's is fine. Just avoid table salt that contains yellow prussiate or ferrous cyanide.
