i have been looking at things about adding calcium to the saltwater tank now i have a question about this. it might seem a little odd but i was looking at the make up of a cuddlebone from the cuddlefish it has all the elements needed for the tank if say one was to powder a cuddlebone and use it like calcium powder would it work.

With a tank your size, there really isn't a reason to add calcium, unless all you have is sps corals in there. Weekly water changes will keep your calcium balanced for you.
