Calcium carbonate

[Kerry1968]

If you're looking for a cheap calcium supplement for your frogs (sorry, I got confused on the way through this thread and not exactly sure that's what you're looking for) you can crush cuttlefish, the white stuff you give to birds for calcium. I use this and in fact didn't even pay for it, I picked it up on a local beach, washed it and use my pestle and mortar to grind it to a powder. You can usually buy it cheap at pet stores.

Thanks for that Kerry I didn't even think of that I'll have to try it sometime.
And sorry you got confused I worded it very badly. lol
