Good advice Bruce. Repashy makes a high quality supplement as well. I often use it as the vitamin because with the Vit-All you have to gut load feeders with it to give it to the frog. The Miner-all calcium is easy though..you just dust the feeders as normal. Every other day is fine, but with the Repashy especially I would go every third feeding. As my females got full sized I slowed the calcium input to once a week.

Repashy C+ is a little expensive. One good thing about it is you can usually pick it up at your local pet shop (LPS) so it ends up about the same price. You have to order the Miner-all (it lasts forever though) online.
