I use the ICB leopard gecko dust. It is designed to be used with every feeding and has the proper proportions of calcium and D3. So I just keep a small dish of calcium free D3 in the tank. I got her back in the first of December and she seems to be active and healthy. I find the ICB leopard gecko dust to be much easier because I can use it with every feeding instead of having to keep track of when I used what supplement.

I keep mine in a 20 gallon tall fish tank and she has done great in it. I got her as a baby and has not shown any signs of stress. The important thing is to have at least 2 hides. One on the warm side and one on the cool side but it is better to have more. Hope this helps.
