I was wondering how often I should give chameleon calcium with d3? He has a exoterra 5.0 UVB bulb and my bedroom window gives enough uv light in. Also how often should I give my Cham zoo meds reptivite without d3? I normally give him these every other Sunday, like this Sunday I'm giving him his reptivite then next Sunday ill give him d3, just curious on how much I should give of these and how often? I dust with normal calcium powder daily.
