They must have Vitamin D3 in order to metabolize calcium to bone. UVB lights are not required and are dangerous when it comes to Albino Pacman Frogs. Use a Calcium supplement that contains D3 or a Multivitamin that contains it. You'll need both calcium powder and multivitamins.

Dust with the multivitamin once a week and dust with the calcium every other feeding or 3 Times a week, but not with both at the same time in the same feeding.
