Hello,
Ok, as an adult, she only needs calcium about 3 times per week. Are you using a long tube bulb for your UVB or a mercury vapor bulb?
How old is your UVB?
If you have a mercury vapor bulb, calcium with D3 is not usually necessary if you have a strong bulb. However, lately they have not been very good. So, if you have a long tube bulb, hopefully it is the Reptisun 10, then calcium with D3, at 3 times per week, is fine.
If the urate dries, it will become harder & chalky with drying out.
