Calcium Spray Vs powder

[lil_amie]

Hi everybody. I have a 6 month old beardie that I have been using a calcium + D3 powder for cricket dusting. I recently saw at the pet store a liquid spray calcium and a vitamin spray. I'm just wondering if the liquid form is as good as the powder one? Since I always get powder everywhere

Actually if your using a GOOD UVB bulb, (reptisun 10.0) you do NOT need to use the calcium with D3.. you will actually O.D. your dragon since they produce thier own D3 with the correct UVB exposure.  If your using a lower quality bulb, then the D3 is still recommended, however, why use and settle with a lesser quality product??

I'm currently using the mega ray bulb that has the UVB and heat source in one. Should I get a new calcium powder without the D3 then? I don't want to O.D my dragon.
