I just got my first 5 leopard geckos, ordered them today I have been doing a lot of research about them but everywhere I go gives me something different on this particular subject.... Half of the websites say to use calcium with D3 mixed with a multivitamin and leave that in a dish at all times. The other half just say to leave pure calcium with NO D3 (half of those say with a multivitamin and half dont say anything about a multivitamin).

So what is wrong with the D3? I know that it helps them absorb the calcium, but why do some say that you shouldnt use it except for once a month and others say leave it in the dish at all times?
