I have never had a reptile before and I am planning to get a leopard gecko. I have done a ton of research but I am a little confused on a couple important aspects. First, I already know that for now I am going to have to use a LED light so I will need to supplement D3 (I will be getting a larger tank soon at which point I will be definitely be getting a UVB light), but should I use both calcium powder with D3 and Vitamin powder with D3 or just one? Also I have a heating pad already but I havent found a straight answer for if I need both the heating pad and a basking light (probably a very stupid question but I'd rather feel stupid then harm my gecko) One more thing......can I get suggestions on which powders to use please? Thank You!!!!!
