There is a lot of conflicting information out there.
I don't go by what books say or what others say......
I go by experience and what has worked for me. I've been working with leos for over a decade and have found my nutrient/vitamin mix perfect(for me).
I buy a container of RepCal Calcium Enriched with D3(Phosphorus Free) and I buy a container of RepCal Herptivite Multivitamins........one should have a pink label and the other should be blue.
I then create a 50:50 mix of the two supplements....if both containers are newly purchased and unopened, then there is no need to measure, I just dump the two containers into one large container or baggie.
I then dust every cricket that enters the geckos' enclosures with that mix.
I have never had an issue with Hypercalcemia, Hypocalcemia, vit def. , or what have you......just healthy geckos that breed for me.
