I currently do it once a week but i'm not sure if i should do it more than that. Before you ask i usually give her 2 crickets because that's all she ever eats.
I use Rephasy so I dust my feeders everyday. When I used to have calcium, calcium D3 and vitamins I used to dust with calcium every feeding, vitamins twice a week and D3 one a week.
crickets have way too much phosphorous compared to their calcium content. dust them *every* feeding or you're risking MBD. the dust will raise the calcium:.phosphorous ratio to the proper level which allows the calcium to actually be absorbed.
When you dust with vitamins do you still dust with the calcium supplement? Like do you just dust the crickets with both? Or some crickets with the vitamins and some with the calcium.
Also, the calcium dish inside the geckos enclosure is that without D3, correct?
