I've been feeding Taliesin black soldier fly larva from Syntom. He loves them and I love how convenient they are. That being said the bsfl from Syntom have a higher calciumhosphorus ratio (don't have the table with me but I know it's higher than 1:1). Because of that I'm afraid to dust them with calcium because he shouldn't really need any more calcium.
That being said how can I make sure he's getting enough D3 without risking hypercalcification? I have a t10 tube light in his tank but I dont think that will be enough based on what I've read. Any thoughts?
I heard that you don't need to dust them. I just started feeding Edward phoenix worms, because he will no longer eat crickets and he loves them. I feed phoenix worms as staple with veg/greens and also butter and wax worms on rotation a few times per week.
I don't bother dusting the BSFL but you can if you want to. The D3 is synthesized by getting adequate UVB so as long as that is at the right distance and a relatively new bulb that should be fine. A T5 10.0 (with reflector) should be about 12-14'' away from the basking area and a T8 10.0 bulb (with reflector) should be about 6-8'' away from the basking area. The T5 will produce UVB levels closer to natural sunlight and is more likely to allow natural D3 synthesis than the T8 is.
