I bought some calcium powders a few days back. One has calcium with D3 and the other is just plain calcium. They are both phosphorus free but I don't know which one I should be using. My lighting set up is this: one 5.0 reptisun uva/uvb florescent fixture and a 100 watt basking bulb with a max basking temp of 85*F. I gutload my crickets with vegitables : carrots, lettuce, sweet potato and give them flukers all purpose cricket feed. Also my silkworms are gutloaded with mullberry chow. Should I be dusting silkworms too?
