I read through those threads and a bunch more i found googling. And I am a bit put off by the Cal+ and I decided that I would prefer the versatility of having separate dusts. Anyhow, I was also wondering about using Miner-All Indoor as my source of D3. It has 4,400 iu/kg of D3 whereas Rep cal has 400,000 iu/kg of D3, that's about 1/90th of rep cal. Therefore, I could dust with minerall indoor 7 days a week, and that would be less than 1/6th of the dose of D3 when using Rep cal once every 2 weeks (assuming equal amounts of the powder are ingested by the cham w/ each dusting).
So, I'm now wondering if using Minerall outdoor 3 days a week, Minerall indoor 3 days a week, and a multivitamin like repashy SuperVite twice a month, would be a good schedule for a juvenile.
