I was unsuccessful on the Cal monophosphate which surprised me so I went with the STP and have 100 lbs which will take me to the end of the line. The STP does inexplicably streak, even to the point of leaving what look like fingerprints at times. On a reanneal, it's dense and has great color. The trouble I see with the fertilizer grade is the tramp stuff.
It turns out your bones are largely apatite in the pentavalent state. A state you want to stay away from. Right now, I'm melting copper blues and they are so stunningly beautiful and so stupid easy.

Report back on the pot phosphate. It's a very interesting idea. That's not a terrible price although getting it back east might cost.
