Using Calcion-P as 2 part

[Groundfury]

Does anyone use Brightwell's calcion-P fro there Cal in 2 part? I am trying to find out how much I need to add to make a gal of stock solution. If my numbers are right I need a little over 400g to make a gal of solution at 37,000 ppm. I am matching the PPM off of using Dowflakes. Any help would be great.

400g seems like a lot, but i mix mine in a bottle of zephyr hills. 80 grams mixed in a bottle of zephyrhills is my stock solution. 5ml of that solution raises the calcium in my 47gal system 25ppm.
