PMDD purity..

I think ive just found some pottasium phosphate.. but im unsire about the purity...heres the spec

Element :K. Compound: KH2PO4. Purity: 10. Unit 250g.

does this mean that its only 10% strength. ide be lost how to work out how much to dose without a phos kit and there pretty expensive thats the only thing i dont really want to get.

and this..

Element :K. Compound: KCl. Purity: 10. Unit 250g.

do i assume the same as above for the pottasium sulphate?
both are in powder form which is nice

can someone chip in please preferebly the boffs

I would guess the purity is rated on a 1-10 scale with 10 being the best.
