Hi All,
I managed to get my hands on some K3PO4 (Potassium Phosphate) and I'd like to make a reference solution for dosing into my tanks, 50G and 15G respectively.
However, I found that the Potassium Phosphate that's used around here is KH2PO4.
If I followed the reference solution in the sticky, I'm worried that I might be dosing 3x the amount of K into my tanks.
From the EI pages :
(+ or -) 2ppm of K+ is pretty reasonable.
(+ or -) 0.2ppm of PO4 is pretty reasonable (?)
K+ range 10-30ppm
PO4 range 1.0-3.0 ppm
I know that EI has proven that we can dose excess without fear, but my inability to calculate is stopping me (thank god)
Appreciate if anyone could 1) tell me if K3PO4 is usable, 2) how to make a reference solution.
*reference solution will make it easier for me to dose as I have a syringe.
** I only managed to find out that the molecular mass of K3PO4 is 136.
Thanks in advance!!
Regards,
Ryan
