Hi all,
It wouldn't offer you any control but could use <"Oyster or Cockle shell chick grit">, it is very cheap or you might be able to PYO shells?

I must admit that was more of a potassium (K) addition than I was expecting, but I can see that the calculation is right.To get 2dKH i need add bout 3,5g potassium bicarbonate to this, it's another 27ppm.
