I reconstitute with Magnesium Carbonate, Calcium Carbonate, and Potassium Carbonate.

That way I can precisely raise the GH and KH and have a known amount of Potassium. Another great benefit from using carbonates is that you do not introduce andy Sulphur (from MgSO4) or Chlorine (from KCl or CaCl2).

Few days ago I made 20 gallons of water for a wild betta that I'm importing from Thailand. The RO I made is 2GH, 1KH and has 5 ppm K.
