I have a water softener system on my full house. I would be using this water for the pool. I use Potassium Chloride as the softener salt instead of Sodium Chloride.
Is there an issue with having Potassium Chloride instead of Sodium Chloride?
I know that the salt turns into ions in water, so you would still end up with the Cl- being available for the SWG to use. From what I understand KCl requires 30% more to get the same Cl- ions when compared to NaCl.
