Has anyone out there used the potassium chloride water softener to raise their potassium levels. I used NOW potassium chloride in the past and was useing a substantial ammount on my 40g, like a jar every 3 months. I'm running vodka/neo zeo and it gets used up at a decent rate. Now I have a 180g and would like to save $10-15 a month by useing the pelets. Just wanted to check if anyone else has used them, from the MSDS they look to be pure KCL and of course are food safe. Definitly won't be trying anything with some aditional advertised properties like rust remover etc.
