Why is it recommended to not operate the ionization system if the alkalinity is below 50?
This is due to the relationship of Alkalinity and copper. Copper ions can be more toxic to fish if the alkalinity is below 50. A good range of alkalinity level is between 80-120 mg/L (ppm). A maximum suggested range is between 50 – 250 mg/L (ppm). Baking Soda can be used to raise low alkalinity. Adding 0.15 pounds per 1,000 gallons will typically raise the alkalinity by 10 mg/L (ppm). Raising the alkalinity should not be done all at once, but over a period of days.
