Effingham, IL | Hay Wilson in TX - 11/4/2012 12:37 Avail only protects an Anion from the Cation Calcium. It does nothing to protect the Cation Potassium from another Cation.
Hay's statement above is very important. Sadly, 99% of those selling the product do not understand how the product works, thus it is recommended in conditions where it will provide zero benefit.
