We now have a new size on the Instant Ions, 250ML, which is enough for a year if you take good care of your water's pH.
It is concentrated CuSO4 solution that makes your water clear and sweet, without harsh chemicals. This is the best water and is raved about by spa owners.
We are the original developer of all the ion systems for spas. It is our research that led to others realizing the power of ions. Our testing of this using bacterial culturing and severe testing proved this is one of the safest and most beneficial way to treat spa water. It is our data used in computer programs when you take your water into a pool store for testing. This is the real deal on ions in spas.
