In l991 Jock Hamilton postulated the Hamilton Index system where total Alkalinity level be between 100 – 120 instead of  60 – 80.  The pH to be between 7.6 and 8.2 instead of 7.4 – 7.6. The benefit of running a higher pH is less use of a sanitizer with a more stable pH.  The Hamilton method has been used successfully for the last 12 years and is currently recommended by several Spa supply houses.

EcoOne is a product line that has widened the pH between 7.2 – 8.2 leaving the Alkalinity at 100 – 120.  With this system it is quite common to find that your pH rarely needs adjustment.  Calcium levels should be maintained between 150 – 400 ppm and never filling the spa with water that has gone through a home water softener.  Using Dichlor  sanitizer is highly effective and dissipates at a fast rate, so you can add the minimal recommended amount after using your spa and its gone by morning.  The use of Dichlor in this way ensures a clean bacteria free spa, with reduced exposure to chemicals during tub use.

No more itching, rashes, scum lines foam, etc, etc,.  I am a dealer for EcoOne and on my web site under “Instructions” you can get full details.  EverClearSpa.com

After doing extensive research on spa water conditioning my head aches trying to read through the various methods.  This is my effort to simplify spa maintenance.
