Hi All,

my water source is basically fresh from a mountain reservoir.

basically soft and neutral to slightly acidic. On a fresh refill, apx 400 gallons.

Becuase I think speciality spa chemical are grossly over priced
I use the following alternatives

Arm and Hammer Baking soda (sodium bicarbonate) PH up 1.99
Dri-aire crystals Calcium chloride Water Hardness 3.99
Epsom's salts Magnesium sulphate Stablizer 3.99


How much do I use you ask, 2 cups calcium, 2 cups Mag. Sulphate, 3/4 cup bicarb

compare these prices to what you pay at the store for the speciality brands that do the same thing
Before I researched what is in their bottles, I was paying approx 75 a year for the stuff.
this only leaves the chlorine and bromine for water sanitation, unfortuantely I have yet found a replacement.
