This product will increase the total
alkalinity (sometimes called buffering capacity, carbonate hardness, or KH) of
freshwater aquariums, there by providing a stable pH in the system. A test kit
which measures alkalinity is absolutely necessary for use of this product. This
product should be used prior to adjusting the pH.
pH Stable does not promote algae growth, phosphate and nitrate free, and safe
for freshwater fish and sensitive plants.
Add 1/8 tsp powder to a pint of tank water and mix well. Disperse this amount
around the tank for every 20 gallons of tap or tank water to lower pH.
