API® PROPER pH 6.5 automatically adjusts and stabilizes the pH at 6.5, and also removes chlorine and heavy metal toxins. It works best with trout, discus, and angelfish, and contains electrolytes to reduce fish stress. Can be used when setting up the aquarium or when changing the water.

• Add one scoop per 10 gallons of aquarium water.
• Repeat the dose when the pH test indicates a change in pH of more than 0.2.
