API Proper pH 6.5 Freshwater Aquarium pH Stabilizer sets and holds pH to 6.5 and resists pH rebound. pH is the measure of the acidity of water, on a scale ranging from 0-14. ApH of 0 is the most acidic, while a pH of 14 is the most alkaline. Water with a pH of 7.0 is considered "neutral". Along with keeping your pH at the correct levels Proper pH 6.5 also removes chlorine, neutralizes chloramines, adds electrolytes & detoxifies heavy metals in freshwater aquariums. It is perfect for soft water species including Tetras, discus, Rasboras, and Angelfish.

• Sets & stabilizes pH to 6.5
• Removes chlorine
• Ideal for Tetras, Discus and Angelfish
• Use when setting up a new tank, adjusting pH in an established tank, and water changes
