Different fishes need different pH levels to stay in healthy environment . stable pH is vital to the health of aquarium livestock and efficiency of the bio-filter. AQUANATURE pH + are concentrated, safe and easy-to-use formulations that adjust and maintain the correct pH for freshwater aquarium. With pH + , the pH may be increased to a desired level for aquarium inhabitants. USAGE Check the pH of aquarium water with ph test kit. To raise pH, add 1 ml. for each 10 gallons of aquarium water. Take another pH reading before adding another dose of pH +. Some fish may be sensitive to pH adjustments so wait for 24 hrs then gradually dose ph +. DIRECTIONS Shake well before use. Push 4 times Equal to (5 ml) per 50 US gallons (190 L) of aquarium water. Depending on the initial acidity of your water, several doses may be required to reach the target pH.
