pH Lower

To decrease pH, add 5 mL (1 tsp) per 20 U.S. gallons (76 L) of water.

1. Check starting pH with a pH test kit like Fritz Wide Range pH Test Kit.
2. Depending on the initial alkalinity of your water, several doses may be required to reach the target pH.
3. Wait about 10 minutes, re-check the pH level before adding more Fritz pH Lower.

• Do not change pH by more than 0.2 units per 24 hours when livestock is present.
• pH stability is more important to fish than a perfect pH. It is much better to change pH gradually, over time and in small steps. Our directions allow for that gradual change in pH to avoid stressing livestock.
