Directions

Dosage / Instructions: To increase pH, add 5 ml (1 cap / 1 tsp) per 20 gallons of water. Check the pH of your aquarium water prior to dosing. Depending on the initial acidity of your water, several doses may be required to reach the target pH. Wait approximately 10 minutes, re-check the pH level before adding more Fritz pH Higher. If fish are present, limit pH change to 0.2 per day. If high levels of ammonia have accumulated due to low pH, raise the pH slowly to prevent generation of high levels of the toxic form of ammonia.
