pH - HI

• Increases pH level
• Reduces acidic pH level
• Contains no phosphates
• Easy to use

1. Use Won Brothers PRO-HOB test kit to determine the pH of water.
2. To raise pH, add 2 drops of pH-HI for every gallon of water.
3. After one hour, retest the pH of water.
4. Repeat steps 1-3 until desired pH level is achieved.

1. Before using pH-HI, determine the adequate pH range for your type of aquarium.
2. pH should be tested regularly to maintain a stable level.
3. To avoid pH shock, do not increase pH value more than 0.3 degree within 24 hours.
4. Water with buffering capacity may revert to old pH levels within 24 hours.  If this occurs, repeat the treatment process to maintain the desired pH levels. Or use Won Brothers BUFF-SOL to adjust and stabilize pH.
