Nutrafin pH Adjust Up - pH Increaser safely increases pH using a plant-friendly, potassium-based compound. Potassium is also a common and important ion prevalent in Lake Tanganyika and is particularly beneficial to species originating from there. pH Adjust Up is very effective for use in aquariums containing alkaline-preferring species such as livebearers (mollies, guppies, swordtails, etc.), goldfish, African cichlids, brackish water species and others.


  • 1 drop per 3.78 L (1 U.S. gal)

* Use a Nutrafin pH Test Kit to determine the pH of aquarium water before adding product. After adding pH Adjust down, test pH to determine if the desired pH has been achieved. If you need more than 1 drop to reduce pH, this may indicate elevated Carbonate Hardness (KH) levels

Never bring the pH down by more than 0.5 in any 24 hour period.
