API pH Up Freshwater Aquarium Water Treatment
Help safely and quickly raise the pH in your freshwater aquarium for more alkaline water conditions with API pH Up Aquarium Water Treatment. Different fish need different pH levels to stay healthy. For example, most freshwater fish thrive in levels between 6.5 and 7.5, but Cichlids and crustaceans require higher pH levels between 7.8 and 8.8. Levels that are too high or too low can cause stress, illness and death, so testing is crucial to the health of your fish. API pH Up Aquarium Water Treatment is designed to raise pH in water that tests at an undesirable level. It is fast-acting, colorless and easy to use. It will not cloud or color aquarium water and because it's phosphate- and nitrate-free, it will not encourage algae growth.

- Determine the pH of aquarium water with an API pH Test Kit.
- To raise pH, add ½ teaspoon (2.5 ml) for each 25 U.S. gallons of aquarium water.
- For larger aquariums, add 1 teaspoon (5 ml) for each 50 U.S. gallons of aquarium water.
- Take another pH reading before adding another dose of pH Up.
- Some fish may be sensitive to pH adjustments greater than 0.2 in a 24 hour period, so changes of this magnitude should be done with extreme care.
What does API PH UP do?
API PH UP is added to water to raise pH levels, making water more alkaline.
Can I use repeated doses of API PH up?
Yes, you can use API PH UP once daily in your aquarium, but you should always check the pH between doses.
Can API PH UP be used in marine aquariums?
API PH UP will not cause any harm to marine aquariums, but it is designed specifically for fine-tuning pH, and is not strong enough to have an effect on marine aquarium levels.
Can API PH UP be used with live plants?
Yes, API PH UP and API PH DOWN are safe for live plants.
Does API PH UP also increase KH?
No, it does not.

More good product for the money
By Ferdie4 on Aug 13, 2018
I usually get a small bottle of this for the same price. This will last much longer and helps keep the PH up in my tank. Even with frequent water changes & cleanings the PH needs help.

Good Stuff
By Catfish143 on Dec 14, 2017
This stuff really works. Be careful, read and follow directions. Don’t over do it. Raise the pH slowly for your finishes benefit. But API’s “pH UP”” will do it.

Ph up works really well for my cichlid tank. Chewy has the best price that I've found and the customer service is great!
