It detoxifies tap water by removing chlorine, chloramines, and heavy metals, ensuring a safe, stable environment for tropical fish. Ideal for new setups, water changes, or pH adjustments, this 8.8-ounce container offers easy dosing and trusted performance from a brand with over 50 years of aquarium care expertise. ## Description pH is the measure of acidity of water, on a scale ranging from 0 to 14. A pH of 0 is the most acidic, while a pH of 14 is the most alkaline. Water with a pH of 7.0 is considered "neutral". Different geographies have different tap water conditions with different pH levels, while fish require a specific pH level to thrive. API Proper pH 7.0 Freshwater Aquarium pH Stabilizer automatically sets and stabilizes the pH level in freshwater aquariums to 7.0 which is perfect for a mixed variety of tropical freshwater fish. API PROPER pH 7.0 Freshwater Aquarium pH Stabilizer also removes toxic compounds from tap water such as chlorine, neutralizes chloramines, detoxifies heavy metals, and adds electrolytes, making tap water safe for fish. Use this aquarium treatment when setting up a new aquarium, adjusting pH, or changing water. pH in an aquarium can fluctuate due to fish waste, uneaten food and addition of tap water. It is recommended to test water for pH weekly. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium.

Should I be concerned about the lack of seal? If not, how much does the scoop hold?** A: Mine came without a seal too. I stuck an unused chop stick in the container and found the scoop was in there at least. So I dumped some out on a paper plate and retrieved the scoop. Next time I buy this I will open it at the pet store to make sure there is a seal though!! **Q: Can i use this with all kinds fresh water fish** A: No. Use this only with fish that should have a ph of 7.5. You can kill fish if that is not an appropriate ph for your fish. **Q: How much would I use for a 1.5 gallon beta tank?** A: Honestly, I would use an altogether different product as opposed to this one for a 1.5 gallon aquarium. Ideally, use a liquid based product, as it will integrate with the water chemistry a bit better. That being said, if this product is the only option you have available at present, I would dissolve a small portion (a quarter of a teaspoon, if not less) of the product in a container with some of the water from the aquarium in question. Once the product has dissolved completely, add it to the aquarium and wait a couple of hours before conducting a pH test. Also remember not to try and "chase" the pH,-(or attempt to make it "perfect" as multiple changes to the water chemistry over time will have seriously detrimental effects on your aquarium's inhabitants. Hope this helps. Good luck. **Q: Why can it not be with live plants** A: API PROPER pH 6.5, 7.0, and 7.5 bind to some trace elements which are needed as nutrients by live plants. Therefore, we do not recommend using these API PROPER pH powders with live aquarium plants. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Product to Control pH *by L***Y on August 7, 2026* Always use this product.
