## Description

Product 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 6.5 Freshwater Aquarium pH Stabilizer automatically sets and stabilizes the pH level in freshwater aquariums to 6.5 which is perfect for Tetras, Discus, Rasboras and Angelfish. API PROPER pH 6.5 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. For almost 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. At API, we understand the rewards and relaxation of fishkeeping because we have a passion for fish too.

## Questions & Answers

**Q: I have just recieved it and it says can not be used with Aquarians with live plants? Anyone else tried it with live plants?**
A: My aquarium contains Marimo moss. This is not affected by ph 6.5. I really can not see how this product can affect live plants. I would chance it. Your fish welfare takes priority. Good luck.

**Q: Can you use this with 'tap water conditioner' as they both remove chlorine and detoxify heavy metals?**
A: My husband uses the ph 6.5 and puts tap water in with this before doing a water change and its fine

**Q: my tap water is 6.2 i assume this will raise it? also do i still use tap water conditioner with this as the description says it also removes chlorine?**
A: Yes it will and I always use both and my tank is well established with healthy fish and plants

**Q: Can you use direct into ro water**
A: No don't put directly in.  Dissolve in hot/ boiling water and then mix some existing water with it before adding.  I use whenever I clean my tank out, take some buckets of water out and then replace water with water conditioner and API proper PH
