## Overview

API PROPER pH 7.0 Freshwater Aquarium Water pH Stabilizer is a scientifically formulated treatment that sets and maintains a neutral pH of 7.0 in freshwater aquariums without live plants. It detoxifies tap water by removing chlorine, chloramines, and heavy metals, ensuring a safe, stable environment for tropical fish.

## 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. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium. API Aquarium Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your tank. Make sure to use all products as directed in order to ensure the best results.

Review: works well - this product works great ph in my area is naturally low so one a week i add this gets my ph were it needs to be great price on line as compared to the pet store
Review: Amazing!! - I have had an aquarium in my house for over 30 years, and where I live, have always struggled to control the pH of my tank. The water in my area just inherently has a high pH. I have purchased various products to lower the level, but while they work initially, they do not maintain the level beyond a day or two. I was understandably skeptical that this product would be any more effective, but it has turned out to be amazing. The pH was immediately corrected as soon as I put the powder in the tank, and it has stayed constant in between water changes. It causes no change to the clarity of the water and has no detrimental effect on the fish. Definitely recommend.

## Questions & Answers

**Q: Mine did not come with a scoop or a seal. 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.

### ⭐⭐⭐⭐⭐ Works great for me.
*by C***. on May 15, 2012*

I found this product to be very helpful in maintaining my aquarium at7.0. Don't expect this to be a miracle cure that keeps your tank perfectly at7.0 forever. This is meant to be something that helps you to avoid sudden shifts in pH, maintain a relatively stable pH between tank changes, or helps to bring your pH back to 7.0 when something altered it. There really is no true way to keep an aquarium exactly at 7.0, and if the pH is changing rapidly that would be an indicator that there is something wrong with the overall water quality of the aquarium. Simply forcing the pH to remain at 7.0 doesn't mean water changes can be skipped or that overfeeding won't harm the water quality; all it really means is that the pH is within the ideal range of 7.0. I do bi-weekly water changes in my 40 gallon tank, and between changes I use this to maintain the pH at or around 7.0. My pH will drop to about 6.7 and this brings it back to 7.0, and then by the next water change it will be about 6.7 again until I change the water. This isn't meant to keep your tank at 7.0 forever, but it works great to help maintain a healthy aquarium. If you find that this doesn't dissolve in the aquarium or it leaves the water cloudy you can dissolve it in water before putting it in the tank. I don't mind the cloudiness because when used in the recommended amounts it only stays cloudy for about 15-20 min as it dissipates into the water. I really don't see any reason why this would harm your filtration media when used properly. If anything the particles would get stopped in the filtration media which reduces the cloudiness as it continues to dissipate.
