## 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 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.

Review: Excellent - I needed to lower the pH in one of my aquariums to create the ideal environment for my new German Blue Rams, so I decided to give this product a try. It worked wonders! With just a small amount added to the water, the pH dropped from 7.8 to 6.4 almost instantly. This product is absolutely incredible, and I highly recommend it to anyone looking for a quick and effective way to adjust their aquarium’s pH. It’s a game-changer!
Review: Perfect, solved our fish loss problem - Our waters pH from the tap is at the highest range on the test kits. At the time we were new to fish keeping and so we had problems with ammonia and nitrite, the additives we used lowered the pH to the lower range, but did not remain constant so it fluctuated from high to low, which when reading up on pH levels was very bad for the fish. From our research for our fish it seemed that a lower pH would be better for them, and to maintain it. This product has done just that, and remains constant at the 6.5 level between water changes which we do once a month and with that water change as per the instructions we add a little more. We had put off buying it for a long time because when reading up on pH it seemed difficult to maintain and could be more harmful to the fish if the levels did not maintain themselves and many believed it best to leave well alone, but we had suffered far too many fish losses and was desperate to try and get the tank into balance to keep the remaining fish alive and there is no doubt in our minds that using this product was the turning point for us, and we haven't had any more fish losses since using it, in fact the opposite we now have 25 babies born in the tank.

## 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 well as long as you don’t expect instant results.
*by G***A on 5 February 2024*

This is a good product, as long you don’t expect it to work over night. The way I found worked well was get containers for weekly water changes. Fill the containers the night before a water change, add all your water conditioner, and add this product. This also prevents shock, as the water becomes room temp, giving your thermostat less work to do, This stabilises the water in the containers to 7.0ph. Obviously it’s not an over night fix which some people think it is but give it 2-4 weeks of weekly water changes and you’ll have 7.0ph continuous. Hope this helps
