Help set and stabilize pH levels with API's Proper pH 7.0 Aquarium Water Treatment. Different fish need different pH levels to stay healthy, and most communities thrive at 7.0. Levels that are too high, or too low, can cause stress, illness and can even lead to fish loss. This API water treatment is formulated to modify and maintain pH for several weeks while neutralizing harmful chlorine and toxic heavy metals. It also contains soothing aloe vera and electrolytes to help heal damaged tissue and help prevent electrolyte imbalance. Best of all, it's easy to use and fast dissolving, making it ideal to use during aquarium setup or water changes.

Key Benefits
  • Formulated to help set and stabilize pH at 7.0 for fish who thrive off of this level.
  • Helps to remove chlorine and detoxify heavy metals, for a more habitable environment for your finned friends.
  • Specifically designed to help modify and maintain pH levels in freshwater aquariums.
  • Easy to use, fast dissolving and is ideal to use during setup and water changes.
  • Contains aloe vera to help heal and regenerate damaged tissue, plus electrolytes to help prevent electrolyte imbalance.

Do not use in aquariums containing live plants.

Test your aquarium's pH level with API's pH Test Kit, pH Test and Adjuster Kit or pH Test Strips.

Remove enclosed scoop. Shake well to mix powder. Add 1 scoop for every 10 U.S. gallons of aquarium water. Repeat dose when pH test indicates a pH change of more than 0.2. Do not use in aquariums containing live plants.


What do API PROPER PH powders do?

API PROPER PH products are pH buffers. They set the pH of aquarium water at a particular level, and also function as a dechlorinator. This means no additional dechlorinator is needed when using these products to treat water.

I used API PROPER PH and my water has gone very cloudy. Is this normal, and is the cloudiness safe for my fish?

The cloudiness that can be caused by API PROPER PH powders is harmless. It usually settles on its own in 24-48 hours, but the use of API ACCU-CLEAR may be used to improve it. This cloudiness occurs when API PROPER pH is in used in water with high hardness levels, and is caused by the hardness minerals coming out of the solution. To avoid hazy water, we recommend reducing hardness levels to 100 ppm CaCO3.

I am trying to lower my water with API PROPER PH, but it remains high. Why is this?

Normally, one dose will set the pH. However, some tap water sources used in freshwater aquariums are very hard or alkaline and are strongly buffered at pH 8.0 and higher. In this case, it may require two doses of API PROPER PH to overcome the natural buffers and set pH to a desirable level. In this situation, it may be advisable to soften the water first.

Is API PROPER PH safe with invertebrates and plants?

API PROPER PH is safe with invertebrates, but the powders in 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.

Is API PROPER PH a phosphate buffer?

API PROPER PH 8.2 is a bicarbonate and carbonate buffer, and contains no phosphate. API PROPER PH 6.5, 7.0, and 7.5 are phosphate buffers. Phosphate buffers are the most reliable buffers for freshwater aquariums. They are non-toxic to fish and easily “lock in” the pH for extended periods of time.

Do phosphate buffers stimulate algal growth?

No. Phosphate buffers combine with essential trace elements, like iron, causing nutrient deficiencies. PROPER pH 6.5, 7.0, and 7.5 should not be used in aquariums where algal growth is desirable.

Will API PROPER PH increase carbonate hardness?

Carbonate hardness, also known as “alkalinity” and “KH,” is the level of bicarbonate and carbonate ions in water. The KH level is also a measurement of water’s ability to resist pH change. API PROPER PH 8.2 contains bicarbonate and carbonate buffers, and will directly increase carbonate hardness. API PROPER PH 6.5, 7.0, and 7.5 contain no carbonate hardness, but will cause a spike in KH as measured with KH test kits. These kits work by acidifying the water in the test tube, drop by drop, with a test reagent. When the water sample is adequately acidified, a color change occurs in the test tube. This is called the “end point.” The number of drops of test reagent required to acidify the sample (causing a color change) indicates the level of KH. Phosphate buffers strongly resist pH change, and will be measured just like bicarbonate and carbonate buffers. Therefore, API PROPER PH (6.5, 7.0, and 7.5) will cause an increase in KH measurements.

Will phosphate buffers affect carbon dioxide test kits?

Yes. Carbon dioxide test kits work much like carbonate hardness test kits. A water sample heavily buffered with phosphate buffers will resist the pH change required to reach the end point color change. This in turn causes a “false high” carbon dioxide level test result. You will not be able to accurately measure carbon dioxide levels when phosphate buffers are added to your aquarium water.

    Great for Balancing the pH levels

    By on

    This works great to help balance the pH levels in all of our fish tanks. We have a regular betta tank in our living room and a couple of fish tanks set up for an aquaponic ecosystem, so we are always having to maintain a good pH level. This is by far one of the best balancers we have found.

    I have used this product since I was a kid and it REALLY works!!! Have raised fresh water, 200 gallon living salt water reefs and owned my own Koi and pond set up as well. This stuff is still the best after all these years!!
