14 best ph indicators

pH indicators are substances used to determine the pH (acidity or alkalinity) of a solution. In the context of aquariums and fishkeeping, pH indicators are commonly used to monitor and maintain the water quality, as the pH level of the water can have a significant impact on the health of fish and other aquatic organisms. Here's what you need to know about pH indicators in aquariums:

  1. Purpose: pH indicators are used to measure the pH level of the aquarium water.The pH scale ranges from 0 to 14, with 7 being neutral, values below 7 indicating acidity, and values above 7 indicating alkalinity. Most freshwater aquarium fish thrive in water with a pH between 6.5 and 7.5, but the ideal pH can vary depending on the specific fish species.

  2. Types of pH Indicators: There are different types of pH indicators available for aquarium use. Some common ones include:

    • Liquid pH Test Kits: These kits typically include a liquid reagent and a color chart. You add a few drops of the reagent to a water sample, and the color change corresponds to the pH level.

    • pH Test Strips: These are paper strips impregnated with a pH-sensitive dye. You dip the strip into the aquarium water and compare the color change to a provided chart.

    • Digital pH Meters: These are electronic devices that provide a numerical reading of the pH level. They offer precision and are often used by serious hobbyists and professionals.

  3. Monitoring pH: Regularly testing and monitoring the pH of your aquarium water is essential. Changes in pH can stress fish and affect their health. Factors like the type of substrate, the presence of driftwood, and the biological processes in the aquarium can influence pH levels.

  4. pH Adjustment: If the pH level in your aquarium is not within the preferred range for your fish species, you may need to adjust it. This can be done by adding pH-adjusting chemicals or using specific substrates like crushed coral or limestone that naturally increase pH.

  5. Caution: It's important to note that sudden and drastic changes in pH can be harmful to fish. Any adjustments should be gradual to avoid shocking the aquatic environment.

In summary, pH indicators are valuable tools for aquarium enthusiasts to monitor and maintain water quality, ensuring a suitable environment for their fish and aquatic pets. Regular testing and appropriate pH adjustments, if necessary, can contribute to the overall health and well-being of the aquatic inhabitants in your aquarium.

User questions & answers

Question: How Do you use these correctly? It's not working for me
Answer: Use glass stick or cotton swab to dip a small amount of the substance to be tested on the Yellow test page, and compare the colorimetric card to see the corresponding pH value of the color. If the test strip does not change color or is always a color, it may be because the acidity and alkalinity of the tested liquid is 6, which is yellow just like the color of the test strip, or the pH values of the tested liquids are almost the same.
Question: can I use these to test cosmetic products, such as moisturizers, serums, face masks, ect
Answer: Yes, if itcosmetic product is liquid or milky, drip directly on the test paper and wait until the color changes, to compare the color card to see which PH value it belongs to.The pH of the skin is about 6, which is weakly acidic, so the most suitable cosmetics are also in this range
Question: will these work on alcoholic beverages
Answer: The pH strips test for the degree of acidity or alkalinity of a solution and I suppose it should work on an alcoholic beverage depending upon what the beverage consists of besides ethanol. I initially bought the paper to test the acidity of cheeses I make, but have also used them for wine making to evaluate for acid content.
Question: I intend to use this as a visual indicator to help a child who has difficulty differentiating between wet and dry pull ups. Will this work
Answer: Just a tip: dry pullup is always flat, wet pullup is bulky and puffy. The puffiness is a tell tell sign better then any devices.

Question: Is therer a color chart to indicate ph level? Is this good to measure drinking water from a well
Answer: If I remember correctly it's vacuum sealed until you used it with a bit of solution. We were a bit nervous expecting it, but it's not bad. Even after she dissected it, it stayed on her desk in pieces (insides thrown away obviously) for a day or two before she finally threw it away. It was definitely presses erred so well there was no odor at all. Good Luck, having never done it in school it was easier than I thought it would be. My daughter was in either 4th or 5th grade and loved it!!!

User questions & answers

Question: Is this non toxic
Answer: Please do not consume this product. This products sole purpose is to test the pH of any clear water. Please keep away from children, unless they are under adult supervision.

Question: How long will the color remain in the water? Will it fade away right away? It's for a science fair
Answer: It does not fade right away, but I’ve not timed it long enough since I throw the solution out as soon as it changes to the color that it should be.
Question: Does it do the whole scale
Answer: Our pH Test Liquid identifies the pH of water samples with a range of 4-10 on the scale.

User questions & answers

Question: Can you test you urine for high body ph with these strips
Answer: i would not advise 3 drops for 8 oz to be accurate. the container that came with my original test kit only holds about 1/2 tablespoon of water. so if you want/ or need to test 8 ounces you would have to calculate how many 1/2 tablespoons are in 8 oz. approximately 32, times that by 3, you get 96 drops. so it would be easier and more economical to test 1/2 teaspoon of water. hope that helped
Question: If something had a pH of 4.5, would the strip look somewhere between the 4&5 colors? And are those colors different enough to make that determination
Answer: NO, this is not iodine. This is just a special kind of dye that changes color depending on the acidity of a solution.
Question: Accurate for use with aquariums (3.5 gallon tank
Answer: This is a solution.
Question: can these be used to test the ph of facial cleansers
Answer: I purchased my 8 oz. bottle about 4 years ago, still works great. I transferred some into a smaller bottle to use, then refilled it when emptied.

User questions & answers

Question: I want to test shampoos, conditioners, and hair oils. Will this read accurately by just dipping into product
Answer: 04/17
Question: Want to test rain water used for house plants, is this the right strip to use
Answer: Hi 5drops per 44ml
Question: Is there any reason why I couldn't use these to test the pH in cheese I'm making
Answer: This reagent is for use with a Taylor test kit, such as the K-2006 FAS-DPD chlorine test kit. If you have one of those, or at least the pH comparator tube (the one with the colored windows to compare the color of the test water to), then yes, you can then use this reagent to find the pH of drinking water (if it's between 7.0-8.0). If the test water is out of this range, then no.When used with the Taylor K-2006, you can measure the pH in 0.2 increments (from pH 7.0-8.0).
Question: Can they be used to test the PH of bodily fluids such as the PH in the vagina
Answer: Thank you for your question. This item's descriptive data is currently all messed up. I reported it to Amazon several days ago and it remains a disaster. This item is supposed to be a Taylor R-0004 reagent in the 2 oz size (a.k.a. R-0004-C). There is no "2.75 oz" size available and this is NOT a DPD reagent. it is a pH Reagent.

Product features

Macherey- Nagel, 92110, 0-14 pH Indicator Strips 100/box

Safe analysis by long plastic handle

The long plastic handle safely protects you from coming into contact with the sample. Thus, testing toxic, dangerous or aggressive substances is safely possible.

No bleeding due to color bounded indicator dyes

In contrast to common indicator papers, the indicator dyes in pH-Fix test strips are chemically bound to the test pads. This patented technology safely prevents bleeding of dyes into the sample, even in highly alkaline solutions. Your sample is not contaminated by indicator dyes. Consequently, you can use the solution for further analysis.

The special non-bleeding technology provides additional benefits for you:

Even in weakly buffered solutions, a safe and reliable pH determination becomes possible, as the strips can be immersed for a long time until the final reaction color has developed.

The colors of the individual test pads don’t bleed and mix, which assures exact comparison to the color scale.

Your sample is not contaminated by indicator dyes.

Question: We currently use Phenolphthalein indicator containing 42 % Isopropanol. Will this work the same
Answer: I use the TF-100 kit so I'm not sure. I would google your question.
Question: Does this item expire
Answer: I use this with the test kit where your add 5 drops and compare the color on the chart to determine the PH.
Question: I’m looking for old laxatives with this
Answer: Sort of. You only add two drops instead of 5. ( or vice versus)😀
Question: Can this be disposed of in a normal sink
Answer: Hello Marion, If you purchased your pH testing solution separately, they wouldn't have given you a chart. If you purchased the kit, you would have been supplied with a dual plastic measuring device that shows you how much water to add to the right side chamber prior to putting in the 5 drops of Taylor R0014A to test your pH level. The other side is for testing for chlorine or bromine. In the center of this device is the color guide with a number in the center of each color. Regarding measuring well water pH from the well, I suspect it would be accurate. However, you may want to check with your pool supply manager (some people with wells do have swimming pools) or the company that supplies the filter for the well water to your home. I'm not sure if the minerals in well water would affect the testing solution. You could also contact the Taylor company directly.

Since soil most often is in/close to neutral state (with pH value of 7), it is highly likely that you find the needle in display window stay still (because the default pH value is set at somewhere between 7 and 8) when you use it to test the pH value of soil. Customers sometimes are misled by this appearance and hence regard the tester as a defective unit by mistake.

How to Use:

Step 1: Switch to moisture/pH/light position according to demand.

Step 2: Insert the probe into the soil about 2-4 inches.

Step 3: Check moisture/pH/light level in the dial after 10 minutes.

Step 4: Remove probe from soil and wipe clean after each use.

Kindly Note:

1. Do not force it into very hard soil or touch hard objects since it will be easy to damage the probe.

2. Do not use it to test pure water or other liquids. It can only be used to measure soil.

3. Do not leave the meter in the soil for a long time.

4. Please wipe and clean the probe after each use.

5. If the soil is too dry the indicator will not move, and water it before testing.
