How to Measure pH Level in an Aquarium?
How to measure pH level in an aquarium? The best way to measure the pH level in an aquarium is with an electronic pH meter.
1. Liquid Test Kit
Liquid test kits measure the pH of the water by mixing it with a color-changing chemical (phenol red).
The water is then compared to a chart of colors and the pH result is determined. Because this method depends on human interpretation of colors, it can be difficult to get accurate readings.
These tests can also give inaccurate readings if the water is not mixed well, so it is important to shake the bottle before use.
2. Electronic pH Meter
Electronic pH meters measure the pH of the water by passing a small current through it and measuring how much voltage this causes.
Because they do not rely on human interpretation, electronic meters provide accurate measurements.
However, they require calibration to be performed at the beginning of each day and proper storage in order to maintain accuracy.
Electronic meters require the addition of electrodes to the water that slowly become depleted over time and should be replaced periodically.
It is also important that users follow instructions for the proper use and storage of electronic meters because improper handling can cause damage to the equipment and inaccurate readings.
3. Ammonia Alert
Ammonia alerts provide an easy-to-read, color-changing display that provides a warning if dangerous levels of ammonia are present.
This product does not measure pH level in an aquarium itself but can help you avoid unsafe conditions by acting as a warning system for high ammonia levels.
4. Other Meter Options
There are various other types of meters that work in different ways.
Some can test pH, nitrite, and/or ammonium at the same time.
These units are typically more expensive, but they provide a fast and simple way to get accurate readings from your aquarium without needing multiple tests or equipment.
Which type of meter you use is a matter of personal preference and budget.
As long as the user follows the manufacturer’s directions for proper calibration and maintenance, any type of pH meter can provide accurate readings.
What pH Level Should the Aquarium Be?
Now that you know how to measure pH level in an aquarium, what pH level should the aquarium be?
The pH level in an aquarium depends on a variety of factors including fish species, age of substrate, live plants, water source, etc.
This is why it is difficult to recommend a specific tool to measure pH level in an aquarium.
However, keeping the water in your tank between 6.5 and 8 usually results in good conditions for most species of fish.
pH is an important factor when determining what type of fish you want to put into your aquarium because certain species do better in specific conditions.
Fish bred by humans are less likely to have special care requirements but some species, like Discus fish, require very particular water parameters in order to thrive.
Fish breeders will often adjust the pH level of the aquarium before introducing new stock to ensure that it is compatible with existing fish or more likely to spawn successfully if breeding.
Discus fish requires a pH level of 6.5-7.5, although breeders have been successful in lowering the pH to 5.0 with live plants and acidic substrates.
Goldfish can survive in a wide range of pH levels but most species prefer water that is more alkaline with a faster-moving current.
For example, the recommended pH level for celestial pearl danios is 6.5-7.5 while Bettas should be kept at a slightly higher pH of 7.0-8.0
The ideal pH for koi can range from 7 to 8 depending on the type of fish and whether or not they are used to living in ponds with algae blooms.
What Causes Low pH Level in an Aquarium?
A low pH level is one of the most common reasons why aquariums have problems. Yet, it is also one which is often overlooked or misunderstood.
What causes a low pH in an aquarium and how can you correct it?
The pH scale goes from 0 up to 14. A pH of 7 is considered neutral, water with a pH below 7 is considered acidic, while water with a pH above 7 is defined as being alkaline.
Most saltwater fish are very sensitive to changes in the pH of their environment. A slight change in pH can cause stress or even death in most fish species.
As such, it is important to keep the pH level of your aquarium within the desired range.
In a closed system such as an aquarium, pH is influenced by a variety of factors. Some factors are difficult to control and others can be easily controlled with regular water changes and other techniques.
1. CO2 Production in the Aquarium
When fish or invertebrates respire, they produce carbon dioxide (CO2) as a waste product. This CO2 dissolves in the water and lowers its pH.
When extra CO2 is added to an aquarium, such as when fish are overfed or new live rock is added, the pH can drop very quickly.
The amount of CO2 dissolved in water is dependent on the water’s temperature, salinity (specific gravity), and the amount of CO2 in the air.
The warmer, saltier, or more humid the air, the more CO2 will dissolve into it.
How to reduce low pH level caused by high CO2 levels? Maintain good oxygenation of your aquarium by ensuring adequate water flow and aeration.
Keep the lid off your aquarium to allow more CO2 to escape, as well as provide extra ventilation for your fish. Regular water changes will also reduce the build-up of CO2.
2. Fish Respiration
A side effect of their gills’ function is that fish release carbon dioxide (CO2) as a waste product.
A fish-only aquarium with too many fish or the wrong type of fish will have an increase in CO2 levels and therefore pH.
In addition to this, some species of fish require a very low pH level to survive. Cory cats, for example, need a pH level below 7.0 to thrive.
How to reduce low pH level caused by high CO2 levels? Keep an eye on your stocking levels and, if need be, add more fast-swimming, surface-dwelling species.
To raise the pH in a low-pH species tank, use reverse osmosis (RO) water rather than tap water to top it up.
This will reduce the amount of CO2 released into the water.
3. Nitrogen Cycle
The nitrogen cycle is the process in which toxic ammonia (NH3) is converted to nitrite (NO2-) and then nitrate (NO3-) by beneficial bacteria.
A low pH suppresses this bacteria’s activity, slowing down or even stopping this vital natural process.
How to reduce low pH level caused by the nitrogen cycle? There are several ways to solve this problem.
One solution is to maintain a buffer in the aquarium water, for example, by performing weekly water changes, which also maintain your nitrate levels.
Another way is to use RO water (see point 2) on a regular basis as well as using reverse osmosis water conditioner (such as the one made by Seachem).
This removes not only excess nitrate but also carbonate hardness (KH), which is essential for maintaining a stable pH and inhibiting the nitrogen cycle.
4. Other Chemicals
If you use tap water to top up your aquarium, it can contribute to lower pH.
Tap water contains dissolved chemicals such as chlorine or chloramine, which interfere with the nitrogen cycle and can cause changes in pH.
If you plan to use tap water, it is vital that you remove the chlorine/chloramine by using a de-chlorinator.
What Causes High pH Level in an Aquarium?
1. Water Changes
If you use tap water to top up your aquarium, the dissolved chemicals it contains can raise the pH level.
Tap water often contains chlorine or chloramine, which raises pH and inhibits nitrifying bacteria.
If you plan to use tap water to top up your aquarium, it is vital that you remove the chlorine/chloramine by using a de-chlorinator before adding it to the tank.
2. Live Rock
When live rock is cured (see point 4), it converts into aragonite, which raises pH.
However, if live rocks are not cured before being added to an aquarium, it can reduce pH instead.
3. Freshwater Driftwood
Driftwood absorbs CO2 from the water, giving it an acidifying effect on the tank’s pH.
However, over time, this driftwood releases tannins into the water, causing a reduction in pH. This process takes several weeks and can even take up to a year or more for some types of driftwood.
How to reduce high pH level caused by driftwood? Place the driftwood in an aquarium outside of the tank and use a de-chlorinator on it before adding it to your main tank.
4. Crushed Coral
Adding crushed coral (coralline algae) to an aquarium raises its pH level. However, if you have a pH that is too high, you can use crushed coral to lower it.
5. Alkaline Additives
Adding certain types of alkaline additives can raise your aquarium’s pH level. Examples include “pH up” and “pH minus.”
6. Reverse Osmosis (RO) Water or Distilled Water
Both RO water and distilled water are very pure water that does not contain any dissolved chemicals.
The lack of these chemicals means that your pH is more likely to stay at its natural level.
7. Live Plants
Plants use CO2 during photosynthesis, which can cause a rise in pH over time.
How to reduce high pH level caused by live plants? In a plant-free aquarium, the pH is usually around 7.8 to 8.2.
However, if you keep live plants in your tank, it will gradually rise to 9 or higher.
8. Reverse Osmosis (RO) Water or Distilled Water + Live Plants
Because RO water and distilled water do not contain any dissolved chemicals, plants will not use these chemicals during photosynthesis and the pH can remain stable.
9. Calcium
The concentration of calcium (Ca) in water is what determines its alkalinity.
If you go on a low-calcium diet, your body’s pH becomes more acidic. This is because, without sufficient calcium, the body loses its ability to maintain alkalinity.
10. Carbon Dioxide
As mentioned above, plants use CO2 during photosynthesis, which can cause a rise in pH over time.
If you reduce the amount of CO2 in your tank by using an air stone or adding live plants, this can lower the pH level.
11. Fish Waste
The nitrogen cycle converts organic waste into ammonia, which can then be converted into nitrites and then nitrates.
However, if the pH level is too high, this conversion slows down or stops almost completely.
12. Alkaline Additives + Live Plants
Using certain types of alkaline additives (see point 7) increases the alkalinity (BIC) in your aquarium.
This can cause an acidifying effect, which reduces the pH level in an aquarium.
13. Baking Soda
When baking soda is added to tap water, it raises its pH level.
However, when baking soda reacts with vinegar (CH3COOH), this causes a chemical reaction that reduces the pH level.
14. Uneaten Food
Uneaten foods can cause a rise in pH. This is because these foods slowly turn into ammonia and nitrite in the aquarium, which can then cause a rise in nitrate.
Conclusion
How to measure pH level in an aquarium?
pH levels should be kept between 7.0 and 8.4 for optimum water conditions in an aquarium.
Check your pH level with a test kit, or use one of the calculators available online to get a general idea of how it’s doing before you add any fish!
