Our 10 Best Digital Ph Testers for Aquarium of 2022

A pH meter should be on top of your list of priorities, whether you have a lavish saltwater aquarium or a small freshwater goldfish tank. It will ensure that your fish and plants in your tank grow in the best possible environment, and it will prevent them from getting sick.

Choosing the perfect pH meter and using it to monitor your aquarium’s health may be difficult at first, but we’re here to guide you through the process.

How to Choose the Right pH Meter

Choosing the right pH meter will ensure that your aquarium and all its inhabitants thrive. Although accuracy is the most important factor in picking a pH meter, there are many other aspects you should consider as well.

Types of pH Meters

If you’re looking for a pH meter, you have many options. You’ll want to know which type of pH meter you’re looking for before you even begin looking at your choices. There are two kinds of pH meters: manual and digital. Both have their advantages and disadvantages, which we’ll explore in more detail here.

Manual pH Meters

The manual pH meter is an inexpensive and easy-to-use option for those just getting started. As they typically come in a small kit that you don’t have to clean, you simply place the strips in water and wait until they change color to indicate the water’s pH.

A manual pH meter isn’t as accurate as a digital pH meter, and it takes a bit longer for it to get a pH reading. You have to replace old strips with new ones, even though they come with multiple strips, so you won’t run out. This is the more economical option if you don’t plan on testing pH often.

Digital pH Meters

A digital pH meter is the way to go if you are always concerned with the pH level of your aquarium or water. Based on the option that you purchase, they may also be more accurate than manual kits and pH test strips, as some can go to several decimal places. They can also be reused over a long period of time since they get a reading much faster.

You’re making an investment to keep your aquarium healthy by purchasing these, but they’re also more expensive than traditional pH test strips. Aside from cleaning and calibrating the meter often, you will also need to ensure that it works as it should and does not break down.

Features to Consider When Buying pH Meters

It is important to consider and balance a variety of factors when choosing a pH meter. Depending on the delicate balance of your aquarium or refugium, you may not have to buy the most expensive meter.

Accuracy

A pH meter’s accuracy is one of its most important considerations. Meters with lower accuracy, like manual ones, are less expensive. You can opt for a cheaper meter that may not be as accurate if you are only concerned with where the pH is rather than the exact pH reading in your aquarium.

You’ll want to make sure that your pH meter can give precise, accurate readings consistently if your aquarium or refugium requires an extremely specific pH. The most accurate pH meter that we have is the Apera AI316 Series.

Ease of Use

The calibration settings for some pH meters will need to be adjusted when you take them out of the box because they are more advanced. There are also devices that can be used right away, with special calibration buttons and detailed instructions. pH meters that are easier to use are preferred, but you might want something with more customization options if you want something truly tailored to your aquarium.

Power and Portability

It is not ideal for when you need to measure pH on the go because some pH meters are heavy or large and drain batteries quickly. Others even require you to plug them in to work. The Apera AI209 Series is ideal if you plan on traveling because of the power required and portability of the meters.

Display

Make sure that your pH meter is easy to read and decipher, whether it’s through sharp contrasts of color on the pH strip or a clear digital display when it’s used. The Bluelab combo meter has a large display that is easy to read, so it’s perfect for testing pH in dimly lit environments. It has a backlight on the display.

pH Range

You won’t be able to read all pH ranges with all meters. While this is usually okay, you’ll want to make sure your aquarium situation doesn’t require a reading outside of the usual range in your meters. A pH meter’s range usually runs from 0 to 14, but a few can run from -2 to 16. Manual meters may have lower ranges.

You can use any pH meter on this list for the 6-8 range that almost all common aquarium fish use, but if you have a species that is less common, read our guide below for more information on the proper pH.

Here are our top picks for reliable and affordable pH meters if you want to make sure you choose the right meter without draining your wallet.

The strips are affordable, work on freshwater and saltwater aquariums, and you only have to dip them in the water for less than a minute to gather a reading.

Due to the fact that this is a manual pH meter, it won’t be as accurate as the other meters. According to the colors, this meter can measure pH only up to 9.0, so if the pH of your aquarium water is higher or lower, you should buy a different meter.

Additionally, it will only show colors between 6.0 and 9.0 for pH, and it will also be less precise for the other water measurements. If you need more precise measurements, please use the Tetry EasyStrips collection.

Despite the fact that each reading will not be exactly correct, this strip will provide you with a comprehensive overview of the pH level in your aquarium tank. As the average pH fluctuates from day to day regardless, you might not need a testing kit with excessive accuracy. If you want to just test the waters once or twice irregularly, this meter is the one for you.

Pros

  • Measures five different categories of water quality
  • Needs less than a minute to gather reading
  • A comprehensive overview of water status
  • Affordable
  • Works for saltwater and freshwater

Guide to Picking the Perfect pH Meter

From how pH meters are designed to their accuracy, to their functionality, each pH meter is unique. Read more to determine whether a manual pH kit or a digital pH kit is best for you. We have a full guide to help you pick out the perfect pH meter for your aquarium.

What pH Should My Aquarium Be?

Freshwater aquariums should have a pH between 6.8 and 7.6 for the vast majority of plants and animals. Some fish, such as some tetras, prefer a pH below this range, while others, like cichlids, prefer a pH above this range, but anything within this range shouldn’t be problematic.

The pH level of saltwater fish tends to range between 8.0 and 8.4. Although there are some exceptions, most fish can tolerate anything within that range.

It is possible that some fish won’t be happy in a tank that falls within one of these two ranges-so be sure to check with your fish before using this method.

You can raise or lower your pH by picking up a pH meter and following our guide.

Why Do I Need a pH Meter?

When you know your tank’s pH value, you can figure out whether or not it’s acidic or basic. Values above 7.0 indicate alkaline, whereas values below 7.0 indicate acidic. If the pH of your tank is exactly 7.0, it’s considered neutral.

The pH level of your aquarium can affect the health of your fish and plants.

Adding new fish and plants may also cause the pH levels in your tank to constantly change. The pH balance usually drops at night due to fewer plant respirations and photosynthesis, while it rises during the day. If the water changes, you will need to test it frequently to ensure it stays in a safe range.

Dangers of Low pH

A pH below 6.0 will end up killing the natural nitrifying bacteria in the tank, leaving the water with a high concentration of ammonia ions and nitrites, which are toxic to fish.

The concentration of ammonia ions and nitrate in your fish will slowly increase if left unattended, until you lose your fish. As a result of low pH, your fish may also produce extra mucous, leading to eye damage, hyperplasia (thinner skin and gills), and breathing difficulties.

Dangers of High pH

A pH of too high will result in a reduction in ammonium ions, but an increase in actual ammonia concentrations. Despite the fact that ammonium ions are less harmful to fish than ammonia, both are harmful to fish and plants in the aquarium. When left unchecked, water with a high pH level can damage your fish’s gills and eventually kill them.

To ensure that all of your fish thrive in your tank, keep the pH mostly balanced between the recommended levels.

Features to Look for in pH Meters

The pH of your fish is determined by its species and where it came from. There is no one “normal” pH for all fish. In contrast to saltwater fish, tropical fish from Brazil prefer pH levels from 5.5 to even lower, while saltwater fish prefer a pH of at least 8.0. Make sure that fish you are planning to buy fall within the pH range of your water and within the range that your meter can measure before you purchase them for your tank.

A pH meter can be used not only for aquarium tanks, but it is designed for a variety of purposes. While some pH meters made for testing soil can be used in your aquarium, you should ensure that any meter you buy is waterproof. In addition to investing in a pH meter designed for aquariums, gardening pH meters can also be used, as long as they are resistant to water.

Automatic Temperature Calibration

It’s important to look for a pH meter with ATC, or automatic temperature calibration, as the pH level of the tank can change depending on the heat level. Therefore, meter with built-in temperature calibration and sensor can save you the time of doing the math yourself to determine what the pH level really is.

Waterproofing

There are some pH meters that are not completely waterproof like the Bluelab pH pen. They will have waterproof probes but won’t be able to be submerged at all.

Science Behind pH Meters

There are two ways to measure pH, a manual kit and a digital meter. Here we’ll explain the differences and how both work to ensure you understand exactly how each measures pH.

Manual pH Meters

When a pH meter is in contact with hydroxide or hydrogen atoms, a chemical indicator changes color. Flavin is often used to change the color. If you order the meter, you will receive a color key which you’ll need to match to the meter’s color.

You may find these meters less accurate when attempting to visually match hues to the paper as colors come in continuous ranges.

Digital pH Meters

To use digital meters, first you need to understand how water composition varies according to its acidity. The more acidic water is, the more hydrogen ions it has dissociate from its molecules. As a result, these ions are separate charges that float around the water and have a greater potential to produce an electric current.

In basic solutions, however, there are usually several hydroxide molecules, which prevent electric currents from flowing. A pH meter measures how easy it is for water to conduct a small amount of electricity, and returns the result as a pH value.

Calibration is also required so that it has a reference point for measuring so that you get accurate readings.

Steps to Using a pH Meter

For an accurate reading, it’s important to follow all the instructions on the pH meter. With a manual meter, you just need to make sure you leave the paper strip in water for enough time. Your kit will tell you how long to wait, but you’ll be able to compare it with the color-coded key included with your purchase and choose the hue closest to the paper strip after the recommended amount of time has passed.

You’ll want to calibrate your digital meter first if this is your first time. If this is your first time, that’s something you’ll need to do. In the first instance, you’ll want to clean your meter with deionized water after you’ve taken a small sample of water from your tank. As soon as it has dried, place it in the solution and let it stay for several minutes to stabilize. Dry it off and store it safely after reading it.

Calibrating a Digital pH Meter

You can calibrate your digital pH meter most reliably by using buffering solutions. You can buy buffering solutions online, which have a known pH. Even if you don’t have a buffering solution, you can still calibrate the meter with the help of a few basic ingredients.

The pH meter you bought will also determine how often you need to calibrate it.

You should calibrate higher accuracy meters before each use; lower accuracy meters should be calibrated every week or biweekly. In addition, you should calibrate it after you test it in strongly basic or acidic solutions.

Calibration With Buffering Solutions

It is possible to program your meter to read the pH of a buffering solution if you have one. You will first need to put your meter in a neutral solution with a pH of 7 and leave it there for a few minutes. After you’re certain the readings have stabilized, you can adjust your meter to display 7.

Once you’ve done that, you’ll want to repeat the process for all other buffering agents.

For the best results, you will need at least one basic solution and one acidic solution. To keep your pH meter clean, wipe it off with water and then dry it off. In order to get an accurate reading, you need to make sure that the buffer stays in each solution for a long time, and you need to be familiar with the pH of all of your buffering solutions.

Making Your Own Buffering Solution

It is easy to make your own buffering solution if you don’t have available options! If your local store sells buffer tablets, you can purchase them and add them to the recommended amount of water. You may have to purchase some MKP (monopotassium phosphate) and KOH (potassium hydroxide) if you can’t find any tablets.

A downside is that you will have to use a pH test strip or borrow a pH meter that has already been calibrated so you know how much you need to add. You should add about 10 grams of MKP to a container of water after filling it about three-fourths up. To create your neutral buffering solution, use your pH test strip or meter and slowly add KOH flakes until you reach a pH of around 7.

To make a more acidic buffer, add 20 grams of citric acid at the start instead of MKP, then start adding KOH until you’re at the desired pH level. In order to make a basic buffer solution, you will need an ammonium chloride or ammonia solution. You just have to add ingredients slowly while using the pH strip or meter until you reach the desired pH level. Once you are done, you will be able to calibrate your new digital pH meter.

Manual or Digital Meters?

Manual meters are better suited to beginners who only need to check frequently. They don’t have calibration issues like digital meters, and they don’t need to be cared for or cleaned after each use.

If you are testing frequently, though, the affordable price will add up if you have to purchase multiple boxes.

In addition to creating buffer solutions and managing calibration (though some meters are easier to calibrate than others), digital meters require more involvement from you. Manual kits cannot always adjust for temperature. The initial purchase involves a higher cost, but it will pay off if you plan to test pH frequently over a long period of time. You’ll also get better readings because of the higher accuracy.

The last thing to remember is knowing how much information you want from your tank. A lot of manual pH kits also test for things like nitrite and nitrate concentrations, as well as free chlorine ions and water hardness. It is common for digital meters to only provide you with pH readings, but remember that fish can survive and thrive in a wider range of pH levels than they can with digital meters.

How to Change My Aquarium’s pH Level

In the event that your pH level differs significantly from the recommended levels in your tank, you should fix it before any of your fish get sick. You don’t want to change the pH levels too drastically – the most important thing for your aquarium is a stable pH environment.

As long as you don’t get the pH level exactly on the middle of the recommended level for your fish, you should adjust it slowly over time. Even a change of 0.3 can be deadly for your fish.

The pH level of your tank can be changed in a couple of ways, as long as it falls within your pet’s acceptable range. With that being said, here are some ways you can change the pH level.

Raising pH Level

The pH level of the aquarium can be raised easily by changing the water regularly. Getting rid of extra food and waste can also help raise pH levels (or at the very least counter the dropping pH levels) if you have a larger aquarium and need to change the water a little bit at a time.

It is also possible to increase the pH in the water by adding crushed coral or limestone, though it does not take much to raise it. You will, however, want to add it very slowly to avoid exceeding the recommended level.

If you use baking soda, you’ll need to add it constantly over time. A teaspoon of baking soda is usually enough for five gallons of water.

Lowering pH Level

The process of lowering pH in your tank is much harder than raising it. Nevertheless, you can lower pH over time by filtering the water with peat moss. You can also add driftwood to decrease pH, or pump in more carbon dioxide at a reasonable rate to decrease pH. In spite of the fact that some chemicals exist to lower pH, these are temporary solutions rather than permanent ones.

Digital pH Meter Care Tips

A good digital pH meter can be very expensive, so you should take good care of it. If you’re careful, you’ll be able to use it for a lifetime, which justifies the higher upfront cost. The Apera AI209 Series comes with brushes and care kits. In order to ensure that your meter keeps working for a long time, here are some tips to get the most out of it.

Keep It Calibrated

It is important to calibrate a pH meter regularly to ensure it gives accurate readings. If you don’t calibrate a pH meter, you may get inaccurate readings, which is detrimental to the health of your tank. Furthermore, keep it in a dry, safe place and make sure the tip is covered with a cap that comes with it. Don’t let the meter get wet when it isn’t in use.

Keep It Clean

When you use the meter, you must wash it off and remove any solution from it every time. The oil on your finger can damage the meter and mess up future readings if you touch the sensor electrodes or reference cell at the tip. Make sure you read all instructions thoroughly before using the meter.

Keep It Protected

In general, pH meters should last for years if you take care of them. Keeping them away from extremes in temperature and humidity and keeping them dry goes a long way when it comes to maintaining their quality. To get rid of air bubbles, swirl the meter in solution before and after you use it.

Final Words

You can maintain a healthy aquarium by using the right pH meter, which ensures that your fish and plants are thriving on a daily basis. Check your tank’s pH levels carefully, and make sure they don’t deviate too much from the recommended value. You will soon be able to enjoy a perfect environment for all the living creatures inside your tank if you take care of it and use pH meters and kits properly.
