As you can see, these test strips are very comprehensive and diverse, and should be able to provide you with information about virtually every water parameter.

These are also very reliable strips, and they are made out of high quality paper that should not bleed. All you have to do is dip the strip in the water for a couple of seconds and then wait for about half a minute for the results to show.

You can then take the strips and compare them to the color chart on the bottle. It really doesn’t get much easier than that. What I personally really like is that this product comes complete with its own ebook that tells you exactly what each of the results means and what you can do to improve those results.

This aquarium test kit comes complete with everything you need to measure all of the water parameters. Just like all the other products we have looked at so far, this takes the form of a simple testing strip that provides you with information about the water parameters.

This is a 7 in one water testing kit that is able to test for total hardness, nitrate, nitrate, chlorine, total alkalinity, carbonate, and pH.

These are the seven most important parameters for aquariums, and this product can test for them all. These test strips are made out of premium fiber paper and are made with very sensitive materials. This means that the results are very clear and easy to read, there is no color bleeding, and the strips themselves are also very accurate.

 You simply have to dip the strips in water for two seconds and then hold them horizontally for 60 seconds after removing them from the water. You can then compare the results on the strip to the color-coded chart contained on the outside of the bottle. It really doesn’t get much easier than that.


  • Fast and easy
  • Affordable
  • High-quality paper
  • Accurate
  • 7 in 1


  • More expensive than some others

All of these test strips may not be the cheapest in the world, they are very accurate, which is always worth a lot.

  • 💧 THE CARETAKER OF YOUR TANK – Aqualuna’s 6-in-1 kit provides quick and reliable results to...
  • 💧 TEST FOR 6 PARAMETERS - Monitor pH levels, general water hardness, nitrate, nitrite, carbonate...

If you are looking for something more affordable, and have limited testing needs, then this is a fantastic product to check out. What you get here is a six in one testing kit that is able to test for pH levels, general water hardness, nitrates and nitrites, chlorine, and carbonate.

It’s not the most comprehensive testing kit around, especially when compared to some of the others on this list today, but it is very affordable. Even more important than affordability is accuracy, and these aquarium test strips are most certainly quite accurate. This is due to the way in which they are made, mainly thanks to the high-quality paper that they are made out of.

There is no color bleeding, and the results are very easy to read. Even better is that the color-coded chart on the bottle is also very easy to understand, so you’ll always know exactly what to do when you get your results. Something that also stands out about this product is that it is ideal for both freshwater and saltwater tanks. Just get them in the water for a couple of seconds, wait a minute, and you’ll have your results.


  • No bleeding
  • Good paper
  • Great price
  • Fast and easy to use


  • Only tests for 6 parameters

If you just need some simple test strips that can test for the six main water parameters that are important for aquariums, then this is a product I would recommend.

  • Contains one (1) API 5-IN-1 TEST STRIPS Freshwater and Saltwater Aquarium Test Strips 25-Count Box
  • Monitors levels of pH, nitrite, nitrate carbonate and general water hardness in freshwater and...

Here we have some aquarium testing strips that come to us from a very popular and trusted brand name, which is why I have included them here. Interesting to note is that here you can get a 25 count, 100 count, or a much smaller 4 count option.

Something you do need to know however is that for just 25 of these strips, you pay just as much as you do for 100 strips of any of the other products. It is therefore comparably expensive.

That said, I do also think that this might just be the most accurate product on the list today. It is made with very high-quality paper, so there should be no color bleeding, and it’s also designed to be very easy to read. You then just compare the results to the chart included in the instructions and should know exactly what your water parameters are like.

Simply dip the test strips in the water for a couple of seconds, wait for a minute, and you’ll have your results. This is a product that can be used on both freshwater and saltwater tanks and it is a five-in-one test kit that is able to test for nitrate, nitrite, pH, general water hardness, and carbonate.


  • Well known brand
  • Fast and easy
  • Super reliable
  • Tests for the 5 most important parameters


  • Quite expensive

If you need something very reliable and you don’t mind paying a bit of extra money for it, then this is the number one product I’d recommend.

Aquarium Test Kits Buyers Guide: What To Look Out For

Before I call it a day, let me provide you with some important tips on choosing the best aquarium test kits.


There are two main types of aquarium testing kits out there, and the ones I’ve chosen to review today are all manual ones that involve paper strips.

Hand holding aquarium test strip pads to check aquarium parameters

These are generally best for home use as they are very simple to use, don’t require calibration, and don’t require any extensive knowledge. There are also more advanced options such as digital water testing tools, although these usually require a good deal of knowledge and maintenance.

Accuracy and Readability

When it comes to aquarium water testing strips, you want the paper to be made out of very high-quality materials. This will ensure that the colors do not bleed into each other, therefore allowing for the highest degree of accuracy and ease of reading.


You also need to pay attention to what exactly the product in question tests for. Some of the most important parameters to test for include nitrates, nitrites, general hardness, free chlorine, pH, carbonate, and total alkalinity.
