What is an Aquarium Test Strip?
The aquarium test strip is one of the most essential tools in fishkeeping. With an aquarium test kit, you are opening a window to the undervalued and invisible world of tank water quality.
Sadly, some fishkeepers take water testing lightly until something wrong happens in their tank.
Aquarium test strips and kits are designed to monitor and maintain the levels of elements inside your tank. These elements usually include magnesium, iodine, pH levels, carbon, nitrates, nitrites, ammonia, and many more.
Even though they are not harmful to humans, these elements can be dangerous and even fatal for your fish.
Since we mostly use tap water for our aquariums, these test strips ensure that the tank water is safe from any harmful elements.
These test strips, however, do more than just prevent an aquarium disaster. Aquarium test strips also let you fine-tune your aquatic ecosystem or environment, allowing your invertebrates, plants, and fish to look absolutely stunning.
As you use these strips, you may even add some algae-promoting minerals to make your aquarium look cleaner.
Types of Aquarium Test Kit and Strip
Various kinds of aquarium test kits and strips will help you maintain a healthy and thriving aquarium. Here are the most common aquarium test kits and strips.
Master Test Strips
Master or combination test strips are often deemed as the ultimate test kits since they provide all the tests you need for a healthy aquarium. These combo kits cost lower per test and are an easy way to keep all the basic and essential tests at once.
On the low side, some of these kits do not have customizable test options.
Alkalinity Test Strip
This test kit is used to find out the stability of your aquarium’s shift of pH levels. The ideal reading should be around 7 to 12 dkH.
pH Test Kit
This test strip gives precise readings of the levels of alkalinity inside your tank.
Calcium Test Kit
With this kit, you get to introduce appropriate levels of calcium, helping the growth of your corals.
Ammonia Test Kit
Ammonia is one of the leading causes of death for domesticated fish in aquariums. The reading and ammonia presence on your tank should be totally zero.
Chloramine Test Kit
This testing tool is built to determine the level of chloramine, which is a compound combination of ammonia and chlorine.
Copper Test Strip
Copper is usually present in tap water that goes through old copper pipes. Since this element is not needed by fish, it should be eliminated from the water before it is poured into the aquarium.
Chlorine Test Kit
Chlorine is pretty abundant in tap water because it is commonly used for killing bacteria and disinfecting the water. Unfortunately, it is a harmful element for your fish.
But, a chlorine test kit will let you monitor the level chlorine in your tank, helping you create a safer environment for your fish.
Magnesium Test Strip
Natural saltwater has a magnesium level range of 1200 to 1400 ppm. With a magnesium test kit, you will get to maintain the ideal magnesium level for your saltwater aquarium.
Iodine Test Strip
Iodine is a vital nutrient for invertebrates, corals, and other saltwater tank organisms. Iodine overdosing, however, can be deadly to them. That is why you should check your saltwater aquarium’s iodine levels using this test kit.
Nitrite Test Strip
Nitrites are lethal for fish, so this test kit will help you maintain the perfect nitrite levels of your aquarium. Ideally, nitrite levels in your fish tank should be zero.
Nitrate Test Kit
Nitrates may not be as dangerous as nitrites and ammonia, but can still be pretty harmful to your finned pets. This aquarium test strip lets you maintain the ideal nitrite level (less than 20 ppm) in your aquarium.

How to Find the Best Aquarium Test Kit?
Budget is, for most aquarists, always a given, as far as making a purchase of any item. So, it is best to explore more on the other aspects as you look for the best aquarium test strips.
Ease of Use
Look for the best aquarium test kit that is not complex and puzzling. Simply and easy-to-use packages require minimal effort and time to obtain the results.
Sophisticated test strips, on the other hand, tend to consume more time and even require a bit of effort and knowledge before they provide precise results.
Do you need a comprehensive reading tool or something with pinpoint accuracy? Since the life of your fish depends on the elements in your aquarium, you should look for a kit that provides the most accurate readings.
Luckily, most of the best aquarium test strips have a long lifespan. While it will expire eventually, its lifespan will still depend on the kind of strip.
An aquarium test strip with a high pH range value is likely to last longer than a typical ammonia test kit because of the chemical nature used in these things.
Also, expiration dates are dependent on usage and normal storage conditions.
