Top 15 Best Aquarium Test Kits and Strips in 2023

Keeping healthy and balanced aquarium water is, no doubt, the key to a thriving aquatic environment for your finned pets. While there are a few other components to monitor in your tank, you should definitely test the water of your aquarium every week.

Trust me, it is the most effective way to quickly determine when something is not right. Furthermore, it can help you figure out the issue when your aquatic pets begin to exhibit some odd behavior.

And, to make that you are creating a healthy aquatic ecosystem possible, you need to score the best aquarium test strips.

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.
