Does this kit give us what is needed to correct the problem it discovers or do we purchase that separately?
Answer by ChewyNov 04, 2018
This kit is specifically designed to measure, modify and balance the conditions of freshwater aquariums.

How many water tests can you get out of one kit?
Answer by ChewyJul 28, 2017
This kit includes 4 test tubes with snap-tight caps.

Will this test kit let me know if there is chlorine present? I'm a real noobie.
Answer by ChewySep 13, 2021
This test kit does not test for chlorine level. This kit measures the 4 most important levels in freshwater aquariums quickly and accurately, including pH, high range pH, ammonia, nitrite, and nitrate.

What's the difference between "fresh water pH", and "high range pH"?
Answer by ChewyJun 19, 2019
The pH Test will be able to read a pH level between 6.0 to 7.6. When keeping livebearers, goldfish, African Cichlids or marine fish & invertebrates, the High Range pH Test should be used. High Range pH Test will be able to read a pH level between 7.4 to 8.8.

A must have for fish keepers

I have been in the aquarium hobby for more than a decade. If you are going to keep fish then you have to know the nitrogen cycle. It is the single most important thing. This test kit is a must have. It is the best thirtyish dollars you will ever spend. This test kit allows you to monitor your ammonia, nitrite, nitrate and pH levels. When setting up a tank you will need to test daily. Once the tank has been running for a while and the nitrogen cycle has happened in full you can test less frequently. Yes you can but the test strips to tell you everything this kit will do but the strips are much more expensive in the long run.

Testing tank water

As advertised

Very nice kit. Gives you everything you need to get off and running. Easy to use. I only wish they could get the price down some so more people would use them and more fish would be protected.

Happy fish

The kit is great. It's easy to use. The only suggestion I have is to include an eye dropper to make it easier to get the correct water level.

perfect for people who care about their fish:)

Extremely easy to use, with a very informative booklet. Even if you're a beginner and words like "nitrate," "nitrite," and "pH" scare you, you'll be able to get comfortable with this. This kit definitely isn't some menacing demon back to haunt you from your high school chemistry class. It's unbelievably easy to use and understand, and, above all, it might even save your fish:)
