Most water problems are invisible to the eye. Quickly measure and modify the six aquarium levels that are most important to the health of your freshwater fish with the API FRESHWATER MASTER TEST KIT. To stay healthy and thrive, fish need properly balanced levels of ammonia, pH, high range pH, nitrite, and nitrate. These levels can change rapidly and create harmful conditions when fish waste, uneaten food or other organic matter accumulate, or when untreated water is added.<br><br>If left uncorrected, all of these can be harmful or even fatal to fish, with consequences such as reduction of oxygen, increase in stress, and higher risk of disease. The API FRESHWATER MASTER TEST KIT measures these six parameters with scientific accuracy and provides professional results. It comes with four glass test tubes, a holding tray, a test tube rack, and computer calibrated, laminated color card.<br><br>Just fill the test tubes, add the test drops and compare the results to the color card. Then follow the recommendations on the card if action is required. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium.

[This review was collected as part of a promotion.] The API Freshwater Master Test Kit has been super helpful for checking on the ph-water level plus other levels in the various aquariums that our turtle & fish are currently occupying. The instructions are easy to read plus the test tubes & container are made of very durable material. I check on my pets throughout the week to ensure that they are in the healthiest environment where they can to continue to grow & thrive. Also, after I've finished testing their water, disposing of the mixtures is easy. I was able to clean up in minutes.

API Freshwater Master Test Kit is a necessary in your stash for any aquarium owners!

love this test kits. works great. I had been using the straps and they always read something wrong. This kit is a good way to test and trust

walmart.com

I was using another brand dry strips (not impressed)  %26 read to try API Master Kit. A big difference.  Company does great job explaining why you do the specific tests %26 how to do each test.  I very much like on each solution it again lists how many drops you need. Very  nice case for test bottles %26 drops.  Will buy again.

API Testing is a great kit.

[This review was collected as part of a promotion.] I have about 500 gallons total between 6 aquariums.    API is my go to testing kit.  It is accurate from freshwater to saltwater and everything in between. It is the best deal out there for beginners up to experts and covers all the basics you need to know if you want to keep your aquariums in good health. The design of the container itself is handy and helps to jeep your tests organized.

Easiest test kit out there.

Great overall set that helps with my aquarium.

great for my axolotle

Great

Says it will arrive on one day but shows up many days later, product itself was good.

It comes with a lot of hassle, and dipping, and DRIPPING, and measuring, and waiting.. 😞 
After finding the results I'm getting by using the test kit, I have decided that test strips are very dependable and really pretty much nail it for my needs.
I am actually beginning to believe that it's not necessary to get "overly, overly freaked out' about all your levels in your aquarium. First and most importantly, start out by using reverse osmosis water in your tank from a reputable source. Even the water coming out of those machines in front of the stores is much better than tap water. I checked that out with my test strips also... But try to get it from a water store. test it with your test strips before you put it in. It should be pretty pristine on all the levels presented on the stick.. It might be a little low on pH
R. O. water is a huge plus, right there. 
Secondly, you can look at the fish and see how they are functioning. You can read up on Google as to how your fish should be behaving or not behaving.. Are they clamping their fins.?? Yeah, you have a problem.. Are they staying away from the bottom, or always floating way near the top? Yeah, you may have a problem..  otherwise, if they seem to be happy and they seem to be healthy looking with no funky disease spots or anything like that, I would say your aquarium is a pretty happy place. Definitely do water changes.. Good ones.. Once a month. keep it scrubbed up inside. Make sure the temperature is good in your water for the type of fish you have. But don't get too overly concerned about it all. Constantly messing with it is not good, either. DEFINITELY have good frilltration. WAY over the top with the water cycling, as much as possible. Lastly, read up on how to take care of fish. Become knowledgeable and familiar with your hobby. Knowledge is power when it comes to taking care of fish. But don't get TOO  over- picky about it all, as I stated before. GOOD LUCK!
