Comments: API is a giant among companies that provide aquarium related products.They have maintained their sound reputation by offering innovative products and resisting the temptation to tamper with those which are already established and are time proven, dependable performers.The Fresh Water Master Test Kit belongs in the arsenal of tank maintenance and care products for every level of hobbyist from beginner to advanced.

It's important to understand that these kits provide an indication only - it's unrealistic to expect a pin point reading as the tests aren't intended nor made to deliver that. But rather, to enable you to get a decent reading of say, where your PH level is knowing the accuracy may be off a few points sure beats shelling out $200 for a good digital PH meter.It's critical to understand these limitations and that they apply to everyone of the four included tests.

PH

High Range PH

Ammonia

Nitrites

Nitrates

For must of us, Ammonia is the most important because it's the number one killer of aquarium kept fish. The others are important of course, but Ammonia levels should always be checked and checked often. It's also important to pay attention to the expiration dates of the liquid reagents. Expired reagents mean off the charts inaccurate readings. Along with the liquid reagents the kit includes, instructions both in a small manual and attached to each bottle of testing liquid, four test tube, four plastic caps and a color chart.

To ensure you get the most accurate reading possible compare the finished result to the card color block in the best possible light and against the most pure white background you can find. Just like computer monitors many of us see color differently which is the inherent draw back of this type of testing. But again, there is nothing else on the market at this kind of price point which can give you enough information to correct and adjust your key water parameters.

If you're just starting out in this wonderful hobby, you'll master using this kit in no time and it will help you maintain a healthy and flourishing aquarium. Remember to never, ever rinse even cleaned test tubes in your tank water - even very small traces of testing reagents can be lethal to your fish.

Draw water from your tank using a large plastic syringe available at any drug store, super market

Comments: I am glad they have something like this to test the levels in your aquarium. It's a great test kit, but the card is a little hard to match the colors through the glass test tube. Sometimes it is a guessing game, but you at least know the roundabout level if you cannot match it exactly you can match it between 2 colors. Overall, really good product, a must have for maintaining a healthy aquarium.

Comments: This is the best and easiest test I've found and cheaper than any other I've found on-line lots easier to read than the strips

<br />If you're just start

Comments: This kit has been giving me bad results for 3 of the 4 chemicals it tests. Really WAY OFF on the ammonia. The customer service Dept is currently arranging for a replacement kit. It was driving me nuts, as I have had aquariums for over 35 years, also cost me $25.00 for methods I took to neutralize what I thought was high (10 ppm) of ammonia. I did not lose any of my stock (Cichlid African tank 75 gal). I have never had this happen before with the API test kit.

Comments: Easy to use, and peace of mind knowing that I can check all levels in my small aquarium.

Comments: Accurate and Easy to Use

Comments: This kit is very complete. I like the glass test tubes and the cards. High quality. Beats those strip tests.
<br />
<br />Sometimes its hard to tell the exact color, but that could be my eyes as well.

Comments: This test kit is excellent. Everything is provided for you to test and monitor pH, Ammonia, Nitrite, and Nitrite levels. The directions are easy to follow and also provide some helpful solutions to fix common problems with your water. Also, it's much cheaper here than it was in my local pet stores!

Comments: Excellent test kit for all Koi pond owners and serious water gardeners. Also buy the GH/KH test kit and you will have every test you need to keep track of your pond. Easy to use, quick tests, no problems. As accurate as any drop type test kit available. I'm a KHA and I do lots of tests a year and tell others to buy these kits. You can use them for about two years and then renew. You can't go wrong!
