This product is excellent and provides very quick and accurate results. You just need to follow the instructions as per the manual and the test results will come quite accurate. The box includes: 1. Chemical reagents to perform all the tests mentioned - PH, High PH, Ammonia, Nitrite, Nitrate 2. 4 Test Tubes 3. Manual and Color chart The color chart is very helpful and the manual explains very clearly how to understand the results based on the color. The PH results come immediately. For Ammonia/Nitrite/Nitrate, you need to wait for 5 minutes. In a well cycled tank - Ammonia and Nitrite must be 0ppm(VERYImportant) and Nitrate also within acceptable limits. This is a must for any aquarium and specially useful for any new tank setups where you need to monitor the water conditions regularly during the cycling process. Based on the results, you can take decision for water changes. Best Master Test Kit available !!!! Go for it.

You will find this freshwater kit is far more accurate than test strips. The soaking of a tiny doped pad method of test strips just isnt an accurate way to test. This is the industry standard water test kit that most aquarists swear by. 1st, be sure the test chemicals you get are not near expiration. You should easily be able to use this kit for up to a few years before the chemicals included lose their effectiveness. The expiration date is on the kit box and on each bottle of solution. The glass test tubes that used to be included in this kit have been replaced by plastic ones. The glass tubes made cleaning up a breeze and were far better than the plastic ones that don't clean up as well. Also the 5ml fill line is a bit difficult to see on the plastic tubes. It was always inevitable though that you would eventually break a few glass tubes before you got through the 800 tests this kit can provide. They now just assume that by the time the plastic tubes get permanently stained, you'll be on to a new test kit with new tubes. While not a deal breaker, I prefered the glass tubes. Be sure you purchase the kit best suited for the tanks or ponds you keep. This kit is the freshwater version. This kit tests pH in two different ways. If you have ph generally higher than 7.4 you use the high pH test solution. If you have pH below 7.6 youll use the standard pH test kit. This is great of you are keeping multiple tanks with different pH levels or if your one tank tends to bounce around between 7.4 to 7.6. Once you figure out which test best suits your aquariums, youll likely not use the other solution. This kit tests for total ammonia using 2 solutions in one test. Ammonia is a very hazardous chemical to your fish and plants. Use this kit to keep these levels of ammonia at or near 0. This kit tests Nitrites using 1 solution. This is the second step in the nitrogen cycle. While not as harmful as ammonia, it's still something you should strive to get as close to 0 as possible. Now some people using heavily planted and fertilized tanks will actually strive to have this level low but present. This kit tests for nitrates in two solutions for 1 test. While nitrates are not as harmful to fish as Ammonia or Nitrite, most fish keepers still strive for low readings. Long term exposures to high nitrates can still cause harm to fish. Generally youll get rid of nitrates by water changes or heavy plant growth. Many people with heavily planted and fertilized tanks prefer this value to be a little higher to feed the plants but still low to protect the fish. With this test kit testing 4 of your most important chemicals in fresh water, it is a necessity to have on hand. Test strips might be more convenient but are seldom very accurate. This liquid master test kit is the standard if you want true values at an affordable price. It comes in several varieties, depending on whether you have freshwater, marine, reef or ponds. Its a great way to see what is going on in your setup before any loss of life occurs.

There is a reason why this test kit is considered the best amongst aquarists and fishkeepers. It is more on the pricey side and there are definitely more cost effectivr kits in the market. However, it very simple to use and the instructions are easy to follow. Highly recommend this kit for individuals starting out in the hobby as testing the water is essential for keeping your fish alive.
