API FRESHWATER MASTER TEST KIT 800-Test Freshwater Aquarium Water Master Test Kit, White, Single, Multi-colored

Easy to understand the instructions. Comes in a portable case which is a perfect caddy to go from one aquarium to the next. No scent that I detected. The case is durable and has an easy storage system that holds each vile. The colors are easy to get a reading to match against and each bottle has a different color for color coded instructions. The helped me adjust my water parameters to better suit my tropical fish. Very effective.

This kit will last you a while, the material is good and it is very simple and easy to use. It doesn’t smell bad at all.The tubing is plastic, and I recommend handling with gentle care because you can rip off the lids if you mis treat it, but other than that the whole kit is good. The color comes out pretty precise, and the instruction manual tells you everything you need to do especially for people’s first time using it.Personally in the back of the book there are blank pages, and I like writing the date and the results every time I water test. Just a little tip!

This is a crucial need for EVERY aquarist out there. This kit is worth the time and money and it lasts me foreverrr. Will forever be buying refills. This kit is so beneficial in cycling your tank and checking for ACCURATE water parameters. It’s easy to use and I love feeling like a scientist when testing. Will forever recommend this product to those who need it.

Got this kit for monitoring my goldfish tank. Very easy to use with clear instructions. Overall very satisfied and think this is a very suitable test kit to start with.This kit tests for 2 things. (1) PH levels and (2) Ammonia, Nitrite, and Nitrate levels (i.e. the Nitrogen Cycle). The Nitrogen cycle as related to a fish tank is as follows...Your fish gives off waste products, which Ammonia is a major component. When Ammonia levels in the tank go to high the fish can get burns, sick and can die. At some point your tank should develop bacteria that convert the Ammonia to Nitrite (this bacteria can live in the gravel and the filter. Also this bacteria is killed by tap water that has chlorine present so this is why you don't wash gravel with tap water. Also this is why you should not change all filter elements at once as you may be eliminating too much of your bacteria colonies). Once the bacteria that do this develop a large enough colony your ammonia levels should go to zero. Before the colony of bacteria is developed your tests for Ammonia should show some level present. You want to make sure that the level does not go to high. To reduce Ammonia levels you can either do water changes, use a filter that removes Ammonia or there are additives that can be added to reduce the levels as well.The next step is the bacteria converts the Ammonia to Nitrite. Nitrite levels if they go too high are bad for fish. Initially Nitrite levels will tend high (similar solution for excessive Ammonia levels will work for Nitrite as well). Eventually a colony of bacteria will develop that convert Nitrite to Nitrate. Once the colony reaches maturity your Nitrite levels should come up as zero on your tests.The final step (well not final if you use plants, which is more complicated) is as mentioned above the Nitrite being converted to Nitrate. When the bacteria colonies are fully removing all the Ammonia and Nitrite the tank is called cycled. At this point the major concern is that Nitrate levels should not go too high. The fortunate thing is that fish can tolerate relatively high levels of Nitrate as compared to Ammonia or Nitrite. I would think most cases where fish are not faring well, probably the Ammonia or Nitrite levels are high and the Nitrate is fine. In any case you will need to test for Nitrate probably no more frequently than every few weeks to few months (depends on your tanks size and number of fish) to make sure the levels are not getting to high. The solution for high levels is the same as for Ammonia or Nitrite, namely water changes, filtering, and additives (I have stayed away from additives but they are an option).This kit gives you everything you need to test for this critical cycle and is probably all you need for most fish tanks to help you keep your fish healthy for a long time.

It's a must-have for aquarists and it's very accurate, but i think buying the test strips are more convenient and quicker than breaking this out every time. I only bought it, since it was on sale

Does this scale look a little wonky to anyone else? The 7.6 and the 7.4 seem to be out of order, but also the color gradation jumps dramatically between the ones labeled 7.6 and 7.4. It's almost like the labels were printed backwards?Edit: I'm dumb. those are two different ph test scales. There are two separate PH test reagents.All the tests seem to work just fine, and after realizing my mistake, the color chart is fine. There are still some typos and incomplete sentences in the instructions, but everything was still clear enough to follow.I'm gonna have to get an alternate pH test for a sanity check here.which doesn't inspire confidence for the rest of the test get either, as well as the typos and incomplete sentences in the instruction manual.at least it is cheap and it's giving me some metrics to go off of.

If you're even just getting into the fish keeping hobby, this is a must have. In my experience test strips are inaccurate and spotty at best, but with this Master Test Kit from API is effective and you will know what is going on with your tank. I only wish this test kit included the GH and KH tests as well but they are available to buy separately.

Saves me so many trips to the pet store. Super easy to use, easy to clean. Directions are very clear. A must have for anyone with even 1 tank. It's worth the $, you will use it a LOT before you need to replace the drops. I've had 6 tanks at once over 2 years and still had 1/2 my drops.

I moved away from test strips and bought the API 800 Test Freshwater Master Kit. One of the best decisions I have made for my aquarium.Test strips may look convenient but once the container is opened and the strips are exposed to air the clock is ticking. Moisture and oxygen start degrading the reagents immediately. After about 30 days the accuracy drops off badly. At that point the readings are questionable and you may as well consider them unreliable. For something as important as water quality, that simply is not good enough.The API Freshwater Master Kit solves that problem completely. The reagents are stored in sealed bottles so they remain stable and accurate for a long time.Using it is straightforward. Fill the test tube with tank water to the line, add the correct number of drops from the bottle, cap the tube and shake. For nitrate there is a second bottle and a longer shake but it is still very simple. Wait the specified time, then compare the colour against the chart. That is it.What you get in return is far more reliable information. The colour changes are clearer and the scale is more precise than strips. You can properly track ammonia, nitrite, nitrate and pH rather than relying on vague strip colours that can be difficult to read.Each kit also lasts a very long time because you get a large number of tests from the bottles. It ends up being far better value than constantly replacing strips that degrade quickly.If you want accurate, repeatable readings and a clear picture of what is happening in your tank water, this kit is excellent. Simple to use, dependable and well worth the money. Highly recommended for any serious fish keeper. 🐟

Excellent Quality. Accurate test result. I recommend this product. Delivery recieved early

So easy to use , very accurate , the test strips said everything was fine but this master test kit told the truth it wasn’t fine and it helped me fix my water so my fish stopped dying , would definitely recommend for everyone keeping fish !! Definitely worth the money it’s actually not much when you think of it this stuff will last forever , I think it said 800 tests ,you only uses so many drops per test and you only need to test once a week unless you have a problem your trying to fix ..

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, Nitrate2. 4 Test Tubes3. Manual and Color chartThe 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.

Very good for water testing and very accurate
