Testing the Waters
In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. Most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly. Testing aquarium water weekly will aid in keeping your most important water parameters within the proper range for your aquarium. Choose from a wide range of API testing options, such as our popular FRESHWATER MASTER TEST KIT or 5-IN-1 TEST STRIPS, for accurate water evaluation. Regular testing will help you easily determine your aquarium conditions.

Please Read Instructions Before Use
Nitrate is produced in the aquarium by the biological filter. Beneficial bacteria in the biological filter convert toxic ammonia and nitrite into nitrate. A high nitrate level indicates a build-up of fish waste and organic compounds, resulting in poor water quality and contributing to the likelihood of fish disease. Maintaining a low nitrate level improves the health of fish and invertebrates. Excessive nitrate also provides a nitrogen source that can stimulate algal blooms. Aquarium water should be tested for nitrate once a week to ensure the nitrate does not reach an undesirable level. This test kit reads total nitrate (NO3) level in parts per million (ppm) which are equivalent to milligrams per liter from 0 – 160 ppm.

After 2 weeks of 0-.25 readings without fluctuation, I wondered if the tests were even accurate. I decided to test 5ml of pure ammonia instead. Imagine my disappointment when the pure ammonia sample turned the same yellow (0%). Before you go sending hate mail to API, there's a good reason for this. It turns out, the ammonia level was too high and essentially "blew out" the testing liquid. API is assuming your fish isn't living in pure ammonia and, therefore, didn't make this kit to test levels that high.
Next, I tested 5ml of water from a 1 gallon jug filled with tap water and 1 drop of pure ammonia. Yes, I apparently have too much time on my hands and a latent mad scientist gene. This test proved accurate. The tube turned dark green almost instantly (picture attached). I feel much more secure using and believing this test now.
Here's the thing though: a few years ago the freshwater color card (used to read the NO3 level) went from having 7 clear colors to choose from to having a muddled mess. At the low end of the range (where you would want your water to be), the colors are clear and decipherable. At the middle part of the range (where I tend to find things a bit too often), the colors start to look the same. Maybe it's just my eyes. I can see subtle variation between 10ppm and 20ppm and between 40ppm and 80ppm, but it's not enough to tell the difference when actually performing a measurement. Instead, I just split the difference and go with a generic "orange" is 15ppm and "red" is 60ppm. I can still pick out an intermediate "red/orange" that's around 30ppm, but I'd appreciate having a real color card capable of full resolution.
The API test instructions - up to the point where you read the results - are clear enough. However, they don't tell you the best way to read the colors, which is the most important part of determining your phosphate levels, and this method goes for any such color-reading tests. DON'T lay the test tube against the color chart to compare the colors. Doing so will give you false readings (makes them darker). Instead, hold the test tube parallel to the chart and adjust the distance (about a half-inch away) from the chart until the color is uniform within the tube. Be sure to hold the chart at an angle that shows the colors on the chart best, while comparing the colors.
Many reviews complain that this kit doesn't test very low phosphate levels, and they are right. However, there are reasons to want to test for high phosphate levels ranging up to 10 ppm. For those that want to differentiate between fractional phosphate readings below 3 ppm, get the Salifert test kit. I use both, but in a planted tank using the highly regarded Estimative Index approach to fertilizers, you will often find phosphates going much higher than the 3 ppm upper limits. In a planted tank, you should not be concerned about trying to achieve low phosphate levels. You should be concerned about achieving balanced phosphate levels and that means phosphate readings in the 3-10 ppm area can be ok. Algae does not expand simply because of high phosphate levels in a planted tank.
EDIT: After letting the test tube sit for an entire day, I can actually distinguish a copper reading that seems to be nearly accurate with the amount of Cupramine I dosed. I tested ANOTHER sample of the same water, and got copper color immediately? Both tests look identical and it is actually reading right about 0.5mg/L. I am not sure if I should trust the readings, although they would be spot on with the amount of Cupramine I dosed. I'll test it with a Seachem test kit tommorow and update this review. Also make sure to follow the directions precisely, you need to remove the cap and look down the test tube with the white background of the color under the tube, but don't let the tube sit directly on top of the card, the color will appear much darker. Hold the test tube above the card an inch or two.
EDIT #2 02/19/18: The Seachem Copper Test kit arrived and the results are in: 0.5mg/L. Right at the amount I dosed. Tested again today with also the API Copper Test kit. Results again, are the exact same. 0.5mg/L. This means (in my case) both the API Copper Test Kit and the Seachem Test Kit are both precise measuring tools if you are dosing Cupramine.

Update: the drop size for bottles 1 and 2 are very different, such that bottle 2 ran out long before bottle 1 was empty, making the kit useless. This does not appear to be a one-off either, because the exact same thing is now evident in my second ammonia test kit!
Test detects small amounts of nitrates quite well.
On the photo is result of tap water in London before and after filtration. Pretty high nitrates! But are they 40, 50 or maybe over a hundred?
I tried testing it with a few things:
- water from my freshwater aquarium
- water from my saltwater aquarium
- tap water
- bottled water
- dirty water with a lot of ammonia (I put some flake fish food in some water and let it sit for a while)
All of them with the same result.
This works and it appears to pick up even trace amounts.
Distilled water has none according to this kit just as you would expect,
Tap water has just the tiniest amount, so it's good to know it can pick up such a small amount.
