Review: ACCURATE - I had always used test strips, but on using this liquid test, I found my strips were very inaccurate...by as much as 10ppm. Instructions seem a lot but after the first couple of times you will find it easy to use, and so much more accurate than the test strips. I keep Dwarf Rams and have a possible breeding pair, so accuracy of my water tests is important.
Review: API nitrate - Very good as described

## Questions & Answers

**Q: Is this test necessary and is it easy to use for a novice?  I received a 15 gallon as a present but I did not know it would be so much work and money.**
A: The test is easy to use; just remember to empty and rinse your vial after use, and rinse the vial with tank water (I dip some out with a small clean Dixie cup, then pour it into the vial and discard the water into the sink) before filling with water to do your test. And I examine the results under sunlight or a daylight spectrum fluorescent.If  you are doing regular water changes(weekly and/or as your water tests say to), and keeping the tank clean, you will not have to use this test often. Do not overfeed, and do not overload your tank (put too many fish or put too big of a fish in it). At the start you should have ammonia and nitrite test kits, and test daily to see what is going on while your filter cycles, then as a doublecheck for water quality. And yes it can take a month or so for your filter to cycle.Goldfish have a reputation for being a cheap fish, and easy to take care of... I breed and keep fancies; and honestly, 3 goldfish per 55 gallon aquarium!  A mature goldfish is about the size of an adult fist in body; and it is hard to keep water quality good for three that size in that size aquarium. In a 15 gallon no more than two small ones and they are going to grow and outgrow your tank. Half a dozen guppies or so will work, or a couple of mollies; or one betta.  Bettas need water about 85f, good quality, and at least a 10 gallon aquarium.

**Q: Hello I ordered this the 21st of April why is it taking so long to ship it ?**
A: Supply chains could be delayed due to Covid?

**Q: Does this include Nitrate Bottle #1 and Bottle #2?**
A: Ooops! Sorry. Yes it does include Bottle #1 and #2!

**Q: Putting 2.5ml & 5 drops of #1 & #2 each will get the same result? Will color continue to change after the 5 minute wait? Why cap leaks when I shake?**
A: Shake both bottles for one minute then add 10 drops of each to your test vial.  Then shake 30 seconds.   Any other questions should be directed to API. Not a consumer nor a seller

### ⭐⭐⭐⭐⭐ API nitrate
*by B***S on 23 August 2025*

Very good as described

### ⭐⭐⭐⭐⭐ Good test kit for nitratea - colour chart can be hard to interpret though.
*by R***N on 21 August 2025*

Good test kit for Nitrates. The colour chart is a little bit difficult to gauge but advice online seems to be to focus on the hues (orange/red) rather than the saturation. Turns out my tap water is 40ppm nitrate so this has made maintaining my aquarium a lot more...interesting!
