I LOVE API products and test kits however when I ordered my nitrate text kit it was missing a key piece of the kit…the TEST TUBE!My only issue with this is there is no way to contact seller AND it’s not returnable due to HAZMAT regulations.

These test drops are more accurate than the strips.

Works as intended. The instructions were super clear and easy to follow. A truly great product for our salt water tank.

I worked in three pet shops as a teen and later managed the slat water department in a very large pet shop in Philadelphia. I have kept fish since I was five years old but have been on hiatus for the past 20 years and not had any tanks.These kits have been around for ages and are very accurate if you use them for their true intended purpose; freshwater community tanks or similar. Don't try and use these the nitrite or ammonia for saltwater tanks of any sort. Don't use the pH test kit for tanks that need exact pH values for high pH animals like cichlids (though this is less of a problem if you read below). These tests are extremely economical and provide many more tests per dollar than any other kits available.My son is six and my daughter is four. We decided to raise tadpoles twice this year and needed to monitor ammonia, nitrite, and pH. The 40-ish year old design of these kits still fit that bill perfectly and were exactly what we needed. I wish the scale on the pH kit went higher, but it goes high enough for community fish. Tadpoles here tend to like higher pH values of ~8.2 and the pH kit doesn't go that high. However, I got a rough enough estimate if the pH test indicated that the pH was off the chart high as water isn't going to go much above 8.2 unless you use chemical inappropriately.Ammonia and nitrite test kits worked perfectly as in the past and averted many potential tadpole disasters and crying children. We've kept snails, clams, some minnows, and loads of plants in the tank while the tadpoles have developed so the bio load was always changing.Still great kits even after 40 years at a very affordable price.Highly recommended for their intended usage scenario.

API kits are fairly accurate for the price, I highly recommend them for salt water aquarium owners that need and should have at least 2 kits of every important test type so they can cross reference results if they feel something is wrong with a particular test result. API fills that niche perfectly with pretty accurate easy to use kits that cost a quarter the price of the more accurate ones like Salifert, ELOS and Red Sea Pro.The API Nitrate Kit is as simple as it gets, just fill the vial to the marker or better yet use a syringe and add 5ml as directed. Then add 10 drops of reagent "A". swirl for a bit then shake reagent "B" for 30 seconds very vigorously and add 10 drops of that. Shake the whole thing for one minute vigorously and then wait 5 minutes to get a result.IMPORTANT NOTE: If you forget to shake reagent "B" you might as well throw the whole bottle of reagent out. This solution separates out in the container after a few hours into layers of different chemicals. If you don't shake it, you will be dripping out 10 drops of just one of those chemicals and remaining mixture will be compromised. The end result is that the next time you use it and shake it up properly the typically result is a lower reading than normal. Just remember to always shake reagent B properly for 30 seconds and you wont have any problems.If your Nitrates go down to reading Zero on the API kit, then it's time to move to a more accurate kit that is designed to read very low Nitrate levels. If your keeping a SPS Reef Tank you need the Nitrates to be near Zero and the API kit will not be accurate enough to read the small amounts that may be in your aquarium. For FOWLR Tanks, Nitrate is not as not as big of an issue, so an API kit or two is all you will probably need.

I went to the local fish store and purchased the Ammonia and Nitrite test kit (both look identical to this one, bot by api) for my new aquarium. They were sold out of the Nitrate and Ph at the store so I went to amazon and picked these up. I wish I would have looked on Amazon ahead of time! API sells a master test kit with all four of these tests (ammonia, nitrite, nitrate, and ph) that I bought individually for only $20!! So if you're new to aquariums or you're setting up a brand new one with no idea how to test water quality - I would definitely pick up the master kit. It has everything you'll need! With that said, this single test kit performs flawlessly. These API test kits are the best that money can buy. They're super cheap and theres enough liquid to last a long, long time.This particular test kit for Nitrate has a much more detailed and precise set of instructions than the other test kits they offer. Its not as easy putting a couple drops and shaking like the other kits. However, its not much harder either. Nitrate is a tricky thing to measure accurately, just follow the detailed instructions and you'll get accurate results every time. My toddler can test the water accurately - so can you!
