Im very pleased.
Great easy way to test everything. Great price. Easy to read and fast. I will buy more.

Used for new saltwater tank
Iâve only used one strip and it appears to work. The colors are vibrant and close to the color keys

simple to use, fast
I compared these to api test strips and they fall firmly in the “close enough” range. Hard to really know which one is right when you only have two options.These are super easy to use that even my 10 year old daughter does. Great to keep tabs of the water quality and not have to spend a mint.

Great Product
Product arrived quickly and is very easy to use. Easy to read colors and a broad range of parameters covered by the tests on the strip. I will continue to order more in the future.

Good Overall, But One Test is Off
Iâve been using these test strips for a while now, and for the most part, they do exactly what theyâre supposed to. The readings for pH, chlorine, hardness, iron, and copper seem to line up well with my other test kits, and the convenience canât be overstated â just dip, wait a bit, and compare to the chart. That said, the nitrite reading consistently seems off, especially when cross-checked against my API liquid test kit. Itâs not wildly inaccurate, but itâs just enough to make me double-check it every time. Still, for the price and the amount you get (120 strips is a lot), theyâre absolutely worth having around â especially for quick, routine checks when I donât feel like setting up a full-blown liquid test. If youâre managing multiple tanks or just want something fast and mostly reliable, these are a solid choice. Just donât throw out your backup test kits entirely.

Inconsistent and hard to read
I donât feel like these are reliable at all. I always use the tetra brand but I wanted ones that tested more components, and the readings on my tetra strip actually change over time as water changes are due, however no matter what I did to my water when testing these, many areas such as PH, KH, and total alkalinity read pretty inconsistent. These were all done back to back. The color similarity between different levels are also so similar so that doesnât make it any easier to try and read. All in all pretty disappointed after doing a lot of review reading before picking these

Distinct vibrant colors make it very easy to interpret!
This set of 120 test strips is a must-have for any aquarium owner. It measures 9 crucial water elements, including pH, carbonate, alkalinity, total hardness, chlorine, copper, iron, nitrates, and nitrites. Itâs perfect for maintaining a healthy tank, though it’s important to note that it doesnât test for ammonia which you should be testing for separately if you have an aquarium.Packaging: The packaging for these strips is very thoughtful. The container is compact and convenient, and the instructions along with the color scale are printed directly on the bottle, allowing me to discard the box without losing important information. The strips feature a long section for easy handling, and the color scale aligns well with the test indicators, making it straightforward to read the results.Usage: Using the strips is simple; just dip them completely into your water sample for 2-3 seconds and read the results within 15 seconds for all but the nitrate/nitrite which you read in 60 seconds. The instructions are printed next to the scale making it easy to remember which ones to read first. This is such an important detail since the most important factor for incorrect measurements is not following the instructions!Reading: The color scales for these test strips are honestly one of my favorite aspects. They feature vibrant colors that are easy to read in different lighting conditions. One of the most frustrating aspects of some other test strips is when it is difficult to differentiate between colors on the scale. The scales on this test strip all run a wide range of color hues or intensities, making it easy to identify which value it is measuring.Accuracy: I tested these strips against my API kit which measures pH, nitrates, and nitrites and found the results to be fairly consistent. I also tested my water before and after adding a water conditioner, and it did pick up on the change in chlorine. Overall, itâs a reliable and user-friendly kit for maintaining your aquarium.

Quick and easy to use, Peace of mind in less than a minute
These test strips are awesome! I just got in to doing aquariums, I only have two small ones at the moment, but I wanted to make sure I did right by the Bettas I put in each one. These test strips are simple and straightforward to use, the color key is printed right on the bottle, and the test takes 1 minute to complete. The results are easy to read, and when I took a water sample to the pet store they got the same results I did with these test strips so I would say that they are very accurate as well. Great value for the price, there are a lot of test strips in the bottle!
