Chewy purchase
Test kit arrived on time with my other purchases. This is a tough one because I have no way to check the voracity of test results, but it works just as advertised.
Not sure there wirth it
Easy to use but they don't check ammonia levels and there nitrite and nitrate readings are way off from the regular Api liquid test. Use with caution they do not give reliable readings. The Gh readings were a nice find but they maybe off as well
Aquarium Test Kit Review
The kit worked fine but is not like the kits I usually use. This kit, you need to look up the normal range results to see where your test results lie. The ranges are shown in the pamphlet included with the kit. On the kits I usually use, they show the normal range right on the gauge. It is so much easier.
Bit confusing
The instructions say immediately check the first 3 indicators but to wait 30 seconds to read the 4th & 5th/nitrite and nitrate levels. I bought these to test my nitrates specifically but the reading continues to change (get darker) after the 30 seconds. So what's the correct level; the reading at exactly 30 seconds (could be 40 to 80) or the color it ends up at (as high as 160)?
Works 90% of the time
These strips are decent for in between using a full drop test kit like the API Freshwater Master Test Kit. I do find about 10% of the strips I used had issues with the pH portion not developing properly, thus not being able to read the results.
master test kit is better
The product said I had high nitrite in my 65 gallon aquarium and then I was worried so I ended up buying a API master test kit and I had no nitrite, I couldn’t believe how bad of a product and waste of money this was.
Good Product, to an Extent
While these dip sticks come in handy, it’s important to use a fresh water master test kit to get PRECISE values and read your water for ammonia (since these DON’T test for ammonia). These are handy for in-between precise water tests, but not as the only source of water testing, because they aren’t incredibly accurate. I attached a pic of their master test kit that i use, just in case. API is an excellent brand!
Unfortunately inaccurate
I got these to easily test my kh and gh as well as a quick check on my nitrates so I don’t have to pull out my liquid test kit every week... well in a side by side comparison of the pH and nitrate, the strips were way lower on both tests than my liquid tests. Showing the nitrate as an example. Now I’m not sure I can even trust the kh and gh measurements.
Great item
I have a 28 gallon aquarium and use the strips atleast twice per month to check the water. The strips work very well and are super easy to read.
Aquarium test strips
The instructions aren't really clear, and the sheet doesn't really explain what the paremeter readings mean, I'll probably just end up taking a water sample to the local pet store and hope they acctually know what they are doing.
