  • Good for quick checks!
Pattern Name: Aquarium - 100 strips
I’m a worrying person and these are perfect for quick checks throughout the week. No they are not as accurate as API test kit, but they can definitely let you know if something is seriously off. I looked at a lot of different types of these and found these and the Tetra strips to be the best overall rated. Tetra strips are more expensive though. I have had no quality issues and only a few issues with figuring out what color it was closer too. I found making sure you have a good bright light above is very helpful. I will continue to use these throughout the week until the give me a reason not to. ... show more

  • A Good Quick Look
Pattern Name: Aquarium - 100 strips
This test kit is a good quick test for your tank. This was able to alert me of nitrites in the water. However when using the API master kit it is very accurate, the test strips read about 1ppm nitrite and 10 nitrate, but it was around 0.25ppm. So not entirely accurate but it will definitely warn you if stuff is going on. The ph is decently accurate, on the strip it showed around 7.2, maybe between 6.8-7.2 and my ph on the master kit was around 7. The amount you get in the package is also good for the price, I bought API ammonia strips that cost nearly as much as this and didn’t even work. Definitely would recommend buying the master API kit if you want 100% accuracy but this is a good test kit. ... show more

  • Loving this
Pattern Name: Aquarium - 100 strips
I have three aquariums and I like to do occasional water checks, so test strips are somewhat of a hot commodity for me. Pet stores absolutely price gouge them, and after a while of that I found these for roughly half the price and triple the quantity. Tested them out (Pics above) and they worked just the same as any other strip would except for a couple extra squares that, while I think is cool to have, I'm likely never going to use. Cross referenced the readings with other strips, so these are just as accurate as any other test strips. What I like the most about this, though, is the price and the color chart. Starting with the color chart, other containers I've used have their color chart behind a layer you have to peel back in order to see it, so I shed tears of joy when I saw that this product has the chart easily visible without having to mess with anything. The chart also has very bold and clear markings around the safe areas. I've never had any trouble seeing the markings on other ones I've used, but it's a noticable improvement even to me. It might seem niche, but I can imagine if someone has vision struggles this could help with avoiding to strain their eyes. Now boy howdy, this price had me weeping like Jesus Christ just cured me of leprosy. The pet stores had fooled me into believing that theirs were only 'slightly' expensive at ~$20 for 30 strips. And then I thought I was getting away with HIGHWAY ROBBERY when I found a place that sold 30 for $13. Lo and behold, I find good quality test strips for the same price that I had thought was absolute bottom dollar, and it has more than triple the quantity! I don't know who Mr./Mrs. JNW Direct is, but I've named one of my fish JNW Jr. and I'm naming you as his godfather. So! Overall. Bad news is, I've got a nitrate problem. Good news is, after saving all this money, I'm a man who feels like a freshly made millionaire with a nitrate problem. This must be what it feels like to cry in a Lamborghini. 5/5 Stars. ... show more

  • realiable product
Pattern Name: Aquarium - 100 strips
Love this product. I tested against API water test kit for aquarium, and was spot on for PH, Nitrite, Nitrate & Chlorine. Which are the main ones to worry about with shrimp & fish. KH, GH and Alkalinity were showing a little above or below API kit, so not off by much. These strips allow me to do a quick check, twice a week to make sure nothing is off. Then when I do a 30-50% water change, I use API test kit as well. I also love the extra Copper & Iron test. I have planted tank so i need some iron but shrimp & snails, can't have copper and only little iron, so these strips are perfect. Thanks JNW Direct ... show more

  • Inaccuracy caused me to lose fish.
Pattern Name: Aquarium - 100 strips
I have been obsessively testing the water (several times a day) because it’s a new tank, all of the test strips have come out beautiful other than some high ph. This morning I woke up to 2 of my fish acting strange - lethargic, laying on their side but would swim away erratically if nudged. Of course I tested the water immediately, again the strip came out beautiful. Later in the day I unfortunately lost one of the fish and the other one this evening. I took the fish to my LFS as they offer a refund if the fish passes within 30 days as long as you bring a sample of the tank water they can test and it shows that the water parameters are within normal limits. They preformed the test in front of me and I began balling my eyes out when I saw there was high nitrites and nitrates. These test strips showed 0. I went and bought the API master test kit and tested my water. The one thing that these test strips showed me was that the pH was high, on the API test kit it was the only thing normal. Please if you are going to spend money on a test just spend a little bit extra money and time for something accurate so you aren’t unknowingly killing your fish. I did a good water change and I’m monitoring my other guys closely but I am truly heart broken over this. ... show more

  • Better than the Name Brand
Pattern Name: Aquarium - 100 strips
I bought these for my fish keeping husband to use on his fish tanks. He's really picky about his fish equipment and likes to stick with specific brands in his aquarium keeping. However seeing how much brand name test strips were we decided to try these as a cheaper alternative. My husband ended up liking these more than the brand specific ones he was using before. Not only are they a better price but they work well and do testing on nearly double of the components his old test strips tested. Would definitely recommend and will buy again when we're ready to replenish our stash. ... show more
