🐠 JNW Direct 9 in 1 Aquarium Test Strips for Fish Tank - 100 Strip Pack | Accurate Freshwater and Saltwater Water Testing | Test Hardness, Carbonate, Nitrate, Nitrite, pH & More Review

100. Not quite. More like 50. I'll have to double check because I'm getting different readings. I've stopped between the two and it does the job, but I'm still testing my big set just to be sure. For a quick read without having to lug around all the test gear, this is fine. *UPDATE* You've had some time and nitrates and nitrites aren't working at all anymore. They (I'm guessing based on their age) don't give real testimony. The color does not match any color in the list. Using my API master…

I have used two brands of 7-in-1 test strips and found them to be the most accurate compared to their lesser API Liquid Master test kit counterparts. The pH, chlorine, nitrate and nitrite readings were so "accurate" that I rely on them on a daily basis. found them somewhat inconsistent from package to package. I'm glad I found these from JNW, which mimic what Stript Health offers but are pleasantly more economical, especially with the 100 and 150 strips offered by JNW. is somewhat subjective…

Being new to this hobby I knew I needed a water testing kit to ensure my water was of good quality and free of contaminants for my fish. I ordered this before I really knew much about fish content. After starting my aquarium and using these test strips a few times all the results looked great. Then I noticed that a few of my little fish were turning black. After studying it more closely, I found that they had ammonia poisoning and my tank hadn't fully driven. I had to quickly order some test…

I've been keeping tanks for 30 years, I've used every test kit available, the cheapest is the Freshmaster API test kit. Other strips I've tried were at best 75% dosing or taking. These stripes are just awful! 1. no ammonia test. Which many manufacturers also do not include. Surprising why "Biggest Fish Killer" isn't included, but hey, they have a chlorine test, which doesn't matter since you'll need to use a water dechlorinator like Seachem Prime anyway. So they check other parameters, but as…

Just got it in the mail and compared 4 different solutions (tap water from the pit, rainwater that went into a food grade HDPE bucket after yesterday's rain, vinegar solution and baking soda solution). I also showed you how to compare the pH of tap water using these strips with my pH Test API Freshwater Master Kit. As you can see from my results, these strips are not accurate at all. They rate the free chlorine levels in my tap and rainwater as the same (they aren't), and they also rate the pH…

Overall I like the product but there are some significant flaws. I love the price of the product and the number of test strips you get which is 4 times more than other test strips for the price. You can clearly read the colors on the chart on the side of the bottle and it's easy to match the stripes. I'd like a printed copy of the e-book as a guide in the box it came in, but if you know what levels you need for your tank to get started then that really isn't necessary. The problem is that at…

So I think (as with all test strips) that individual tests are reasonably accurate. The most important thing about this monitoring is to follow trends and extremes, that's what they're good for. All strips are well cut (unlike some other brands where you can get a few half strips) with good spacing between test pads. The app is a good, albeit very basic, way of keeping up with trends and that was one of the reasons for purchasing this product. The app is very easy to enter indicator tape values
