"Bought the 100 Count."And if it was, please click on the helpful button below. Very good instructions and a comparison color chart. I take every precaution about the chlorine, and trust the strips for everything else. They show results, what is safe& not safe and what to do if not safe. I wish there were a simpler accurate test for it. I don't know so much about how precise these are. If this review was helpful, please click the helpful button!

Fluval A7551 Final Thoughts
"Maybe I have bad bottle."The kH pad sometimes has the same problem as well. They test pretty accurate when run against my chemical tests. They show results, what is safe& not safe and what to do if not safe. This kit is extremely accurate and very well designed for convenient use and storage. Wasn't labeled that way in the descriptor. This is a good kit so much more accurate and easy to figure out how to use it. Also, I'd avoid Tetra's strips to be honest- the reviews speak for themselves.

- ✔ EASY TO USE --- Simply sample your aquarium’s water with a spoon and dip one of our test strips in. Then remove and in 5-10 seconds the test strip will reveal your water’s pH.

SunGrow Final Thoughts
"Strips work great!"These strips work very well and I have had consistent results with them. If you're looking for a quick-hit on a range of water quality these are the answer. My 12 yrs old son wanted a fish tank so we got him 2. I tested the water and the nitrates and the ph were pretty high still. Some of the readings develop better than others. My tap water actually was really green and was a very close match to the 1. It looks to have the slightest green tinge but is not as green as the 0.

"Simple and easy to use."6 showing the test strip as an accurate reading. So I got these to try and I love them. Wasn't labeled that way in the descriptor. Before, I brought water into a pet store, but kept seeing no signs of improvement. If I had a complaint, I wish the color legend was printed on the bottle. They show results, what is safe& not safe and what to do if not safe. They showed the same results as these for the sites they had in common.

"Love the convenience."Very easy to use and very easy to read test strips. The nitrate test is a little finicky as most users will agree. Tank lids, water additives and more have seen the same effect. I even got an extra 32 test strips as an added bonus. It helps get you in the ballpark with your water perimeters. I mean some people would never do a water test at all. Tank lids, water additives and more have seen the same effect.

"Best strips ever."Accurate results and much much cheaper than buying from a pet chain. Always nice to get something extra! To test it, I bought a 5 pack of 5 site test strips from Petco. Before, I brought water into a pet store, but kept seeing no signs of improvement. But it is accurate and convenient as is. I have a freshwater tank that includes some delicate invertebrates. The nitrate test is a little finicky as most users will agree.

All bottles clearly labeled and tell you how many drops. And if it was, please click on the helpful button below. First few strips I used gave an accurate ready. I get a consistent reading every time, retests included. Not really sure if there is a way to fix that though.

"Strips work great!"No one brand is going to guarantee against this. If you keep freshwater fish, you will need this test kit. Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. Besides these few flaws I have to say it's a great starter kit. These are working very well for me. I found running all the tests took me around 10 minutes. They showed the same results as these for the sites they had in common.

"These strips are great."Nice that so many things are tested with one dip in the water. If your lighting isn't right the colors will be very off. I have not had any problem whatsoever. I take every precaution about the chlorine, and trust the strips for everything else. It's quick and easy and can give you an alert if something may be going on. But just for a quick check, its hard to beat these test strips. It you take it to a local fish store.

It does'not' have the same accuracy but it’s very close. My tap water actually was really green and was a very close match to the 1. Unfortunately nitrates still might be the most important test, at least for me it is. This is a kit to test for my aquarium water quality.

But it is accurate and convenient as is. I'm still not sure about the chlorine site. The API Test Strips are a good water monitoring system for small tanks.

"75, for example."They're super easy to read and seem to be pretty accurate. It looks to have the slightest green tinge but is not as green as the 0. If you're out for speed, but with less accuracy get the dip tests. I find that the accuracy is wrong in the sense it's better than it reads. This test kit is easy to use and the results are easy to read. The caps do leak a tiny bit on the tubes. Probably won't buy again because of the bleeding issues.

"00 becomes 40."Will definitely buy again, if we ever run out! This is a kit to test for my aquarium water quality. Tank lids, water additives and more have seen the same effect. It does take some time though to actually get it done. Dip it in the water horizontally and keep it horizontal and read it against bottle. I'm still not sure about the chlorine site. I set up a bunch of 20 gallon tanks for fry and stuff.

It helps get you in the ballpark with your water perimeters. My results are never all over the place like other reviewers. As you can see in comparison the only difference was the Nitrate. I get a consistent reading every time, retests included.
