"Great test kit."

Tank lids, water additives and more have seen the same effect. It's quick and easy and can give you an alert if something may be going on. I find that the accuracy is wrong in the sense it's better than it reads. Just be careful, after all these are chemicals. The nitrate test is a little finicky as most users will agree. Takes about 5 minutes to check everything. My tap water actually was really green and was a very close match to the 1.

Nutrafin A7860 Final Thoughts

"It's worth it."

If you're out for speed, but with less accuracy get the dip tests. I used to always take a water sample to the pet store and they would teat it. This spreads out the 6 month expiration date after opening. A plus is that they don't bleed colors while testing. It does'not' have the same accuracy but it’s very close. Comes with a lot of test strips, that are extremely easy to use and read. Unfortunately nitrates still might be the most important test, at least for me it is.

Nutrafin A7845 First Impressions

"A great kit!"

If you keep freshwater fish, you will need this test kit. 6 and run a high pH you will see it could actually be 7. It was also kinda hard to get exactly 5ml Into the tubes. It's difficult to tell if all the test sites on the strip are accurate. I tested the water and the nitrates and the ph were pretty high still. Not really sure if there is a way to fix that though. This is essential for an accurate reading.

Nutrafin A7845 Final Thoughts

"5 out of 5 stars."

I would not use it solely for checking nitrate and nitrites. The key is that you are looking for changes. All bottles clearly labeled and tell you how many drops. It does take some time though to actually get it done. I used to always take a water sample to the pet store and they would teat it. Before, I brought water into a pet store, but kept seeing no signs of improvement. I take every precaution about the chlorine, and trust the strips for everything else.

"Like nuclear waste water."

It shows it could be between 1-20 but the liquid shows 0. They showed the same results as these for the sites they had in common. The nitrate test is a little finicky as most users will agree. I have not had any problem whatsoever. The test strips work as advertised. I tested the water and the nitrates and the ph were pretty high still. This is essential for an accurate reading.

"Used the same kit before."

I found running all the tests took me around 10 minutes. These have worked to keep my fish safe and healthy. The API Test Strips are a good water monitoring system for small tanks. In my opinion they arent quite as accurate as master test kits either. Will definitely buy again, if we ever run out! Overall good value for a small hobbyist aquarium owner. But if it's wrong at least I was proactive about it.

If your lighting isn't right the colors will be very off. As you can see in comparison the only difference was the Nitrate. If your lighting isn't right the colors will be very off.

Nutrafin A7855 Final Thoughts

"I disagree."

Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. You mostly find them using API also. I set up a bunch of 20 gallon tanks for fry and stuff. You mostly find them using API also. A plus is that they don't bleed colors while testing. No one brand is going to guarantee against this. This test kit is easy to use and the results are easy to read.

"Helps keep my fish happy."

Not really sure if there is a way to fix that though. Strips are accurate as far as I can tell. Very helpful for checking the water in our tank. Always nice to get something extra! I wouldn't call this a master kit but a great start. Probably won't buy again because of the bleeding issues. If I had a complaint, I wish the color legend was printed on the bottle.
