"Best strips ever."

Very helpful for checking the water in our tank. It does take some time though to actually get it done. So I got these to try and I love them. Unfortunately nitrates still might be the most important test, at least for me it is. Very helpful for checking the water in our tank. They showed the same results as these for the sites they had in common. This is essential for an accurate reading.

Sera 4960 Final Thoughts

"However, it is not."

Then put the cap on the test vial and invert it several times. The kH pad sometimes has the same problem as well. I take every precaution about the chlorine, and trust the strips for everything else. I started wearing gloves when I use the kit. These strips are not to be trusted as a primary testing method for aquariums. I have some pretty lousy water where I live. This kit is extremely accurate and very well designed for convenient use and storage.

"Worked pretty well."

These are do helpful with maintaining your tank. They test pretty accurate when run against my chemical tests. While using these weirder chemicals, it worries me a little bit. 6 and run a high pH you will see it could actually be 7. The stripa are easy to use, clear instructions and I gor results in seconds.

"Will purchase again!"

A brand new aquarium will experience what is called a cycle. Some of the readings develop better than others. I wish there were a simpler accurate test for it. I respect a company that backs their product. These have worked to keep my fish safe and healthy. To test it, I bought a 5 pack of 5 site test strips from Petco. Always nice to get something extra!

"That is time consuming."

The test strips work as advertised. They show results, what is safe& not safe and what to do if not safe. But after last night these are a must have for me. I was having trouble keeping my fish tank water looking good. I take every precaution about the chlorine, and trust the strips for everything else. About my pic color difference of the water and the chart and about the bad reviews. They show results, what is safe& not safe and what to do if not safe.

"I love this test kit."

Probably won't buy again because of the bleeding issues. These helped me check the levels and they were easy to use. It does not test ammonia but that's clear in the description and bottle. I even got an extra 32 test strips as an added bonus. Nice that so many things are tested with one dip in the water. Nice to have in hand when you own an aquarium. So did another water change today and now I have happy fish.

"These are just easier."

If you're out for speed, but with less accuracy get the dip tests. I have not had any problem whatsoever. This is essential for an accurate reading. I mean some people would never do a water test at all. 6 and run a high pH you will see it could actually be 7. It looks to have the slightest green tinge but is not as green as the 0. So I got these to try and I love them.

Tetra has always done that and I will continue to use their products. This kit is extremely accurate and very well designed for convenient use and storage. It is one small part of the overall aquarium ownership experience. This is no different so I wouldn't knock this product for that. It you take it to a local fish store.

"Easy to use."

As you can see in comparison the only difference was the Nitrate. A brand new aquarium will experience what is called a cycle. No issues so far, test strips work well. Here's Tetra's strips if you're curious. These have worked to keep my fish safe and healthy. My tap water actually was really green and was a very close match to the 1. I started wearing gloves when I use the kit.

"I used API prior to this."

It does not test ammonia but that's clear in the description and bottle. I tested the water and the nitrates and the ph were pretty high still. I've already lost one test tube cap, most likely due to my cats playing with them. I have not had any problem whatsoever. I set up a bunch of 20 gallon tanks for fry and stuff. It shows it could be between 1-20 but the liquid shows 0. If you keep freshwater fish, you will need this test kit.

"Helps keep my fish happy."

They quickly shipped me a new product. Very helpful for checking the water in our tank. My tap water actually was really green and was a very close match to the 1. Definitely recommend this test strip for anyone who has a Betta fish as a pet. Overall good value for a small hobbyist aquarium owner.

"Thank you!"

This is essential for an accurate reading. This is not the right way to use this test, as it took me awhile to realize this. Definitely recommend this test strip for anyone who has a Betta fish as a pet. It does'not' have the same accuracy but it’s very close. The test strips work as advertised. The price is great for all these essential tests! My water was good to go and soon after I for fish that are doing well!

Overall good value for a small hobbyist aquarium owner. I have a freshwater tank that includes some delicate invertebrates. Very easy to use and very easy to read test strips.

I like API products and find them the most accurate. This test kit is easy to use and the results are easy to read. While using these weirder chemicals, it worries me a little bit.

"FIVE STARS for sure!"

If your lighting isn't right the colors will be very off. I would not use it solely for checking nitrate and nitrites. The nitrate test is a little finicky as most users will agree. My tap water actually was really green and was a very close match to the 1. I find that the accuracy is wrong in the sense it's better than it reads. It was also kinda hard to get exactly 5ml Into the tubes. But after last night these are a must have for me.

"This part is very easy."

I find that the accuracy is wrong in the sense it's better than it reads. The key is that you are looking for changes. They show results, what is safe& not safe and what to do if not safe. My 12 yrs old son wanted a fish tank so we got him 2. 6 showing the test strip as an accurate reading. I have not had any problem whatsoever. If you keep freshwater fish, you will need this test kit.

"These strips are great."

Wasn't labeled that way in the descriptor. Strips were always stored in a sealed dry place. As you can see in comparison the only difference was the Nitrate. Not really sure if there is a way to fix that though. I set up a bunch of 20 gallon tanks for fry and stuff. Not sure if the reading is 0 or more likely something between 0-. 6 and run a high pH you will see it could actually be 7.
