"Was good for 3 years."

This is no different so I wouldn't knock this product for that. These strips are not to be trusted as a primary testing method for aquariums. If your lighting isn't right the colors will be very off. The rest of the test in the kit are much easier to use. The strips are able to monitor pH, nitrate, nitrite, water hardness. My 12 yrs old son wanted a fish tank so we got him 2. Comes with a lot of test strips, that are extremely easy to use and read.

"Hope this was useful."

I started wearing gloves when I use the kit. I started wearing gloves when I use the kit. It's quick and easy and can give you an alert if something may be going on. They show results, what is safe& not safe and what to do if not safe. It's difficult to tell if all the test sites on the strip are accurate. Dip it in the water horizontally and keep it horizontal and read it against bottle. I respect a company that backs their product.

"Exactly as pictured."

I mean some people would never do a water test at all. Before, I brought water into a pet store, but kept seeing no signs of improvement. I have some pretty lousy water where I live. It's quick and easy and can give you an alert if something may be going on. This is a kit to test for my aquarium water quality. 6 and run a high pH you will see it could actually be 7. While using these weirder chemicals, it worries me a little bit.

"Worked great."

Very good instructions and a comparison color chart. I used to always take a water sample to the pet store and they would teat it. The key is that you are looking for changes. So this thing worked very well and gave a reading that made perfect sense. I was having trouble keeping my fish tank water looking good. They showed the same results as these for the sites they had in common. First few strips I used gave an accurate ready.

"Worth the money."

It helps get you in the ballpark with your water perimeters. It looks to have the slightest green tinge but is not as green as the 0. It's really accurate and makes me feel like I'm a scientist while doing it. This spreads out the 6 month expiration date after opening. Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. To test it, I bought a 5 pack of 5 site test strips from Petco. Some of the readings develop better than others.

"Also they leak."

These helped me check the levels and they were easy to use. I was having trouble keeping my fish tank water looking good. The test strips work as advertised. It does take some time though to actually get it done. Overall good value for a small hobbyist aquarium owner. The stripa are easy to use, clear instructions and I gor results in seconds. I wish there were a simpler accurate test for it.

"They work for me."

They're super easy to read and seem to be pretty accurate. I wish there were a simpler accurate test for it. Nice that so many things are tested with one dip in the water. Price is good for the quantity and functionality of the tester strips. As you can see in comparison the only difference was the Nitrate. Besides these few flaws I have to say it's a great starter kit. Unfortunately nitrates still might be the most important test, at least for me it is.

"I don't know."

This kit is extremely accurate and very well designed for convenient use and storage. It is easy to use and accurate enough. Then replace the caps of the bottle and test vial. No issues so far, test strips work well. Just dip the strip in the tank water for two seconds, then read right away. But it is accurate and convenient as is. Not really sure if there is a way to fix that though.

"So they're measuring!"

It does not test ammonia but that's clear in the description and bottle. This is not the right way to use this test, as it took me awhile to realize this. Tetra has always done that and I will continue to use their products. All bottles clearly labeled and tell you how many drops. My 12 yrs old son wanted a fish tank so we got him 2. They quickly shipped me a new product. Strips are accurate as far as I can tell.

"This part is very easy."

They showed the same results as these for the sites they had in common. I would not use it solely for checking nitrate and nitrites. I respect a company that backs their product. A brand new aquarium will experience what is called a cycle. I've already lost one test tube cap, most likely due to my cats playing with them. These are working very well for me. Always nice to get something extra!

"Easy to read."

So off to buy some sponge filters I went! I would not use it solely for checking nitrate and nitrites. If your lighting isn't right the colors will be very off. My tap water actually was really green and was a very close match to the 1. Well I found out why they were gulping so bad. This spreads out the 6 month expiration date after opening.

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.

"However, it is not."

This test kit is easy to use and the results are easy to read. I respect a company that backs their product. It's really accurate and makes me feel like I'm a scientist while doing it. I find that the accuracy is wrong in the sense it's better than it reads. Very good instructions and a comparison color chart. Just dip the strip in the tank water for two seconds, then read right away. Not really sure if there is a way to fix that though.

"I know, I'm terrible."

The price is great for all these essential tests! It's difficult to tell if all the test sites on the strip are accurate. It you take it to a local fish store. Unfortunately nitrates still might be the most important test, at least for me it is. It does'not' have the same accuracy but it’s very close. Tank lids, water additives and more have seen the same effect. I find that the accuracy is wrong in the sense it's better than it reads.

I will now test my water periodically to make sure everything is ok. These are do helpful with maintaining your tank. It does not test ammonia but that's clear in the description and bottle. This kit is extremely accurate and very well designed for convenient use and storage. These strips work very well and I have had consistent results with them. Also, I'd avoid Tetra's strips to be honest- the reviews speak for themselves. My water was good to go and soon after I for fish that are doing well!
