"This part is very easy."

I take every precaution about the chlorine, and trust the strips for everything else. Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. No one brand is going to guarantee against this. I find that the accuracy is wrong in the sense it's better than it reads. But just for a quick check, its hard to beat these test strips. Not really sure if there is a way to fix that though. 6 and run a high pH you will see it could actually be 7.

Aquarium Equip PTM691I506 Final Thoughts

"Super easy to use."

Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. I have a freshwater tank that includes some delicate invertebrates. This is no different so I wouldn't knock this product for that. This is not the right way to use this test, as it took me awhile to realize this. Will definitely buy again, if we ever run out! The stripa are easy to use, clear instructions and I gor results in seconds. Here's Tetra's strips if you're curious.

"Just sayin'."

These strips are not to be trusted as a primary testing method for aquariums. 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. If you're out for speed, but with less accuracy get the dip tests. I'm still not sure about the chlorine site. It's really accurate and makes me feel like I'm a scientist while doing it. You never want to wait too long and the tank crashes and has major problems.

"Simple and easy to use."

I will now test my water periodically to make sure everything is ok. If you keep freshwater fish, you will need this test kit. Will definitely buy again, if we ever run out! This kit is extremely accurate and very well designed for convenient use and storage. My tap water actually was really green and was a very close match to the 1. Wasn't labeled that way in the descriptor. I even got an extra 32 test strips as an added bonus.

Hanna Instruments HI 758 First Impressions

"Thank you."

This is essential for an accurate reading. Some of the readings develop better than others. In my opinion they arent quite as accurate as master test kits either. These strips are not to be trusted as a primary testing method for aquariums. A plus is that they don't bleed colors while testing. It's really accurate and makes me feel like I'm a scientist while doing it. It was also kinda hard to get exactly 5ml Into the tubes.

Hanna Instruments HI 758 Final Thoughts

"Using this meter is easy."

So did another water change today and now I have happy fish. The test strips work as advertised. I get a consistent reading every time, retests included. It shows it could be between 1-20 but the liquid shows 0. You mostly find them using API also. Besides these few flaws I have to say it's a great starter kit. I like API products and find them the most accurate.

"They work for me."

The strips are able to monitor pH, nitrate, nitrite, water hardness. 6 and run a high pH you will see it could actually be 7. I wouldn't call this a master kit but a great start. Some of the readings develop better than others. But just for a quick check, its hard to beat these test strips. Definitely recommend this test strip for anyone who has a Betta fish as a pet. Quantity of strips seems very good.

"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.

"Perfect for quick checks."

These helped me check the levels and they were easy to use. To test it, I bought a 5 pack of 5 site test strips from Petco. The caps do leak a tiny bit on the tubes.

"However, it is not."

Tetra has always done that and I will continue to use their products. All bottles clearly labeled and tell you how many drops. But it turns out that is not the case. Before, I brought water into a pet store, but kept seeing no signs of improvement. I like API products and find them the most accurate. This is a good kit so much more accurate and easy to figure out how to use it. These helped me check the levels and they were easy to use.

"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.

Sera 4310 Final Thoughts

"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.

If you're looking for a quick-hit on a range of water quality these are the answer. If this review was helpful, please click the helpful button! Well I found out why they were gulping so bad. While using these weirder chemicals, it worries me a little bit. You mostly find them using API also. To test it, I bought a 5 pack of 5 site test strips from Petco.

"I disagree."

Having the key on the bottle is very helpful, it won't get lost. If you want accurate pH get the API liquid test that includes pH and high pH. This test kit is easy to use and the results are easy to read. I've already lost one test tube cap, most likely due to my cats playing with them.

It helps get you in the ballpark with your water perimeters. This spreads out the 6 month expiration date after opening.

"That is time consuming."

The caps do leak a tiny bit on the tubes. This is a good kit so much more accurate and easy to figure out how to use it. They showed the same results as these for the sites they had in common. I'm still not sure about the chlorine site. I would not use it solely for checking nitrate and nitrites. They test pretty accurate when run against my chemical tests. First and second test have a little change which was expected.

This spreads out the 6 month expiration date after opening. They show results, what is safe& not safe and what to do if not safe. I find that the accuracy is wrong in the sense it's better than it reads. I'm the test strip came in handy it saved all of my fish. It does'not' have the same accuracy but it’s very close. These helped me check the levels and they were easy to use. Very helpful for checking the water in our tank.
