"Maybe I have bad bottle."

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. But if it's wrong at least I was proactive about it.

"00 becomes 40."

Every test I do takes just a few drops. Overall, I am very happy with this kit. This kit is extremely accurate and very well designed for convenient use and storage. 6 showing the test strip as an accurate reading. First and second test have a little change which was expected. Their Whisper 1-5 filter cartridges have skyrocketed in price and become a scarcity. Very good instructions and a comparison color chart.

"These are great!"

It's really accurate and makes me feel like I'm a scientist while doing it. If you keep freshwater fish, you will need this test kit. But if it's wrong at least I was proactive about it.

"Two packages were inside."

This is essential for an accurate reading. No one brand is going to guarantee against this. A brand new aquarium will experience what is called a cycle. Strips were always stored in a sealed dry place. I have a 55 gallon tank with a few large goldfish. Some of the readings develop better than others. I have not found that to be true for myself.

"Would buy again for sure!"

But after last night these are a must have for me. 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. Not really sure if there is a way to fix that though. It does'not' have the same accuracy but it’s very close. I would not use it solely for checking nitrate and nitrites. The rest of the test in the kit are much easier to use.

"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.

"They work for me."

These strips are not to be trusted as a primary testing method for aquariums. The price is great for all these essential tests! I have not found that to be true for myself. It is one small part of the overall aquarium ownership experience. The nitrate test is a little finicky as most users will agree. The strips are able to monitor pH, nitrate, nitrite, water hardness. Having the key on the bottle is very helpful, it won't get lost.

"It's that easy."

Not sure if the reading is 0 or more likely something between 0-. My 12 yrs old son wanted a fish tank so we got him 2. The nitrate test is a little finicky as most users will agree. To test it, I bought a 5 pack of 5 site test strips from Petco. But it turns out that is not the case. I wouldn't call this a master kit but a great start. Very helpful for checking the water in our tank.

"Hope this was useful."

But, I will continue to order Tetra's 6 in 1 until someone makes a better test strip. I used to always take a water sample to the pet store and they would teat it. The API Test Strips are a good water monitoring system for small tanks. A brand new aquarium will experience what is called a cycle. I have a freshwater tank that includes some delicate invertebrates. Best price, best quality, fair accuracy and better than most brands, etc. Best price, best quality, fair accuracy and better than most brands, etc.
