"00 becomes 40."

The rest of the test in the kit are much easier to use. Overall, I am very happy with this kit. 32 seconds and I have a reading and I'm on my way with no mess. Best price, best quality, fair accuracy and better than most brands, etc. I have a freshwater tank that includes some delicate invertebrates. Easy to use, a good quantity and quality for the price. Not sure if the reading is 0 or more likely something between 0-.

Milliard MIL-AQM-A First Impressions

"A great kit!"

I have a 55 gallon tank with a few large goldfish. It is easy to use and accurate enough. This is a good kit so much more accurate and easy to figure out how to use it. Then replace the caps of the bottle and test vial. Besides these few flaws I have to say it's a great starter kit. I find that the accuracy is wrong in the sense it's better than it reads. No issues so far, test strips work well.

Salifert First Impressions

"Two packages were inside."

It is easy to use and accurate enough. A brand new aquarium will experience what is called a cycle. Not sure if the reading is 0 or more likely something between 0-. I will now test my water periodically to make sure everything is ok. It does take some time though to actually get it done. Just dip the strip in the tank water for two seconds, then read right away. I'm still not sure about the chlorine site.

"These strips are great."

But it turns out that is not the case. Takes about 5 minutes to check everything. The stripa are easy to use, clear instructions and I gor results in seconds. Having the key on the bottle is very helpful, it won't get lost. If you keep freshwater fish, you will need this test kit. The API Test Strips are a good water monitoring system for small tanks. I take every precaution about the chlorine, and trust the strips for everything else.

NYOS First Impressions

"FIVE STARS for sure!"

It you take it to a local fish store. Every test I do takes just a few drops. They showed the same results as these for the sites they had in common. Well I found out why they were gulping so bad. This is not the right way to use this test, as it took me awhile to realize this. These helped me check the levels and they were easy to use. Definitely recommend this test strip for anyone who has a Betta fish as a pet.

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.

"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.

", is that a 6, 6."

The test strips work as advertised. These helped me check the levels and they were easy to use. Wasn't labeled that way in the descriptor. Overall, I am very happy with this kit. It was also kinda hard to get exactly 5ml Into the tubes. This spreads out the 6 month expiration date after opening. The kH pad sometimes has the same problem as well.

So off to buy some sponge filters I went! I take every precaution about the chlorine, and trust the strips for everything else. Strips were always stored in a sealed dry place. This test kit is easy to use and the results are easy to read. They quickly shipped me a new product. But it is accurate and convenient as is. Tank lids, water additives and more have seen the same effect.
