Salifert Dissolved Oxygen Test Kit

Easy to use, seems very accurate

I used this to test the oxygen in an aquarium that had an unexpected fish death. I thought the oxygen was probably OK based on the filtration I was using, and this test confirmed that it was fine. It was only a little more complicated than other liquid aquarium test kits, so if you've done the nitrate test with the multiple chemicals where you have to shake the bottles and wait 1 minute here and 5 minutes there, this should be easy for you. It was a LOT easier to read than other kits I've used for water testing, probably because this one comes with a little cup instead of the skinny tube that comes in most kits. I was skeptical based on some of the reviews, but after using it I have nothing negative to say and I would definitely recommend it.

Takes longer than your normal tests. But works well

easy to use and has worked every time except the first time I tried to use it, the water stayed clear, so I think I did something wrong. Is giving me pretty consistent readings on 3 different tanks for a week, so I'm happy with this purchase. Even though I thought the price was too high, it's worth it to know, especially since I did end up needing to add more oxygen to one of my tanks.

I recommend this product highly. I have a farm pond and this product works great for testing O2 levels. I had no problems with deliver and product was exactly as described.

I think that even with the several steps required it is easy to use. The results, however, are hard to read because (like another reviewer said) the color I get doesn’t match any of the colors on the chart. It’s sort of a guess. I’m pretty disappointed especially considering the price. I wouldn’t purchase it again.

Since the clear plastic test vial used for comparing the treated sample with the color chart was unusable due to it being broken, theres no way to know!

I really can't say how accurate this is, since I have no other way of testing the oxygen level in the water. It only took a few minutes to complete the test and the instructions were clear.
