Monitor DISSOLVED Oxygen Test KIT (50 Tests) - Monitor Aquarium and aquaculture Water Quality

This kit is so easy to use. Honestly, I thought it was gonna be really confusing from looking at it, but one walk through and I haven't had to look at the directions again. It really helped me realize I didn't have enough flow in one of my aquariums and since using this test kit, and making some adjustments, my fish are all out and about more than they were.

The media could not be loaded. I bought this for my science fair project on marine sciences and it’s surprisingly easy and fun to use! So accurate and makes for a great tool. Along with that, I feel so professional and fancy like a certified scientist while using it. I just put a brief instructional video in here because the instructions make this seem difficult, but it’s really simple.

Great kit to verify your aquarium is properly oxygenated.

I use this to test my aquarium water and it was really easy to use and had some awesome water bottles that were reusable with corked tops! So amazing, really easy to use and the instructions were easy to follow as well.

Precision is questionable.

these are good quality testing kit. doesn't take long to use, worth the money.

I have used multiple times and get the same readings when I should not. I don't think it is accurate or the instructions or chemicals are wrong. I teach science and used for labs. Could not get readings to differentiate extreme hot vs cold water. Hot (212 degrees) should have much less oxygen.

Worked as it should to determine oxygen content in our pond Nice tool to have on hand
