Monitor DISSOLVED Oxygen Test KIT (60 Tests) - Monitor Aquarium and aquaculture Water Quality

Works very well, and price is great compared to other dissolved oxygen testers.

Great option for something super important yet hard to find test kits for for some reason. I usually use the Salifert brand but it has been out of stock everywhere.

This is a very nice O2 test kit. Easy to use. Works well. Highly recommend.

This is super easy and extremely helpful taking care of our little pond. I'm sure this is much less expensive than other options too

Is easy to use , I am just wondering on the accuracy of the results. Has anybody tested the results to a quality oxygen meter? I'm just hoping its accurate

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.

We used the test kit today in my AP Environmental Science class and it worked as far as we can tell. The video provided was very helpful. The only issue is that one of the reagent bottles leaked in the box and there's not much left in it now.

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.
