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

exactly as described, works well

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

Can’t really tell if this is accurate since I have nothing to compare it with. However, it’s pretty simple to use. The procedures are easy to follow. Just hoping for the results to be accurate. I used it to monitor my fish tank DO. A little expensive, I’d be more satisfied if the cost was slightly lower. But, it’s a cheaper alternative to a DO meter.

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.

Glad i bought this. I was always wondering if i had enough oxygen in my aquarium for my fish, and now with this kit i know. Directions are easy to read and follow. No color chart to match to like the API tests so i feel its more accurate.

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.
