Easy To Use, Works Great!
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.

Procedures are easy to follow
Canât really tell if this is accurate since I have nothing to compare it with. However, itâs 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, Iâd be more satisfied if the cost was slightly lower. But, itâs a cheaper alternative to a DO meter.

Very helpful test
Needed this test to see if one of our pet axolotls was low on oxygen in his tank and everything else was fine luckily it helped us figure out his oxygen levels and heâs been fine ever since

Kit works but arrived damaged
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.

Easy to use and accurate
I bought this for my science fair project on marine sciences and itâs 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 itâs really simple.

Now i know
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.
