BIONIX Dissolve Oxygen Test Kit (100 Test)

For such an affordable price, the Bionix Dissolved Oxygen kit is an absolute steal. It is a straightforward kit, but don’t let the low cost fool you—it works perfectly. The reagents and instructions are clear, the colour change is easy to read, and it delivers consistently accurate results every time. It proves you don’t need expensive digital gear to monitor your aquatic health properly. If you want a budget-friendly kit that just works, Bionix is the way to go. Highly recommended.

I purchased it for the pond because fish need oxygen to survive. I'm happy it works well because it would be very useful in the winter and cloudy months.

Value for money

Perfect test kit for accurate results. Everything needed including the instruction manual comes in the pack. Tried it in 2 of my tanks and it gave accurate results for dissolved oxygen. Value for money product
