Review on 🧪 Dissolved Oxygen TesTab Refill by LaMotte: Optimize Your Testing Efforts by Jeff Kersey

This replacement product works quickly and easily with the original dissolved oxygen kit for your local pond. All you have to do is follow the instructions with the original kit. If you run out of test pills in the original set you don't need to buy a whole new set - just a stock of test pills - great concept and design
