Review on 🐠 Jebao Doser 2.4 WiFi 4-Channel Auto Dosing Pump - Dark Grey | Enhance your Saltwater Reef Aquarium by Stephanie Graves

Will not withstand constant fluid pressure. Even after all air bubbles are removed, a large amount of gas remains in the tube the next day. I use tight hose clamps and the right size silicone metering tubing, but that just doesn't keep it in place all the time. As a result, only air escapes during dosing. Very frustrating. I would not buy. Pay a little more and get a decent dispenser. My return period has expired, otherwise I would have sent it back.
