Review on 💨 Cobalt Aquatics Emergency Air Pump: Ensuring Optimal Oxygen Levels in Critical Situations by Teresa Quinney

I've been using it for a month now and there is half an inch of foam sitting behind the show tank. The unit is louder than anything related to my reef tank including the protein skimmer when it oozes out. I can even hear it clearly competing with the waterfall between my two tanks. It's even louder than the reliably working AC air pump it replaces at the national retailer. That being said, I checked the power outage and the unit is still pumping air. I am currently testing how long the battery lasts and will update the test report with the result. Two other little things I don't like are the constantly flashing LEDs, which are connected to an outlet with a backup power supply. The power cord is really short. All in all at the moment I don't think you will find better functionality.
