Review on 🐠 AQQA Aquarium Air Pump, 2 Air Outlets Oxygen Bubbles Pump - High Energy Saving Adjustable Air Flow Ultra-Quiet Pump, for Fish Tank Up to 300/600 Gallons by Michelle Ocampo

I bought this to replace a very old dual port Rema Air 400. Pros: Looks good. Continuous. Looks well built. SOME adjustable. Cons: (1) Not as "super quiet" as advertised. Possibly quieter than a cheap pet store pump, even when placed on a foam pad. Connected to both ports and low noise, still more than my old Rema Air 400! - one star, (2) I have a timer. When the power is turned off with a timer, it defaults to a "high" setting compared to the low setting I wanted it to stay on - one star. (3) only has 3 or 4 airflow settings. I prefer a dial plan that I can customize to my needs, so I go back and put my old Rema Air 400 back on.
