Review on 🐠 Efficiently Oxygenate Aquariums and Hydroponic Systems with PONDFORSE Air Pump: Adjustable Flow Control, 475GPH Power, 20W 30L/min by Jocelyn Hernandez

The volume of this vent is about the same as my old fridge. Talking to him is easy enough, but you know exactly when it's not working. That being said, I tried making it low to let some bubbles come out of the reservoir. It doesn't like being low and turns on and off without being touched. The regulator needs to be at least halfway down for this air pump to stay on reliably. I solved this problem by using a flow regulator and running the pump at half power (which is louder than low power). I'll probably get another brand/pump if this one dies.
