Review on 🐠 UPETTOOLS Aquarium Air Pump: High-Performance Oxygen Pump for Deepwater Fish Tanks with Adjustable Aerator and 2 Outlets by Melissa Davis

I've had him for about a month now and I think he needs a break. It seems to deliver more air than when it was first installed. I use a double sponge filter and a 30" LED bubble wand in an 18" tank. First I had to increase the pump power to about 3/4 power to get the bubble stick bubbling enough, now it runs on the lowest level which is very quiet. i hear bubbles no pump. At the highest level I hear the pump. I hope it lasts long. I recommend this pump if you need more power than the main pump.
