Review on 🐠 LAWNFUL Aquarium Air Pump: Ultra Quiet 4 Outlet Fish Tank Pump with Adjustable Air Valve - Ideal for Hydroponics, Ponds, and Aquariums by Julie Watkins

advantages of this pump; Super quiet I have it in my bedroom and not annoying at all. Can launch multiple tanks at once. Excellent value for money and quality. minuses; I currently have 4 small sponge filters and one large. The downside is that if you try to run 2 filters in the same tank on the same line, it will be pulled away from the other filters. I also hooked up 3 small sponge filters and a decorative bubbler and it didn't force air through the decorative bubbler until it hopped to the sponge filters. Apart from that, you can't beat the price for it. I am in the process of opening up my aquarium space and am looking at 16 x 55 gallon aquariums. I will try this pump on 2 tanks and 4 large filters and see if it keeps up with the tanks.
