Review on 🐠 KEDSUM Aquarium Air Pump: Silent Operation with 4 Air Outlets/Stones/Tubes/Check Valves for 25-180Gallon Fish Tanks by Eric Teofilo

Underpowered for its size. The thing is huge! And the two air valves on the left are much stronger than the two on the right! It is totally unbalanced and underpowered for its size. I have small Tetra whisper pumps that are much more powerful and just as quiet, but cost a lot less! I sent a message to the seller and received no reply! ! ! I buy a lot of aquarium products because I am a tropical fish breeder. I will not buy from a seller who sells defective products and then ignores messages from their buyers.
