Review on 🐠 HITOP Single Outlet Aquarium Air Pump: Quiet Oxygen Pump with Accessories for Small Tanks up to 15 Gallons by Holly Hunter

The pump is producing much more air than I need for a very small volume application. I'm sure he has enough beans for a decent aquarium. One star deduction because the accessories are usually terrible. The tube is creepy - and it will turn yellow within a week if exposed to anything. Slightly yellowed at the pump where hot air comes out. and it turned yellow where it was in the liquid. It's also so soft that it's difficult to access the ports (which it's too small for). I will most likely replace it. The air stone is fine. The bypass valve is very thin. Overall a pretty good package for the price.
