Review on 🐠 COMOK 4-Way Aquarium Air Control Valve with Flow Switch by Paula Pickett

A few days later I received a 4-way air valve. I like clear plastic because it's a lot less obtrusive than green or black. I also like that the hose to the pump is at the bottom. This allows the hose to hang straight down and not to the sides. It looks better and takes up less space. The only thing I would like to change is that it had two inlet hose mounts instead of just one.
