I had planned on placing this on a shelf of the aquarium stand which of course is below the tank. If I'm using a check valve do I really need to have this above the tank? I would really hate to hang a shelf on the wall just to set the air pump, it would really look out of place in my living room. Any thoughts?
You will need a check valve to stop the back flow due to siphoning action in case of power outage if you cannot place the pump above the water level of the tank.
I found this one from Petco really good because it has a built-in check valve, and 2 valves for 2 items, with
a control valve to control the strength of the air. I have one and I love it, it is cheaper than getting all the parts to accomplish air flow control and back flow control.
The check valve is at the bottom, the black knobs are the control valves.
