Review 1 for Petco 2-Way Air Control & Check Valve Combo for Fresh & Saltwater Aquariums
One way control
PostedSeptember 3, 2012
I love that this item come with a built in check valve. The controls are easy to use. The whole thing can be hung on the side of a tank for easy access. When running the valve full open with a tetra whisper 20 pump the check valve hums a little but i can't hear it unless my filter system is off.
