DreadedHermie Reviewed by DreadedHermie on . DWC Pump Problems Ok so I have 8 rubbermaids (2 gal or so) with 1 plant in each. I have 4 duel outlet pumps I picked up at walmart however the airline hose to some is fairly long and barely any bubbles come out after a few days of running. They say the output is 2.5 psi. I am aware that shorter hose length is a possible solution but I don't really have the option of haivng the pumps inside the area due to having nowhere to elevate them over the water level and no power source to plug em. So I guess my Rating: 5
