2 of my jebao pumps went out within the last month or so. I've been running them on the jebao to apex module. If I put my finger on the prop, I can kinda feel like the pump wants to spin. Sometimes i can get it to spin when it's out of water, but as soon as I put them in the water they quit. So my question is, if maybe the power supplies are bad. I'm supposed to run the apex to jebao module on a stronger power supply. Anyone have experience or an amazon link as to which power supply I should be getting? This is the one from fish street, but I'd like to order from amazon prime.
