I bought a jebao 404 canister filter. been running it and pretty happy with it for the price. does anybody know how to disconnect the in/ out hoses. there is a button on each hose that releases the hose but I can't stop the water from flowing out. yes, I did unplug it. I also turned the flow valve all the way down, but water keeps coming out. you would think that just disconnecting it would cut off the water. instructions were in Chinese and I trashed it.
