I have a 7,200 gallon koi pond in my backyard that is has a biofilter and pump that cycles the water out at one end where the skimmer is, and over a waterfall for aeration and back into the pond at the other end. Today I went out to discover that the waterfall had no water running over it. I know there is still power going to it because the UV filter light is on and I can still feel vibrations near the intake. Also, there is some water being pulled in. Do you think there is a clog somewhere in the line or could the pump be having problems? The fish seem ok right now but I don't know how long they will survive without the waterfall running? Any advice is appreciated!
