Things were flowing along great. This morning I noticed that the water level dropped and lost the siphon on the filter. I topped it off and got the siphon going, and noticed the powerhead was not pumping water back into the tank. The sump overflowed. I took the powerhead pump out of the water and it was running. When I put it back into the water it would pump water for about 2 seconds, then quit. I had to turn the whole thing off before leaving for work. I know NOTHING about these wet/dry sumps. Any help is appreciated. My bulldog can't swim.
