when I was feeding the fish… around 10:30 am, their usual time, lol… I discovered that one of the pumps was running, but the water wasn’t…
I turned it off, removed it, and put the pieces into the sink… after cleaning everything, it still didn’t work…

I placed the filter on the front of the tank so I could fiddle with the little impeller and was thrilled when it started working…
we can’t get to the fish store until next week to replace this pump… the fish will be fine until then, even though the tank looks odd and it is hard to see them, lol…
