I have a river tank by Finn Strong. It was working just great the other day, but I had to change the filter and now it's not pumping water up, so the water's not flowing into the other sections of the tank...any idea what I need to do to get it working again?
I have the "Large" version of the same rivertank kit. The pump does not normally come with the kit (I use a Maxi-Jet 1200). You should be able to take the pump that you have out and clean and test it, it may need to be replaced. It is a good idea to have a backup in hand so if possible buy 2 if you end up getting a replacement.
To remove the pump, you may have to slide it forward (towards the front glass of the tank) an inch before lifting it out of the tank.
