I have a fish tank which has a fountain on the top,which trickles back into the tank, filtering and giving air. The pump I had stopped working and the fish were becoming upset, and bored. I searced for a replacement to no avail. I came across this pump, and thought it might work, though it is just designed for a small indoor fountain. It is perfect.
The fish are now happy and content, the tank is clean, and the fountain is giving sparkle back into the room.
The pump is small enough to go in the tank, without getting in the way. The motor is extremely quiet.
The unit itself was simple to put together, and the flow of water was easy to regulate to give just the right flow of water for the fountain to flow without going too high.
