Please help to find device
I'm looking for device for aquarium, but I don't know how it exactly looks like and its name. I only know know that it does exist.
It simple motor-less pump with Y-type hose connector. One hose attached to tap, another one immersed into aquarium and the last one goes to sink. Pressured tap water flows through the pump and pull the water out from aquarium. The mix of tap water and aquarium water is drained off to sink.
What the name of this pump? Where to buy?
Thanks a lot!
