At Fish Ranch, i noticed in some of their tanks, the output on a powerhead goes to this little gadget that swirls in a circular motion. They look a little goofy, but I'd like to have more water movement in my aquarium.
I've tried to look them up, but i don't know what to call them.
What are they called? Does anyone have experience with these?
