That price is right on the money if it truly does up to 5000 gph
The Tunze Turbelle Stream 6100
which does 4000 gph
costs just as much.
I like the idea of easily being able to place it wherever I want, the no heat aspect, & the smaller foot print it takes up in the aquarium.
Only two downsides that I can see:
It could be easily removed/bumped by children if kept on the sides limiting it to the back of the tank if worried about it or do not want to view it sticking out the sides of the tank.
I love that it can be put on a controller and that the gph
can be controlled as well but I do not see any way to direct the flow if needed.
