hydor flo

[gobytron]

They come with attachments which fit on a variety of powerheads.
These are one of the simplest wave simulators you can buy IME.

I swear by these in smaller systems.
They fit right on to stock aquapod and biocube fittings and really make for excellent laminar flow in those systems.


Not as diverse or as powerful as a tunze or vortech but for what it is and excellent product.
