I have four of them connected to the squid wavemaker in my 58 gallon
aquarium and they work great- 2 on one side and 2 on the other. They are
made of a sturdy plastic and are well jointed so you can position them any
way you want.

Spotted these on marinedepot. Anyone used these? Look like they would get
stuck easily as coralline etc. grew on them.
