For water flow volume (strength), the Nero is between MP10 & MP40 based on the spec sheet.
Diameter of the Nero is 2.8". Its quite close to that of the MP40 (3"). Flow is quite wide.
Took a short video of just the Nero5 turned on. All the other wavemakers are off.
Can see its quite powerful. Able to push water all the way to the other side of the 5ft tank. Personally I like a lot of flow in the tank, and have rock-scape limitations.....hence the multiple wavamakers.
Set up yours yet?
