"I have my Tunze on full power for 30 seconds" doesn't really identify the water movement.
A lot depends on the rockwork structure and the direction the power head is pointed vs the placement of the coral.
Agreed. In my setup, the Tunzes are at opposing ends facing each other, simulating a wave. Moderate rock, flow is above rock, but wave hits most areas.
The comments are more for personal reference in the code
