PH and Wavemakers

[jejton]

Why can certain powerheads be used on a wavemaker but others can't? Try to keep the technical language as lay person friendly as possible. Now if a PH can't be used on a wavemaker, like the earlier koralia's, can they still be set on a timer or controller, to shut down once or twice a day ? I have a third koralia thats currently not being used and I would like to use it but have it shut down at night to give the fish and corals some less flow. Would that be a problem?

the rattle from constant shut down and start up may destroy the power head much faster than normal use.

I don't think that's accurate.

AC motors make max power during start up (0 RPM). I think this surge is what wears them. (Most controllable power heads are DC).

Is this correct every one?

whatever something like that, end game is still the same, shorter powerhead lifespan.

I agree with killer, it shortens the lifespan of the powerhead/pump.

Ever unplug and then plug in a powerhead? I would say most of the time I hear a loud rattling for a second or two and then it starts running smoothly. I'm sure doing this multiple times for the day would have negative effects.
