Quarter Interval Timed Koralia?

[DACJ]

I have decided to buy a new power head for my RSM250 seeing that one side of the current is weak and I got lots of rocks inside so decided to put an extra flow there, yet to find out that I bought 1 size over what I actually needed....so the water flow is a little big too strong now.

What I did then was to put the koralia on a power center and have it adjusted to 15 min on, 15 min off, from 10:00 and off at 21:00, so the live stock would have a break every now and then....

Now, my real question, is the power head going to last ? or I am just asking for trouble by doing this? I am pretty sure they weren't built to be used like that.... Any ideas?
