Quarter Interval Timed Koralia?

[PoonTang]

I was running the evo models on on a timer at 10 second on/off intervals. They last for about a year before the little rubber button on the front cage breaks off. The good thing to is if you contact hydor and complain they will send you out some new parts. I have been doing this for 3 years now with 3 of them.

Well, upon monitoring for half a day...sort of....I've come to the end decision of leaving it on all the time and see how it goes.
I guess if I had a wave maker for every 10 seconds would be fine...but my 15 min , 30 min or even 60 min gap actually gave me a ill stomach...I saw my sixline wrasse swimming inside the power head around the blades...now one can only imagine what would happen if it got powered on at that moment...but ya, i will try to leave it on for a week and see, if not ideal i guess i will just remove it or buy a 1 or 2 .
