Quarter Interval Timed Koralia?

[DACJ]

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 .
