Is there anyone here who is doing this, and if so how is it working out. Is the Seio capable of operating on an on/off regimen. What im trying to accomplish is a calm sea effect. Im getting mad extension from my LPS and my shrooms get huge with less flow in the tank. When i turn off the Seio for a small period in the day, everything just blows up and gets crazy swollen and huge. I believe Rick in NO used to do this in his SPS tank, but not everyday, maybe just a couple times a week. Ive even heard of people simulating rainy, cloudy days maybe once in a while by only running the Actintics for that day, is there any positive outcome to these simulations besides realism in duplicating nature. Im really more interested to know if the Seio can handle the on/off sequence. I turn it off for about 6 hours in the middle of the day. Any feed back or opinions would be appreciated.
