    I think I'm gonna give it a bash. First sign of distress I'll stop though. I look at it this way, surely natural reefs also go through periods of overcast during which times they receive little sun light. I know it's not the same, but similar.

    A friend of mine had a huge HA outbreak. I turned his lights off (he was away) for a week. Had Kalk dripping slowly into the tank. After 2 days you could see the HA was dying back, at this time the skimmer (Aquamedic SL 1000) was pulling out dark gunk. After one week put the lights back on. Almost no HA and the water was very clean.

    No it was a FOWLR system. He had some Zoas though. They were fine afterwards. I have turned the lights off in my tank for 2 days (Mix of soft, lps and sps) and the corals were fine after 2 days.

    I'm really keen to see how this is going to turn out. I've also see ppl turning lights out for 2 or 3 days to get rid of ich.

    Note: for the record if it fails and Reeftoi sells all his kit i have first debs.

    from what ive noticed,after clearing up all my deadspots by removing all my excess LR allowing more flow there has been less algea issues.

    The way most of us light our tanks is pretty unnatural, yes, but even more unnatural would be no lights for three days!

    was going to post a thread on this until it showed me the key words so i'd love an update. Has anyone tried this? not to combat algae but mainly for the proposed affect on the system? It has been said in the thread that the pods multiplied like crazy and its possible that there were growth spurts during the dark period, does anyone have any experience with this? i think with strong MH re-acclimatising corals would suck afer three days of darkness, but if there is indeed a positive effect on the system without any of my corals dying i would like to do it, maybe once every two months, for less time so the shock isnt as bad? I think if one's tank is matured enough a pod increase is not really going to be such a magnificent thing as the pod production would possibly already be high, and growth of corals would probably be pretty adequate as well. So besides trying to copy the ocean more accurately is there a definitive advantage to doing this? being able to add live-stock with less bullying is a good thing, but other than that? i got up to the 20th page and then gave up. Sheesh 41 pages of back and forth.

    I think Irie Ivan's post said it all, the reef system without light for two or three days at a time is entirely unnatural (even with overcast days the sun's UV rays still penetrate) personally i'd try to keep the lights on a cycle, with moonlights etc for the most natural lighting method possible in our tanks.

    Personally i dont see any advantage to doing this, having said that no harm will come to the system if the lights [not all power] were turned off for 2-3 days for maintenance or repairs.

    I`ve cut all lights for 3 days twice now but only once a month, colourful sps definetely brown a little but otherwise no noticeable pros or cons. It was an attempt to rid the system of green cyano which appeared to be less but after two days of lights again it was back to how it was.
