I don't use it, reason being why would I want to reduce flow in my tank, I'm always looking for ways to increase it, I don't need a feature to reduce it 
Also since corals feed at night this is exactly the time I want POM to be suspended.
I don't think the fish care because they're hiding in some nook or cranny anyway at night.
The only benefit I can think of is if you have a shallow tank with too many 6200's the feeding tentacles of your corals will have a chance to come out at night without being blown all over the place.

I use the photocell because it seems the fish comes out to play at night . I can see the fish hunt at night for pods and do what ever fish do. Also for my lps the low flow allows them to get all their polyps out instead of half way at night. The sps seem to not care with more or less flow since i alread have really high flow using a photocell doesnt do much. I have it set to go from 50% to30% at night.
Same for me, The moonlight is a bonus as well. Pretty bright for one LED. Mines on the new multicontroller so it has the different moon cycles.
The full moon is sweet, My 190 gets a nice shimmer, and i can see my emperor angels hunting for critters. My achilles moves around with the manderin but not as much as the emp angels.
I think the crustations use it the most to hunt. The peppermints,cleaner shrimp, and lobster are always out at night.

I have been using mine.... Reading this makes me contemplate trying without it. It makes sense because in the moring I do get some detritus blowing around. Guess it just wouldnt be there if there were on there full power all night.
Question: In the ocean, don't the reefs where SPS(acros/monti's, mille's, etc.)grow, have a calmer part of their day?? Or is it turbulent waters at all times??

Someone correct me if I'm wrong but I believe currents in shallow waters are mostly wind driven and there is less wind at night when the sun doesn't shine.
Currents will still be more turbulent at night in the ocean than in the best home aquarium and attempting to recreate nature in this way has little merit IMHO.

I never used it and never will.

I disconnected mine about two months ago, and also noticed an immediate decrease in settled detritus. It won't be going back on.

currents are less at night, this is also very dependent on the tide which is correlated to the moon cycles not wind. Your above statement about currents still be more turbulent at night in the ocean than in the best home aquarium is not correct.
If you do scuba dive, have you ever been on a night dive? Sleeping fish, less current, closed corals..ect

Nope, I get detrius build up when I turn off my wavebox.

Re: calmer
Ever notice how when you can only see 9 feet when diving a reef because of suspended matter no detritus settles inside the valleys of scrolling turbinaria's and similar corals eventhough you can't feel any current at all?
I dive usually once or twice a month. At night there usually is less current, sometimes there is more because during the monsoon season many rain storms seem to come in the early evening. Also less fish but some fish that you don't see during the day like moray eels swimming freely. More crustaceans like shrimp, crabs and lobsters and lot's of other creepy crawlies that you don't see during the day, great fun LPS tend to be opened and SPS tend to have their polyps out etc
Re: calmer
Not more turbulent in terms of force, just more turbulent in terms of randomness, eventhough you don't feel it like when you stick your hand in front of a powerhead it's always there and passes in much greater volumes than would ever be possible in a tank, day or night

Re: Re: calmer
Actually, no very rarely do I. Not in 100+ dives in fiji. The only time was grand cayman diving the first 5 days after the hurricane. :rollface: If I could only see 9 feet of the reef I don't think I would bother diving.
Weather does play a huge part no question. But with the absense of a storm the current is rarely stronger at night. There will always be execption.
one last thought I was actually surprised to see so many acro's in fiji that had rtn'd and revoverd. I would see this huge coral half rtn'd half alive and I would want to frag them. You would see many that part died and than regrew over the dead part. Many with detritis on them. I was also surprised to see bleeching acros, & very colorful acros at 120+ feet. So it happens in nature also they just have more water volume to deal with it1

Hmmm I could have sworn I heard that night/day have no bearing on underwater currents, only the surface chop due to wind. I could be wrong though. Anyways I dont use the photocell
