Anyone Thinking of Dumping LEDS and going back to Halides

What amount of that full spectrum is going to be full spectrum at the depths our corals live? By the time the light reaches the corals, it has been filtered down to blue and green.
Which would tell me in nature shallow waters would see mostly red, deep waters would only have 25% of the originally moon light so really dim. Since we are talking about our aquariums we need to find a light spectrum that allows corals and fish to sleep
Or just skip the moonlighting. :thumbsup:
I have an original Lebos 3 light LED moonlight from 2006, I used it for about a year, it made no difference that I was able to discern. If my schedule made evening viewing short, I changed when my lights came on so that I could enjoy the tank when I was home.

Not necessarily, some SPS live at or just below the surface so they would be getting full spectrum while others live deeper and get less reds and violets.

But where do the majority of our corals come from? Deeper than 10 meters?

You must be looking at a different pie chart. I see mostly red and green.I always find it interesting to see how many people interpret the same information differently.
Are you saying just a red lamp? Or Add a red lamp with the blues? Because it clearly shows in several explanations and charts how the moonlight is a full spectrum light , with nearly 66% of it covering everything but the red part of the spectrum.
I think, for the purposes of this hobby, and the level at which a majority of hobbyists are at, blue led moonlights are an adequate solution. Once you start being really specific and wanting to induce spawning, well then yes, something like the full spectrum tunze moonlight might be a better option.

I have actually no idea what specific water depth our corals came from in the wild. I do know that corals on a reef can range from the surface to about 50 meters. Anything we do in an aquarium is a compromise. We may have one species that was collect in shallow water next to a deep water species and they will do fine under the same light.

except just 10 meters down, the water filters the light to blue and green

Since when did we start caring what color moonlight the tank inhabitants prefer? Or any lighting for that matter. It isn't like anyone bothered to poll them when designing the things. They just said "What color do you want to look at? Blue? Okay, it'll be blue." Same way we ended up with half the 'reef lighting' out there. "Too yellow? How about some more blue? More blue? Great, looks a bit like Windex now, but whatever works for you..." The fact that corals seem to be happy with it is a nice little bonus that came about afterwards. Moonlights are entirely for the enjoyment of the aquarium owner. Whatever color they want to use works.
Although I guess red moon lights could be interesting since you could probably bump them up high enough to make the whole tank visible, without disturbing a lot of the inhabitants.

Since we have been off topic for this page anyway, two years ago several of us from the local reef club walked out on the jetties at Port Aransas with red head lamps and I was amazed how the fish were not bothered at all. We even ran into a sea turtle, at which one of the members wanted a clear picture so he switched over to white. Bad mistake, turtle went ballistic and he never got a picture.

There is nothing errant in my statement : "with nearly 66% of it covering everything but the red part of the red spectrum."
If you look at the chart, you will see clearly that approximately 2/3 of the chart is "everything else but red." which 2/3 = 66%. So no, I'm looking at the same chart.
You may see mostly green and red but that doesnt change the fact that red is about 33% and the rest of the spectrum covers about 66% with a focus in the green of course. But I didn't say otherwise.
I am not sure where this "LED's are Cheaper" thing comes from. maybe if you have a nano cube... Buy light your 300 gallon with 6 good LED fixtures. That's almost $6k to do what 3 reflectors, three bulbs and 3 ballasts will do.
Anyway. OP... I am thinking of switching to T% MH combo on my DT. My DT is 2.5 years old and the party seams to be over with my LED's. The corals still grow but color sucks. and things are starting to die for no apparent reason. I put frags in my FT (that runs T5 MH combo) and with in a couple of months that frag grows faster, colors up quicker than under my LED fixture.
LED's are great. Buy it once, set it and forget it. But the corals just love T5/MH combos...

Good, so for you they are cheap..

Slightly different enquirer here but I happen to like my Solaris I-5.
I do however want to find some extra parts for it.
Harder & harder to find nowadays.
SO - if anyone has an I-5 and wants to let it go please let me know.
I have a friend that is interested in The "G" series for parts so that is another option.
Thanks --

Dumped the 4 reefbreeder value fixtures I had over my 80 gallon for 5 months and went back to 2 250 watt radiums in lumenbrights, with 2 48 inch vho super actinics. All growth and color returned after about 3 weeks and things have never looked better, colors looked dull and growth was very slow under LEDs.
