Thanks Guys.

I have an update.

I'm considering changing the lights to led fixtures as a replacement for the MH and T5 light system I had.
I hanged 1X120 watts led fixture (left side) instead of my 400 watts metal halide - Giesmann fixture. The light is surprisingly intense, penetrating easily the 35 inch deep tank (Even better than my 400 watts MH). One issue is eliminated. I was worried about light penetration of led.

My plan is to use 6 led fixtures for the whole tank and get a higher intensity in the future.

how long do you plan to test the LED fixture to see how your corals respond with regards to color and growth? have you compared PAR values?

I don't have a time frame for the testing but my guess is that it won't be too long(weeks I guess).
I didn't check PAR values but I don't have a doubt that the led is much more brighter and penetrates deeper. MH light spread is wider, no doubt about it, so more fixtures are needed for the same area.

Can you take a picture of how your front returns are connected?

Thanks

Those original pictures are great for the pipes in the front of the tank. I would like to see how they connect to the outside of the tank. A bulkhead through the bottom, over the top, etc.

Thanks

Look here.
It's not connected through the bottom with bulkhead.

No problem at all
My old Sohal was not aggressive at all. The reason for replacing him was his size. I try to keep smaller fish and bigger variety.

Ok I hanged 3 fixture in the left side.



Left side:




Color is more natural and less blue. Led light is much more intense than 400 w metal halide + 6 X T5 (54 w).

Awesome tank - congratulations. Love the tangs - do you have a current fish list?

Thanks.

what are those led units? What are your observations so far?

What an amazing, enviable tank. Truly something that makes people drool.. I can't even imagine how to squeeze so much into my tank.

Thanls guys.

The led units are from Orphek. No observations so far except the drop in temperature levels and algae growth is cut by 80% on left side front glass.
The led units are only few days above my tank and I expect changes only after few weeks (hopefully).

I don't have a current fish list but I have about 60 fish with a wide variety.
Same way with corals. I buy them small and enjoy the long years I grow them.

After two weeks of experimenting with led, some updates:

In the last two weeks there have been several changes, some of have been reported, I will summarize:

1. significant drop in water temperature.
2. Increased polyp extention.
3. increase coral growth in some acropora's.
4. No significant color change.The corals were colorful remained unchanged or just cleared perhaps because of the additional hours of lighting. MH were 6.5 hours of lighting and led 10 hours of lighting. brown corals stayed brown but became clearer. I expect more.
5. Algae on the front glass was reduced to one-third or quarter of the situation befor. The reason is probably less lighting on the front glass and less spectrum that encourages algae .

Please note the Acroapora in the middle. Increased growth can be seen in the bright purple areas.




Blue stayed blue. After two weeks there is little clarity in color. No decrease in intensity.



Brown corals which were once in the past a little pink color haven't changed but cleared .



This coral was a brown pink and had no color change yet .



Greens have become more vivid bright under led lighting.



Orange red color looks excellent even better than before (the image does little injustice to coral ...)



I really want to see what led can do to the right side of the tank where there are some corals that I think will respond extremely to led due to their type (badly or great improvement and less static), but this experiment would be too expensive, so I will give up on it until I see significant results on the left side.




I will summarize the last two weeks :
The led technology in my opinion is already in "prime time", I have no doubt. Light intensity shining on the corals is very strong, it can provide full lighting for extra hours and still save $$$. Corals look good and not react badly led light, no color reduction, no tip burns.

I think a combination of LED with colored T5 will be an excellent solution for reef lighting today and the future.


In any case the experiment goes on and I will keep updating.

Fantastic looking tank! Thanks for the information on your observation with the led lighting you are using.

It's a little scary changing lighting on a tank full of healthy, colorful corals. Even moving a coral higher or extending the photoperiod can cause brown-outs and bleaching. I'm glad the new lighting is working out well for you.

I have recently added 16 Orphek PR 156 fixtures to a 1350 gallon tank and have had the same good experience as you. The photoperiod has been extended so the reef can be enjoyed for two more hours.

Have you noticed a big difference in the blue dawn/dusk light? It makes my old T5 actinic look like cheap Christmas lights
