Here are some pics of the new Orphek LEDs. We are getting PAR values of 600 a few inches below the surface, 300 on the substrate at the centre and 250 on the substrate near the glass. We are still running the MHL & T5 but only for part of the day.

Our two Bangai cardinals are a month old and almost ready for the display tank. We have two newly captured fry about the size of a grain of rice and the parents are still breeding. We had a few hundred Reidi sea horses last week but we didn't have rotifers ready to feed them. We will be prepared next time.

Absolutely amazing. You guys have done a fantastic job. I can't believe how great your tank looks in such a short amount of time! Can't imagine what this tank will look like in a year or 5 years! Good job.

Love the pics Thanks fos sharing.
I'm interested in the comparison of the LED and MH lighting? Do yo usee any clear difference in the areas lit by MH and those lit by LEDs?
Any comparative PAR values would be appreciated as well as a reminder on which bulbs and ballasts reflectors you're using?
Thanks

Mind taking a video of the fish during feeding as well? I'm sure I'm not the only one that would enjoy watching that!

The tank is looking simply beautifull. I love those engine room pics, some hectic equipment you have playing with.The led lighting on the display tank brings out the colours.

The Straylight plasma fixtures don't look sexy even after a 12 pack, but the yellow light is a warm break from all the high Kelvin blue light. The mangroves and chaeto are growing rapidly which makes up for our space limitation (quality rather than quantity). One issue we are having with the refugium is a floating green Cyanobacteria. There is no surface skimmer or movement so we are manually skimming with cups and nets. Part of the problem is the stray bubbles from the RK2, the bigger part is the 510- nm Straylight. I will do some dimming tests and try a 100 watt high bay LED spotlight instead.

The good news is the quality and angle of our new LED lighting on the display has not caused any extra nuisance algae on the walls, rock or substrate. We havent experienced any additional bleaching of newly added corals and the older ones are noticeably coloring up. This is partly to the credit of the quality of light, but largely due to the quantity and new coverage of previously shadowed areas (namely near the glass).

We have added a bit of heat, but no more than we had expected from 1900 watts of LEDs. The Mhl photoperiod has been cut in half so it averages out over the day.

The other lighting issue we are really happy about is being able to angle the lights inward a few degrees to illuminate the sides of corals & rock as well as mounting them up and out of the way for easy access to the tank.

Nice results. How long have you had the Orpheks installed and what have you seen as a result of installing them?

We are using Aqua-Medic magnetic ballasts with their small reflector. We don't have room for anything bigger. While large reflectors are great for tanks 3' or wider, I find they cause algae growth on glass, substrate and overflows. They also tend to project too much light into the room for a less dramatic display. Our compact reflectors were giving us 160PAR at the substrate near the glass and 200 at the substrate near the centre. This is pretty uniform coverage for a 30" tall tank with the fixture only 10" above the water. If there was no rock in the tank the coverage would be even more uniform.

We tried the old style Aqua-Medic electronic ballasts, but PAR and lumens were almost 50% lower!!! We havent been able to get our hands on their new improved electronic ballast.

I will do some more lux and PAR testing and post the numbers on a picture of the tank to map it out. I will also post the photoperiod ofeach light. The Mhl look more like natural light with a nice calm shimmer. The LED shimmer is a little faster due to the multiple points of light. When all of the lights are on, it blends nicely with a subtle mix. This was our goal since natural reefs never look homogenous. The 250 watt Mhl alternate between 13,000k Aqua-Medic and 14,000k Phoenix. Most of the usable and visible light from the Mhl is coming from the 13,000k bulbs. We ordered a more blue mix in our LEDs to cancel out some of the white look, but I still find white light to be more natural.

We had a 13,000k 250w mogul fixture on the tank during our testing; I think we could have used this fixture with a heavy blue mix of LED to drown it out, but overall the 250s were still the smart choice.

We had a browned out acro in the display that took a bit of a beating from too much flow and a few subsequent falls. We moved it to the Mars system and were shocked to see it turn a beautiful white with bright purple tips. After a month I moved the coral back to the display and positioned it between the LED and the Mhl. After a week it still has the nice tips but the white is browning up with zooxanthellae now. It still looks good.

The overall appearance of the tank, rock, corals and fish is a night and day difference. Peter had no idea how corals fluoresce under blue light. You just don't get the same effect with T5, and it only takes 4 x 2 watt blue LEDs in each fixture to do it. Over a 6' span, that's 20 watts LED vs. 78 watts T5 and again, a world of difference.

I'm not sure if this was covered or if this is information you'd like to provide but is there a rough estimation of electrical power consumption for the reef or a related cost?

This is just such a remarkable system...the progress in just the past two months is astounding!

How many times a day are you feeding the DT tank fish?

Again, can't say enough about this tank and all your hard work. Also -> great photographs
