alright, figured that out too. My old par with 250 mh's was 550 at the water. My new par even at 100 percent is much lower. I have it at 40 as suggested. What par should I shoot for?

[jimmy n]

What par should I shoot for? I have 2 6200s over a 120. The par currently is much less than my old 250 watt MH. I know this can be deceiving. I used to get 550 over the over, now I get about 100. This is on 50% intensity. Any thoughts? I keep my lights about 18 inches over the water. Should I dial it up or let it be?

[ReefRockerLive]

Is there a reason why you're keeping the lights that high off the water? I'd suggest having it lowered to maybe 8-10 inches off the water and keep the intensity at 50% for now. You can bring up the overall intensity by 5% every week until you reach about 70, maybe 80%.

Most importantly, keep an eye on the corals.

Yes there is. Less salt creep, less splash. If you can only keep you lights at 50 -80, why not lift them up and keep them away from the water? My only concern is a significant drop in PAR.

Can I go 100% to get the par to 1/2 of my MH? Would that be damaging? Should I go somewhere in between? I'm measuring everything. PAR. Alk. Ca. Mag. I want to see if all things are equal the Mitras are better. Thanks!

[ReefRockerLive]

You must have some serious surface agitation in your tank to keep it that high up.

Fwiw, I have my light 9 inches off the water and I barely get salt creep on it. I suppose you could keep it at that height and raise the intensity to 90 or 100%. The only drawback is that you will be using more electricity to achieve the same results you'd get if you were to go ahead and lower the light with a lower intensity.

Are you running the light on high efficiency or high output mode?

Wow, I'm Honored, to see my tank here in this thread, the pictures are not recently taken, they where shot a couple of days after my LX 6100 HV arrived, by god what a difference in growth and coral colors, i can see now after 1 year. Hooray for Mitras. but i will try to post some new for you guys as soon as possible, in the meantime you can see new pics in my danish thread's.
My tank by the way, was Choosed as TOTM on the Danish Saltwater forum for November month, and i thought about translating the thread to English, and post this on RC. But for now, here´s the link to the danish site. http://www.saltvandsforum.dk/viewtop... f=138&t=63664 , where you can see newly taken photos of my system.

Go to energy settings, change lamp to high intensity then the max intensity to 100% from the default threshold of 80%

to toe composer and set the lamp to 100% and click on the tab at the top for direct output

put sunglasses on and stand back!

In all seriousness if you are running the lamps out of spec at 18" above the water line then you need to use high intensity mode and also ramp up the energy threshold to 100%.

[jimmy n]

Thanks for the responses. A little more help.

I figure for dimmable moments the first one is on percentage and the last should be 0 or off. However I got up at 6 and my lights were on. Am I wrong? Also at 10 there was some blue on despite the fact that my last dimmable moment was zero. Thanks in advance.

[AQD_ottawa]

You have the default moon phase ticked, go into illumination channels and un tick the check box for moonphase in each channel that it is ticked in, this is the only time you should ever go into illumination channel and touch anything also

Please also look at the video I did
https://www.youtube.com/watch?v=-7txuIXMdB4

[jimmy n]

Appreciate the response, all were unchecked and I'll see how it goes tonight. I thought the illumination channel was how I adjusted the light to how I like it? Am I wrong?

[AQD_ottawa]

YES! do not touch the illumination channels its done in light composer ONLY.

please email me I will send you my project this is a starting point to learn from. info@ghlna.com

We have had our first entry to the Mitras Project section on www.profiluxowners.com.

Thanks Aaron Down!

Thanks Aaron Down!

You're welcome. Let's hope more people add theirs. Should be excellent in the long run.

[Anim8me2]

I really hope so! We need to build the community up!
I'm tired of people asking me what the profilux and Mitras are.

Thanks Aaron Down!

Great idea Ian , but can you list which Mitras each projects are for. The 6100 is not compatible to the 6200.


Kevin S

[Anim8me2]

Great idea Keyvan! You got it!

[Montanero]

This is great, I've suggested that GHL do this and that didn't go anywhere, I am glad to see that you've taken the initiative to get this ball rolling. Thanks.

The Mitras are excellent fixtures and I've seen coral growth that is beyond expectations since I installed the pendant. This will be very useful for new users.

[Keyvan S]

Looking for 6100 light projects.

Thanks

Can some Mitras users, not AQD_ottawa , give me their opinions on how many units I'd need for a 96x36x30 tank? 3 units in - - - or 4 units in | | |, or would I need more? SPS tank, open rock work.

Seems LED users sometimes get surprised at times with coverage and end up needing more units down the road with shading etc.

[AQD_ottawa]

hey why not me I will tell you need less and save you money

i have 72x36x25 tank and i use 4 units for SPS tank. for you size i would go with at least 5 maybe even 6 in this order IIIII

[AQD_ottawa]

Mike seriously! no way, the spread is under rated at 36x36 we had 3 on a 72" tank at macna that was 36" deep and have massive overspill, you saw it yourself.

I dont know a single person having more than 4 on a 96" tank honestly, more than 4 would be just nuts.

Our professional suggestion would be expect 4 units for balancing but start with 3, but absolute no way at all more than 4.

[MSHUR]

Michael,
you right for LPS tank but for SPS i feel that more light required , JMO Specially with open aquascape like i have in my tank, 4 is perfectly enough .. I keep some LPS on the sides and they doing great...But my SPS need more time to color up , i guess

[MSHUR]

Again, i am coming from Radiums 400w . I love a lot of light, so my SPS )
