GHL Mitras Club

I usually drop mine by 30 and go up 5%per week depending on the coral and where it's coming from. If it's coming from an led set up or a high light coral, maybe I won't go as low but my increases are always in 5% increases..
If it's a deep water or from a t5 tank, I'll drop 30% and go from there..
Unless I can find a very low spot in my tank, then I don't worry as much..
I'm talking acropora, by the way..

Hey Sahin, thanks! I'm holding out for your fts! :)
Actually, I'm mulling over starting a thread because my tank is not exactly where I want it to be and I think I'm experiencing some common reef problems..

I use two giesemann aquapinks and two giesemann lagoon blue bulbs from 10am to 8pm

Mike,
I like that mix better..
So you have a considerable amount of light- 4 Mitras over a 6 foot span. I'm not sure you need to be running them on HO.. You might want to put the light into HE mode and run them at 80%. The tank will seem much more dim to you but the corals might be happier..

I must say, I'm not entirely comfortable giving all of this lighting advice as I'm really no expert.. Experimentation is really the key..
The only thing I feel is really important is to err on the side of too little light because corals don't get shocked from too little light. But if they get bit by too much, it can take months for them to recover and you'll be scratching your head wondering why the coral is doing badly even though you lowered the lights a long time ago...
Like everything that happens in a reef, the damage takes an instant but the recovery takes forever...

I have a 255 gallon rimless aquarium. I was a die hard MH user before I switched to LED's well over a year ago. I have a mixed reef with lots of sps. My aquarium is 72" long by 29" high by 27" wide. When I switched from 3-400MH setup with two 72" VHO actinic lighting, I was advised to go with 3 mitras for my setup. I setup the lights out of the box at 100% output, being careful to only max out the whites for like one hour of the day.

This worked real well for me. I never seen any bleaching or issues with that setup. Now that being said, some of my sps were not doing so well(those that were deeper in aquarium or required more light). I played around with different settings, until I realized that 3 mitras was not providing enough light for the light hungry sps that I had.

Don't believe the hype that you will only need 3 units for a 72" setup like mine, unless you have corals that don't need allot of light. You will most likely need 4! Let me explain.

In short once I upgraded to 4 units and all my corals that were not doing so well with color and kind of fading have colored up and are awesome. I wish I would have went with my gut feeling from the get go and got 4, then I wouldn't have to wait for those other corals to color back up. Oh and yes, the unit is on 100% output.

Thank you for you review. Do you have 6100 or 6200? any chance you can share you program?

+1.
Thanks for giving your experience.. This is why one can never just assume that lighting is the be all, end all... Clearly, lighting is just one element that contributes to coral health and colour..
I'm surprised that you can run them at 100%.. I hear this every now and then from led users and it always tempts me to try upping my intensity...

I have the 6100's. By all means I can share what I started out with and what I have now as well. Just let me know how everyone is sharing that information now. My original program came from seller of the lights. Great guy in Houston TX. His knowledge of the light, and all the support he gave me was well and beyond what was expected, and that is what got me to fall in love with my mitras right out the box. Back then there were no projects laying around and he gave me a starter one to go with.

He had been using the project for his clients he sold them to and ensured I wouldn't have any issues and he was right. The power was at 100%, but only the UV came on and went to 100% intensity and pretty much stayed there the whole day. Only one white ramped to 100% for one hour in the day and ramped back down. I cant remember where the other white ramped too. I will have to reload it to see it. The only problem with the original lighting setup I had, was that he had too much red led in there, and it caused a little algae issues. I ramped that stuff way down.
 
I want to express my thanks for the posted projects. I am using one and I love it! Excellent work on the projects and the website where they are posted. Kudos!
 
Yes I can. I will take a few shots of the aquarium and post. I have some old ones as well. That project I put up is the one that was given to me when I first purchased my mitras, and I migrated from my 3-400watt Radiums and vho actinics. I have made allot of changes to that one, and that is not what I use now. It worked well as a transition. I think I remember back then I had to make a few changes to make sure the lights turned all the way off at night and etc. That project is the one that I had to take the red out. I only had three mitras back then as well.

What I will do now is log into my lights and save the current project I have now off and post that with the current pics of the aquarium. I think that is the one people will want to use more. Just wanted to clear things up.
 
I'm using one of the first two uploads from the site. I'm brand new to mitras (Christmas time), my hard corals are encrusting and starting to show some growth. Not bad for a month and a half.
