well, darn it. Why is everything else still alive, then? I have a 30 head Duncan, 7-8" monti, huge GBTA and those are all happy as ever! This is why I think I am done with SPS. |
FYI, Montipora are SPS. The troubles seem to have hit only the Acropora, right? So far, anyway. It was the combination of: 1. the change of lighting, 2. the broader spectrum of the new light, 3. the extreme intensity of the new light, 4. just one single day of fatal exposure to the intense full spectrum light(including UV) and the final blow, 5. Alkalinity below safe range and who knows what other parameters were on the edge for Acropora
I'm really sorry for your troubles. I've been where you are. Lethal coral sunburn is hits quickly and is hellish in its aftermath. One final thought. When you decided on this dual 250W MH as a replacement to the LED light over this 40 gal tank, did you seek our advice about it specifically? In asking this question I'm not trying to offend you or anyone reading this, just observing a recurring problem with hobbyists coming here to the forum for help; lack of follow through. It makes me sad.
Aloha, Mark

Mark, you're correct-I should have asked here. I honestly thought I was being careful. It turns out I wasn't careful enough. It's all good, though. I don't have thousands of dollars in coral and this won't ruin my day. I've been in this hobby long enough to understand the possible ups and downs. It could have been much worse.

I did have thousands of dollars in coral which I lost to sunburn, three times(3 seasons), before I realized it was happening. That put MarksReef Coral Farm behind by 18 months and is part of the reason it eventually had to close. Se la vie. Aloha, Mark

From time I added coral until now is 3 years. That being said I have cut, hacked, replaced, sps like crazy, sometimes fist size colonies, some have gotten so big I have just given them away (Bob comes to mind). I also ran 1 light only for 1 year before I added a second. Like that red planet, got too big so its gone, kept a few frags as you can see when comparing the 3rd and 4th pics.

Bryce is one that I place in the group of hobbyists that has a "wet thumb". From the start he seemed to have a very good handle on keeping a reef tank. I visited and saw his tank around the time of the second pic. Cheers to Bryce.

Awe thanks Mark, someday I do want to try a metal halide set up just not on the tank I currently have.

Bryce, I am impressed with that growth. You must be doing a bunch of things correct as well. I think I will probably stick with LEDs for the foreseeable future. Although adding some 150w halides to a much larger tank than I have now might work!

My buddy Evan127 motivated me to post up my settings vs email them out . It is not all the night data points as I do have some settings for a moon effect that change a little through the nite but it is the main daylight settings. I sometimes change the start and end times for daylight savings and I may have bumped each data point Brightness (not the color%) up buy a few % (1%-5%) since I took these screenshots. These settings are not going to give you those color popping blues in the middle of the day, you only get that in the morning and night (typically when I am looking at my tank). Late morning to late afternoon its going to be pretty white. I have two lights on a 65gallon 8 inches off the water.
