looking good! no signs of bleaching. bump your whites up a touch, or bring the colors down and that will help with the purple tinge. the red leds sometimes are a little over powering until you get things adjusted just right. Save the remaining 25% of the blue power for when you start trying to keep SPS incase you need extra PAR and now just tweak the white and colors to get things looking even more fantastic.

Even if it is just the camera the corals and fish in the current pics look a thousand times better than your before pictures.

Thanks - I wish I could find a local PAR meter to borrow -- I'm curious where I'm at but I guess not curious enough to spend $300 on a meter to use once or twice...

I still can't figure out why some of the LPS I have are STNing... Maybe they were too far gone when I added the lights but I had a small open brain that has receeded abck to the mouth - it was probibly at 40% when I switched the lights and it's continued to receed - it's at about 15-20% now. I also have 2 heads of green candycane. As fo last night, 1 head was totally gone and the other is about 10-15%. I have some hammer - the only other LPS I have and it is doing great - I guess I'm hopeful that the stuff was just too far gone to recover. I'll have to get some SPS frags (millis or acro - the montis I have are doing ok) and maybe 1 small LPS of some sort and see how they do if they start off healty.

Do't bet your corals on a PAR meter. Most if not all inexpensive PAR meters loose sensativity under 450 nm and over 640 nm. Yet Corals prefer lighting in the 420 nm to 460 nm range. With LED's your strong in that short wave lengt range and your corals are getting more than most PAR meters are claiming. For feresh water plants and algea PAr meters are much more usefull that for coral growers.

The main factors is you have enough blue light 420nm to 470 nm to make your corals happy, and enough white light to make your viewing pleasurable. The last is the hardest to extimate as everyone has there own tastes.

As far as your corals go I have found LPS corals seem to have a lot more recovery potential than SPS corals. Very often when somethng went wrong the SPS corals continued to die even after the problem was corrected.

Thanks Dennis. That all makes perfect sense. I just can't figure out why the 2 LPS are continuing to recede... I had some skimmer issues with things running too wet and maybe my salinity is more off than I realized. I'll check that tonight.
