Hey what was your par readings at low and mid ? Is this why you think some of your coral lost color like we discussed at Richie ?
Absolutely here is what I posted on another one of my threads.
UPDATE
After much thought and debate I finally figured that it was time to see what PAR I was getting from my light fixture. The reason was my SPS just don't have the color I was looking for, So I asked a member (friend) from the local club and he lent it to me. Well to my surprise my PAR readings were ultra low so low I don't know how I got any color at all. I was getting readings of 80 PAR 15" FROM THE WATER LINE.
Here is what I did wrong
Light fixture was 8" above water line and my intensity was 65% this was all wrong for my tank. Below is what I did to correct my PAR problem and I know it's not been more than a day but my SPS are reacting perfectly, they all look better after 24 hours lol can't wait to see what they look like in a month. If I keep the fixture as I may jump into a mitras ghl
Also I have it set to acclimation mode over two weeks starting at 65% intensity and going up to 75% The reading below are all it the 15" mark directly under the fixture. now most of my sps are ate the height but I do have some that are closer to the light and they are getting 350 par to 380 at the 10 to 8" mark. before they were getting 150 max so I am so happy that Bill lent me his meter.
**** Note anyone running LED'S really needs to stop guessing and measure your PAR YOU WILL THANK ME LATER
This is what I did
LIGHT FIXTURE WAS LOWERED TO 5 ½ FROM THE WATER LINE
Raised intensity to 75% max at peak
Here are the results ENJOY AND HOPE IT HELPS RADION USERS.
