From the looks of it, your lights are 10-12" above the water and your corals are several inches below the water surface? Am I seeing things correct? If so, you might want to slowly increase your intensity over the course of a couple months. I would suggest about 1-2% a week keeping a close eye on the corals to make sure they don't respond badly. You may also want to reduce your color a bit. Maybe down to 60% over the course of a couple weeks and see what that does. I would wait until you have increased the intensity (Assuming I am correct about the height above the water and distance below the surface) first before changing the color or do the color first followed by the intensity. You just don't want to make too many changes at once because you won't know what caused an issue should your corals respond adversely.
Hi Scott,
Nice to hear from you again .
You are right , my lights is about 11 inch above water surface and corals is about 12 inch below water surface.
You mean I have to gradually increase the intensity for about 8% - 16 % in total? Considering about 1-2 % / weeks for couple of months ? Ok , I will make adjustment first on intensity and then see if corals is ok with that . Furthermore , as I understand what you suggest is intensity first before colors or colors before intensity , can I make adjustment of both gradually at the same time which means increasing intensity 1-2 % per week and decreasing color 1-2% per week at the same time ?
I am suspecting that corals also react to my present high po4 (@ 0.18 ppm) but I also suspect my lights has to do with it too as in the past when I have ULNS thru Biopellet corals already response like this , it just so happened when I switch to KZ and its does not work well for me that causing my po4 unable to lower down Inspite of continuing dosing so now I switch back to BP and trying to reduce my po4 with GFO too. (Anyway , this us another topic).
Cheers,
