Corals Getting Green

R

I have had my tank up now for 1.5years.
Some of my sps frags, cali tort, rainbow monti, purple bottlebrush, and red planet are starting to become predominately green in hue, and loosing some of thier other colors.
my cali tort for example was 90% dark and light blue, but now everything but the tips and polyps are a beautiful green. I dont mind the color, but other multi color corals like red plant are loosing thier red and becoming more green.
Not sure what is causing it, but i thought i would post to see if anyone had theories...
Using two 175w iwasaki 10ks, 2 54w actinic, and blue leds.
Growth and cal / mag/ dkh are all good.
 
Might try iwasaki 15k bulbs. I had good results when I used those. Might try dosing koral color from brightwells I am getting great color once I started dosing it.
 
using koral color, and i am wondering if that was cusing more green to show.
nitrates and phos are un-readable on hanna and api test.

somone on RC said it might be caused by longer light cycles...

On a side note, does lower kelvin rated bulbs like 6.5 - 10k cause different colors then 20k?
 
Lower Kelvin in my experience cause the corals not to pop in color but they do grow faster. I prefer 14k to 20k look
 
The 10K bulbs can cause color's to not develop or pop as well. I would bet that phosphates are also present and not helping. Phosphates should be less than .045 in a reef tank and a lot of kit's out there are not sensitive enough to accurately measure that low.
