hi this was the first frag i put in this tank which is about 5 months old the first 10 days they were not opening up all the way. after doing some reading i realized that i had my lights to high so i lowered them in the tank and lowered my leds to 40% blue and 30% white. they have looked great for the last few weeks but i just noticed this white stuff in between the polyps. this pic is after th lights turned off cause in the day time the polyps cover it up. any ideas would be greatly appreciated.
Thanks
Thanks
