People who are bleaching how high is the fixture from the sand? Mine is 30 inches and I never dealt with any bleaching of any type of coral. I started at 30 for all 3 types of LEDS
ive had more growth with my leds then i ever had with t-5.maybe its because im testing every three days and i switched from doing a large water change to 2 small water through the week.also this is the first time i have gone all sps.im really happy i made the switch
