Has anyone had zoas growth rate slow with switching to LEDs? I got some eagle eyes from a guy and he said they were growing fast under halides in his 240gallon. I put them in my 7.5 gallon cube about a month ago and they haven't had any new growth and have changed to more of a purple center instead of orange. I have the new 7 led par 38 bulb from rapid led and nitrites are 0, nitrates ~5ppm, and calcium is around 410. They look healthy and always stay open i was just wondering if anyone else has had this happen or am I just being too impatient.
