I have no nitrates. I can't get cheato to grow my magroves grow very slow and I have a algea scrubber that been running for 2 weeks now. I have also been using prodibio for 12 weeks. I have been testing water biweekly. Two months ago I had a po4 problem but have since rectified it. I run a mr1 reactor with phosban. I have great colors in Sps like garf bonsi. No other corals are off colored except a purple digi which brownish with purple tips.
I also have a white and fluorescent yellow frag of my brothers on my frag rack which has maintained color.

I have three 250 watt Mh @ 20k. Two t5 @ 10k. Two antinic t5
