So I know this has been discussed already on these boards but I wanted to ask again. I have a few Acroporas that have become significantly changed color. They have become dark green and brownish in color. I have 60 gal tank with 2x150watt MH with 15K bulbs in each and 2xT5 with 420actinic bulbs. Calcium levels are good, but my dKH fluctuates a little (between 143.2-125.3 ppm). My tests show 0ppm of phosphates and 10ppm nitrates. Anyone have any ideas on how to get the coloration back in the Acros?
