I recently downgraded from a 120 to a 55. I moved all my rock over, added a 3" sand bed and replaced my metal halides with LED
. The tanks been running about two weeks now and my Duncans are not coming out and it looks as though I've already lost one of the heads and its showing signs of being bleached. My galaxia it turning a brown color with bleaching on the very bottom. My trumpet coral seems to be beginning to bleach. However, my kriptonite trumpets are as green as ever, my pulsing Xenia are fine, my pipe organ is fine my two star polyp colonies are also fine. Could the ones that are beginning to bleach being starved? I also took 55 gallons from said 120 when downsizing. I haven't been able to check parameters as I'm waiting for my new test kit to arrive. I know it may take some time, but 2 weeks and my Duncans still have not come out, I'm starting to get a bit worried.
