Things about my tank. I have a 90 Gallon aquarium with a DIY LED fixture with about 300W of lighting. I have mostly LPS, some softies, and very little SPS. Everything was doing fine about 1.5 months ago... so guess what I did? I slowly ramped up the lights on my LEDs about 10% slowly over two weeks. WHY DID I DO THIS? I added some SPS and wanted to see if they would grow faster. My lights don't ramp up or ramp down during the day. They just turn on to the brightness level they are set to.
Over the past month I have noticed my hammers, frogspawn and torches look kind of bleached. They are lighter in color and the tentacles are almost see through in some places. my torch coral is not inflating as much. The hammers will inflate but don't look full, and the tentacles look thinner. My frogspawn is losing color on top, but on the sides it looks dark green and pretty like it used to. I turned the LEDs down about 25% yesterday. I thought it was just the reflection of the lights on the tops of the corals at first, because my fixture is so bright. Now I am wondering if I shocked the FS, Hammers, and Torch. I will try to lower light setting for a while to see if that helps. then change locations to the bottom of the tank in case I have them positioned to high in the aquarium in another week or so to see if they color up.
now that you have some background of what I did what else could make just the euphyllia bleach besides the lighting adjustment? My candy canes are not bleaching, my RBTAs are happy and colorful. Has anyone had this happen? Or have a water parameter be off causing just the one kind of coral to bleach and not anything else? even the frogspawn that is on the bottom of the tank looks a little light in color on top.
