So I have a 6 month old bio cube that I have removed all bio balls and I'm running full apex with Dos. I have Chemi Pure, Phosguard, and Bio Pellets in back sump. Tunze 9001 will be in tomorrow. All my water parameters are fine when I checked this morning except I couldn't check Mg as I am out of the test 1. I run a Kessil 360 about 6.5" from the surface and the 2 corals in question (ONLY) are my spongodes and my setosa. They are middle to high in my tank and first noticed the spongodes not fully extending after I made 2 changes which I'm sure one is the culprit. The setosa started to lose some of the color and take on a blueish white but not bleach white. I lowered them both to the sand bed for now. So the 2 changes where dosed 1 center cap of ions Aquavitro and a few days prior I raised the kessil up 5%. All my LPS and other SPS are doing fine as of now. I haven't been feeding plankton or coral amino as I had some brown sand algae issues. Lighting is only on for 8 hours a day with the intensity of the Kessil maxing 30/35%.
Edit
I forgot my Green Slimmer is alive but browning not bleaching also. Animal is still green but the skin is brown.
