[TD="class: alt1, bgcolor: #EBEBEB"]I have been keeping SPS for about 5 years now so Im not new to it. I recently redid the tank and have had great growth and color on an all acros in the tank until about 1 month ago. I have had a few small colonies start to receed from the tips, lost a hawkins and an icefire, but am seeing the same thing on a few other colonies. I watch a few tips almost look burnt, then a few more, then it starts receding. I have not had any big alk swings to justify burnt tips and I do not see any signs of AEFW or red bugs everything was dipped in bayer and qt for 6 weeks before adding to display. Any advice would be greatly appreciated. Im thinking of adding Lugols to see if maybe the Iodine is depleted, but im grasping at straws, nothing has changed and half the colonies look great. I do not do frequent water changes. I do about 5 gallons every 2-3 weeks and use salitity salt Here are the spec below.
