Don't understand what is going on with these candy canes. Some diminish and respond back while others completely disappear. Had an algae scrubber break down for 4-5 days while away and nitrates went to 38. Got that under control and only fall-out appears to be wasting candy cane polyps. Any ideas? Photos 1-3 show trouble areas whereas #4 shows recovery. Other polyps have wasted away to nothing.
