ok trying to figure out why i can no longer seem to grow xenia after it thriving for 8 months and taking over. which i was happy with. i just love it. Any way thinking back to when mine crashed.... gone in 3 days time. i had a heater issue, and i believe its when i started using carbon ( i dont think the brand matters) i have heard it thrive in dirty water and in clean. soooooo?????? why cant i get it to grow in my tank again i know its a funny coral and its not really known why it does this. how long have you had it in your tank? do you run carbon? a skimmer? bio pellets?
