I have a 130gl reef tank, been established for about 2 years. my frog spawn has developed a hole in the middle where i can see the skeleton base. it seems to be spreading. i havent added any thing to the tank in at least 6 months. all my levels are good. Alk. is 7dkh, calc 425, ph 8.3. ammon, nitrate, nitrite are all zero or almost zero. I dont have any algae problems coraline is growing nicely, no deaths...
I only supplement with trace elements. there is no other corals near it. the edges of the coral open a lttle bit but the rest stays shrunken. have 4 VHO (2 actin, i 50/50, 1 10k) my other corals are doing great. im stumped.
