Hello everyone,
for few months now I have a problem with my trachy. It all started when my favia began to loose its tissue from the outside of the colony and it was progressing towards the middle, and finally after few weeks whole coral was gone. The edge of the colony on that time was white jelly-like tissue, around 2 mm thick. Had no idea what caused this.
Some months after I've noticed similar situation on my trachy, the edge of the coral, where it touches the skeleton, began to appear white, then became jelly-like thing, just like on favia. I tried dips (Coral protec, AF dip), as well as Iodine dip, RO water dip, mechanical cleaning. No results, after few days the jelly came back. Now, like half year after, maybe even more than that, coral is starting to look bad, today I've noticed a little bit of skeleton, which shouldn't be visible.
I don't blame parameters cause every other coral seems to be fine. But who knows... In gerneral - Salinity is 33ppt, I try to keep kH at 8, pH is usually above 8, up to 8.3, NO3 around 5 (during favias death it was lower). Last ICP showed deficiency of Iodine and Strontium. Tin was above normal (0.0573 mg/l). This or next week I'm gonna do another ICP.
I attach some photos and a video and ask you guys for help. What is it? How can I help my coral?
Thanks!
