Difficult for me to tell with all the blue, sorry. Could you provide more info? Tissue receding? What's your photoperiod? Are you running any white light? Etc.
Noticed this spot about three weeks ago. Has continued to grow. It looks as if the polyp is contracted in only that area. Hard to appreciate with the white lights on as the tissue is a pinkish/beige and the coral color is orange. I can’t see any physical damage on that spot. The overall coral continues to grow very well.![]()

No tissue receding that I can tell. Just looks like the polyp won’t expand. I run my lights for 9hours a day. It’s the stock light for the fluval evo 13.5. Mainly white with a few blues mixed in. The only thing I can think of is that my blenny spits sand all over and some lands on it and I have to blow it off but that has been happening since day one. I’ve had the coral since mid April.Difficult for me to tell with all the blue, sorry. Could you provide more info? Tissue receding? What's your photoperiod? Are you running any white light? Etc.
Could be from the sand/blenny. Can you move it to where it wont be bothered? Could also just be an area that is deteriorating.

I’ll work on raising it. Thank youYour calc is low
He unfortunately spits sand at my other fish so it gets everywhere. Very irritating but also hilarious. Let’s say that the spot is tissue damage, is there anything I can do to stop it. I know with branching coral you can frag off the good tissue and “start over”. Since it’s in the middle is the anything I can do like that.Could be from the sand/blenny.

I use the Hanna ULR. I removed my gfo as they were reading 0. I have noticed a few of my other corals not quit as happy and I hope this is the reason. The lepto had this issue before my phosphates went to 0. Probably not helping in healing though. Thank youThe calcium is a bit low. But I don’t think that it is causing the problem. Calcium is easy to boost up. A little dosing of calcium would not hurt.
The phosphates could be the problem or part of it. I don’t know the test you are using. Hanna ULR is the only one that I know of that is sensitive enough. When my phosphates get a bit on the low side, my corals get unhappy. You could either dose phosphates, curtail your export (which you have done) or just feed more.
