Loss of tissue

Does anyone know this type of tissue loss at the base?
One week of difference in each image
Thanks

Could be multiple things. Such as pest, parameters or too much flow. Hard to say for sure. Any neighboring corals that could sting the Acro?

Seems like low alk or salinity high and excessive flow .

Thank you for answering so quickly, under a little alkalinity, now it is corrected, my flow is very high because my aquarium is sps, I have some coral of the same species and have not suffered loss of tissue

thanks

Most likely Alk or flow. If other acros of the same species are not having any issues I would suspect flow. I've experienced similar issues and after all parameters checked out it turned out to be the flow. Once adjustments were made to the flow patterns the receding tissue stopped and grew back within the following week or two.

I had 1 acro that did this at the base when alk dropped below 7. It stopped once alk was back up. Pests are a high possibly too.
