Coral care

[Hp1836]

Does anyone know what's wrong when the top edges of a coral slowly start to wear away? Obviously the coral is not well. Im assuming it is either the wrong lighting or the wrong flow. Its it's happening with a space invader chalice and a bright green plating montipora frag. Testing everything is fine. All other 40+ pieces or coral are fine too

It could be low nutrients, high flow, or low flow, high lights or low lights... Pictures and parameters and details on the lighting and flow will help please

It could also be the maturity of the tank and the biome -- how established is the tank?

Really impossible without details as has already been stated. Pics too, preferably under whites, or at least with an orange filter

Pictures would greatly help
