However I will try placing it lower and see if it helps.

Hi,

Any Acropora can burn if its placed under lighting thats its not used to. Did you recently add the frag? If so it's best to place it on the bottom for a few days first and then gradually raise it to the desired position. I have burn't acro's before under T5's the PAR can be surprisingly high.. On another note, the tip burn might be from a parameter & not the lighting? Such as Potassium or Alk/Dkh Swing.

BTW if the tissues starts receding, it would be best to clip the affected area off.

Hope this helps.

Simon.
