[Nicolas Dumetz]

Hi Everybody,
I move one of my tank into one of my other tank on january 1 everything was fine and its been a week now that a see couple of my acro tips are like disappearing or eat by something. Do you have any idea what it would be? My parameter are alk 7 ca 420 mg 1350 no3 5ppm po4 0.03 .
Thank you

Still hard to tell from those photo's. If tips are actually getting shorter?... I would double check for alk swings, watch the tangs to see if they are nipping, I have had a yellow tang nip when not enough algae was present to nibble on. If tips are "busted open" then i would look at verifying params with other test kits, especially alk. If tips are getting longer but white?.... it's growth.
