White patches on birdsnest coral

[ianmphua]

Hi all, recently i’m starting to see some white patches on my pink birdsnest coral. These patches don’t seem to have any poylps on them. Could this be due to excessive light?

It could be many reasons.

Lights - best to measure PAR to know if its too high/low.

Trace elements - possible if any are zero for extended periods of time and affecting cell function. Definitive way to know is to send for ICP test. Then dose trace elements accordingly. If not willing to spend this $$, just do very very major water change to refresh to new water.

Other water parameters - Ca, Mg, Kh, K, pH, NO3, PO4 are some things you can measure with home test kits.

I have a feeling it may be high light because the areas of birdsnest which are more shaded are still pink and have good polyp extension. Will try to turn down the lights a little. Thanks for your reply!
