hi all, just changed my MH bulbs 3 days ago..realised tat a few of my acro's tips are turning white. so wat can i do to save it, or is it a goner??

anyway, did not upgrade my lights, just changed my old bulbs which were about 9 mths old. tks

Taking it that you are still using the same brand of bulb.

Your old bulbs would have weaken over the last 9 mths. So your acros and corals have gotten used to your weakened intensity of light.

When you reintroduce a new bulb...you would need to reaclimatise your corals to it again or there's a possibility of them getting shocked. IMO, the bleaching of your acros could be due to this problem.

so.. should i do it now or are they goners? any chance of them recovering?

Raise the height betw ur MH and ur tank. Slowly lower the MH every wk over a period of 4wks.

The bleached tip is ok as long they r no subject to further stress leadin to RTN. It will take some time for the color to come back again.

Cutting short your photoperiod for now would help too.
