Bleached acros...

[EvilE]

All my softies are thriving fine, but my acro frag is now bleaching--is it dieing? Why is this happening? I feed my corals Phytofeast every day, and like I said alls happy except my acro. Is the lighting not strong enough? I have a 30 gallon with Coralife PC's 50/50 bulbs.

Could be a number of things, Nitrates, alk, pH, Mg, Salinity fluctuations phosphate, temp, or something might not be balanced in that category or fluctuating. Lighting is also possible, do you know the lighting from which they came and how long have you had the the acros. Softies are a little more forgiving.

If the stress-causing bleaching is not too severe and if it decreases in time, the affected corals usually regain their symbiotic algae within several weeks or a few months. If zooxanthellae loss is prolonged, i.e. if the stress continues and depleted zooxanthellae populations do not recover, the coral host eventually dies
