Acro symptom question

[kmacartney]

Hi,

I have two identical acro colonies and they both experienced "burnt" looking tips before starting to RTN. Does anyone have any suggestions about what might cause this. The only water parameter that I found to be off was that my salinity was around 1.028.

Thanks,

Keith

did you replace the lights? what other parameters did u check?

Are they new? Did you add anything to the tank lately? Did someone spray the room down with air freshener? What are your phosphate and nitrate levels?

The are 3 year old colonies. I have only recently started to add Brightwell 2-part . No chemical either. Phosphate and Nitrate are undetectable via API. My other coral have really started to color up.
