So I’m very, very new in my sps journey. I’ve be been keeping some acros for almost a yr now and had a couple hiccups along the way but nothing major…. Till Friday. I’ve had this TSA cherry bomb for about 6 months and it’s been great, encrusting out, putting a bit of growth upward. Then I noticed a white patch in the side friday evening, two days later I noticed all the tips of the colony had lost color, still have the polyp, but noticeably less color(almost white). Is this the start of STN? I just sent out a ICP test the day before I noticed the issue so I should have those in a couple days but what is do have is: alk-8.2dkh, mag-1300ppm, cal-350ppm, phos-0ppm, nitrate-10ppm. Any ideas are greatly appreciated as this is unfamiliar to me.
