Was on a work trip for 2 nights and came back to see Setosa STN. Been in tank for 2 months with no issues and seemed to be doing well. Alk is 8, phos was up a little at .06 and nitrates up to 5. Would a slight nitrate/phosphate bump cause this? Also, I’ve been using some Vibrant for GHA. Should I dip the Setosa? Try and cut off white pieces?
