Inverts can't handle any medication or copper so if you ever treat the qt you will kill them. I would setup a tiny invert only qt. 1-2 pts a day is fine but spread out, not all at one time per day
I wont be treating the qt with hypo or copper since the hippo tang I have there looks clear of any parasite, just got him yesterday and will observe for a couple of weeks. The salinity in the DT is at 1.025 and will lower to 1.023 tonight.
What would be my target for hyposalinity, what number?
