Ok, read this more carefully. I do think your problem was the purple up (possibly some of the other additives as well). I don't think it is copper, and hobby copper test kits have terrible resolution.
Purple up is powered aragonite which according to Randy Holmes-Farley will not dissolve in seawater (counter intuitive I know), but will show a false calcium bump. Its like adding finely crushed/powered sand to your tank that can coat and stick to everything - including animals. Its seems also to be a case of 'it happened after, so it was caused by' meaning people claim to get coralline algae after adding purple up, however people who don't add purple up get coralline just as quickly as people who add purple up.
I would do two 50-90% water changes with either water from another tank (because your tank isn't that huge) or water that has been mixing and heating and aerating for 24 hours. I would also stop adding any additives as I think they are just going to stress compromised animals more (and besides Ca, Mg and Kalk I don't think they really do much good). Add the poly filter if you want to - they don't release anything into the water.
Good luck!
