I've had my nano up for over a month now and my clove polyps were doing ok, but are now basically dead, many of my zoo's have been closed for most of this week, and my plate coral is not doing too well. All my levels are where the should be, anyone have any idea why stuff is not doing to great. I made a mini skimmer that has been working great, but is it true it may be removing too many nutrients? How do you tell if stuff is starved, or if I'm over feeding? Thanks
