this is a tank I put together back in 2013 I made the mistake of tearing it down I miss it , as it was one of my better macro tanks everything thrived ,
I believe you got your rock from the same place I did , I had all kinds of goodies even a few nice lps
corals , every thing made it through the cycle just fine high nitrates and phosphates will effect how the coral and macros look but they will recover once you get things right
be sure you check your test kit you may have a bad bottle of regent that causes false readings . I recently had that issue with a bottle of regent my nirates were a 0ppm but my phosphates were over 10ppm , I knew this wasn't right as I did over 200g of water changes in a week , I was removing all my sand and replaced with new .
I borrowed a test kit from a friend found my reading was off by a long shot actually had ,25 ppm
nothing to stress about . that's about normal for all my tanks
