Be aware that when doing many comparisons the risk of a false-positive result increases.
In this case, there are 29 comparisons, you can thus expect the following amount of false-positive results:
  1.45 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.29 false positives, when considering a   1% risk acceptance (**, ***),
  0.03 false positives, when considering a 0.1% risk acceptance (***)
