   The gobies certainly kick up some sand.  It is 100% caused by the gobies.  It is not that they directly kick up the sand, but they frequently deposit it directly in front of a CL outlet.  As soon as the outlet fires, it shoots sand into the water column.  
  There are good times and bad times.  I find it acceptable, but I'm sure other people would not.
