RD. Posted August 27, 2005 Report Share Posted August 27, 2005 Ron - not a big concern unless you have very deep sand bads, with very fine grain sand (such as play sand), and fish that never dig. If it is still a concern, you can stir the sand up once a month or so by hand. Quote Link to comment Share on other sites More sharing options...
