about five or six weeks ago water was so cloudy one could not see white stones in shallow part , about 8'' deep . finally cleared that up after about ten days and water became the usual CRYSTAL CLEAR . about two weeks ago water clouded up again not as badly but it has stayed that way in spite of my attempts to clear it . frustrating thing is that this is first year we have left our heron repelling net off and end up with the unpleasant water . by the way , we had 17 fish when it clouded first time and when it cleared we had ten . i hope i'm alone with lousy water quality because it is annoying . . . .peace . . . ps . we used to be on '' pond forum'' but it has disappeared , so here i am .
