Product review (5 stars): WATER CLARIFIER
I used many other such items....but none does the job as this one does,...no more green water, only crystal clear water  with stuff at the bottom  which with brushing and filter system it all goes away...AT TOP LEVEL ITEM AND DOES THE JOB IN MY 24 BY 14  FT.  POND...CVERY HAPPY WITH THIS,,,,,,,,,,,,,,JAMES
