Pond Boss Forums MANAGING AN EXISTING POND Fertilization will fertlizer help clear a pond

Your banks must not be all sand if you have clay turbidity. Sand is too heavy to suspend.

Fertilizer will help promote a plankton bloom, however, you need light and if light penetration is retarded by suspended solids you will not get a bloom.

Gypsum and aluminum sulfate are cheap ways to get rid of turbidity, but I would recommend the gypsum first, for alum will decrease your alkalinity.
