Blagdon Clear Pond clears dirty cloudy water and aids filtration, making murky ponds attractive and allowing for viewing of fish. Suspended particles can negatively affect fish and plant health by clogging gill membranes and reducing light penetration. This treatment rapidly clumps suspended particles, causing them to settle out of suspension or be trapped in the filter, thus increasing the effectiveness of mechanical filters. It treats up to 22,750 liters of water and is easy to use with clear instructions and a dosage chamber for accurate application.
