Cloudy, discolored water is caused by overfeeding, biological blooms, gravel dust and other suspended particles that are too fine to be removed by mechanical filtration and stay in the water column. Fritz Clarifier rapidly clears water by pulling together (flocculating) fine particles, allowing them to be removed by the filter or settle to the bottom, leaving your aquarium crystal clear
Use 1 tsp (5 ml) per 10 U.S. gallons (38 L). Water will clear rapidly. Repeat as needed, allowing 6 hours between doses
