Fritz Clarifier Professional Water Clarifier

Clumps Together Suspended Particles That Affect Clarity
Improves Filter Efficiency
For Fresh and Saltwater Systems, Plant and Reef Safe
Phosphate Free
Made in the USA

Cloudy, discolored water is often caused by overfeeding, biological blooms, gravel dust, and other fine suspended particles that slip through mechanical filtration and remain in the water column. This advanced clarifier rapidly clears water by pulling together (flocculating) these tiny particles, allowing them to be removed by the filter or settle to the bottom—leaving your aquarium crystal clear.

This formula will not affect bio-filtration, pH, or other important water parameters like other brands. Safe and effective for freshwater, saltwater, reef aquariums, and ponds. 100% phosphate free: safe for all fish, plants, and invertebrates, and will not contribute to future cloudy water problems.

Use 1 tsp (5 ml) per 10 U.S. gallons (38 L).
Water will clear rapidly.
Repeat as needed, allowing 6 hours between doses.
