Fritz Coppersafe® solution remains active for over one month in the aquarium. It is a safe, stable, non-staining concentrate that does not color aquarium water.

Be sure to add Fritz Coppersafe® solution to replacement water when water changes are made. This will maintain the therapeutic level of Coppersafe® solution.

Because Fritz Coppersafe® solution is so stable in water, partial water changes are the quickest way to remove it from the water.

The unique formulation of Fritz Coppersafe® solution maintains a total copper level of  ~2.0ppm when used as directed. Copper test kits that measure chelated copper will help you to actively monitor copper levels when using Fritz Coppersafe® solution.
