Kills zebra and quagga mussels
EarthTec QZ is NSF-Certified to ANSI Standard 60 for drinking water, making it one of the most practical approaches available for controlling the spread and infestation of this devastating species. EarthTec QZ can be applied in lakes, reservoirs and pipelines leading to water treatment facilities. It disperses rapidly and is immediately bioavailable. Zebra mussels do not detect it as a threat and readily ingest it. Studies confirm complete mortality within a 48-96 hours. EarthTec QZ is also effective at concentrations that are non-toxic for most fish and other non-target organisms.
Copper 2+, the cupric ion
Thanks to its unique formulation, the copper in EarthTec and EarthTec QZ is kept entirely in the cupric ion form, the only biologically active form of copper. Therefore, it works at a significantly lower copper dose than copper sulfate or chelated copper products. There is virtually no waste or loss to precipitation or settling. EarthTec QZ is environmentally responsible copper for pest control.
