Sera Toxivec 100ml

It also removes aggressive chlorine from tap water. It is also effective against residues of used disinfectants or remedies. Sera Toxivec can do even more: It also reliably binds toxic heavy metals such as copper, zinc, lead or even mercury. Thus, these pollutants can no longer be dangerous to the fish or the useful bacteria in the biofilter. The number of water changes is thus reduced. If required, i.e. in case of particularly high load values, Sera Toxivec offers the possibility of a higher dosage without any problems. A second application after one to two hours is also possible.
