Aquarium accessories Flourish Nitrogen

Eliminates ectoparasites and fungal, bacterial and viral lesions. Safe dosage. ParaGuard is the only aldehyde-based pest control product that is safe for fish and filter (for fish parasites). Unlike formaldehyde-based drugs, which are highly toxic and difficult to use. Contains no formaldehyde or methanol and does not alter pH. ParaGuard uses a proprietary synergistic blend of aldehydes, malachite green and fish-protecting polymers to effectively eradicate many ectoparasites. It also treats external fungal/bacterial/viral lesions (e.g. fin rot). Particularly useful in quarantine. 100 ml treats 100 l.
