Product details
Seachem ParaGuard 500mL (603) is an aldehyde-based parasite control medication designed for fish, including treatment in hospital and receiving tanks. It’s used to help eradicate common external parasites and certain external lesions on fish (for example, ich/white spot and external fungal/bacterial/viral lesions), supporting safer treatment when you’re managing newly introduced fish or isolating a problem in a community system. It is formulated to be compatible with aquarium filtration so it can be used without disrupting the bio-filter.
Features:
- Aldehyde-based parasite control (10% by weight) for fish affected by external parasites
- Targets many ectoparasites, including ich (white spot) and velvet (as commonly listed indications)
- Also helps with external fungal/bacterial/viral lesions such as fin rot
- Includes a synergistic blend of aldehydes, malachite green, and fish protective polymers
- Aims to be safer to dose than formaldehyde- and formalin-based alternatives (per the manufacturer’s comparison)
- Stated not to contain formaldehyde or methanol
- Stated to not alter pH and not adversely affect the bio-filter
Specifications:
- Product size: 500 mL (603)
