Description
xOverview
Seachem ParaGuard is a 10% by weight aldehyde-based parasite-control formulation designed to help address external parasites and surface lesions on fish. It blends a safe aldehyde approach with malachite green and fish-protective polymers, and it contains no formaldehyde or methanol. The formula is pH-neutral, which helps preserve water chemistry in your tank—useful for both freshwater and marine setups.
The product takes a multi-pronged approach to common fish health issues, focusing on surface-dwelling problems that can appear as white spots, fin damage, or other visible signs of stress. ParaGuard is particularly valued in hospital or quarantine tanks and during new fish introductions, offering a way to support health without disrupting established tank chemistry.
