ParaGuard™ is the only fish and filter safe aldehyde based (10% by weight) parasite control product available (for parasites on fish). Unlike highly toxic and difficult to use formalin based medications, ParaGuard™ contains no formaldehyde or methanol and will not alter pH. ParaGuard™ employs a proprietary, synergistic blend of aldehydes, malachite green, and fish protective polymers that effectively and efficiently eradicates many ectoparasites (e.g. ich, etc.) and external fungal/bacterial/viral lesions (e.g., fin rot). It is particularly useful in hospital and receiving tanks for new fish and whenever new fish are introduced to a community tank.

Dosing

Remove all invertebrates from the tank as well as any chemical filtration. Use 5 mL (1 capful) of ParaGuard™ for every 40 L (10 US gallons). Repeat this dose daily as required as long as fish show no stress.

ParaGuard™ can also be used as a medicated dip. For 1 hour dips, use 3 mL per 4 L (1 US gallon) in a container separate from your main tank. Dips may be extended if the fish show no evidence of stress. Keep in mind that many diseases linger in the water as well as on the fish. Giving a fish a dip treatment does no good if they go right back into infected water.

Quarantine

This is a tank set up in order monitor and medicate new fish before they go into the main tank. ParaGuard™ is gentle enough to use prophylactically (without visible symptoms) if needed. Quarantine times vary, but we generally recommend 2 weeks of treatment with ParaGuard™ to clear out any possible external infections.
