ParaGuard is the only fish and filter safe aldehyde based (10% by weight) parasite control product available. 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.
DIRECTIONS: In the aquarium, use 5 mL (1 capful) to every 40 L (10 gallons*). Repeat daily as required as long as fish show no stress. For 1 hour dips, use 3 mL per 4 L (1 gallon*). Dips may be extended if fish show no evidence of stress.
In case of eye exposure, promptly and thoroughly wash eyes with water: seek medical attention.
FAQ from Seachem
Q: How do you maintain 12 ppm aldehyde?
A: Treat for 2 days, then skip a day, then treat for 2 days again. This should keep you in the 12 ppm range.
Q: Is ParaGuard safe for use in marine reef tanks with invertebrates and soft corals?
A: We do not sell or market ParaGuard as invert safe because it would be impossible to test it with every available invert under every potential water parameter. We have had people use it with invertabrates with no problems, but we have also had people encounter problems. If you decide to use it we stress caution; dose at 1/4 to 1/2 dose and observe how your inverts and soft corals react. If they seem to tolerate the dosing, increase slowly up to no more than the prescribed dose as long as they are tolerating it. If you need to get rid of the ParaGuard quickly, just turn your skimmer back on.
Q: I was wondering if there was copper in Paraguard. I have a few hermit crabs in the tank, that I would prefer not to kill, and removing the affected fish is not an option in this case.
A: No, there is no copper in ParaGuard
Q: Is it safe to use ParaGuard in a planted aquarium? Can my plants survive?
A: We do not sell or market ParaGuard as invert/plant safe because it would be impossible to test it with every available invert/plant under every potential water parameter. It has been my personal experience that it is generally safe to use in planted aquaria and would not hesitate to do so.
