Safe Medication for Fish
Seachem ParaGuard works as a fish medication that eliminates ectoparasites, fungal, bacterial and viral lesions, all of which affect the development of fish.
It is safe for fish and bio filters, and does not pose any danger to your aquarium as compared to traditional methods of dosing formaldehyde, formalin, and methanol.
Suggested Treatment Period
ParaGuard is effectively for treating the following diseases:
|Disease||Suggested Treatment Period|
|Ich (White Spot)||14 days in freshwater, up to 28 days in saltwater|
|Fin Rot||7 days or until infection clears|
|Flukes (Gill and Body)||14 days or until infection clears|
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.
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.
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.
Some fish are more sensitive to medications than others. Eels, loaches, rays, sharks, and many others are well known for their sensitivity to all kinds of medications. If you suspect that your fish may be sensitive to medications, it is just fine to start with a partial dose and build up to the full dose over several days.
Not recommended for reef aquaria. As an alternative, use Seachem MetroPlex.
1. Is ParaGuard safe for use in marine reef tanks with invertebrates and soft corals?
Answer: 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 invertebrates 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.
2. Is there copper in ParaGuard?
Answer: No, there is no copper in ParaGuard
3. Is it safe to use ParaGuard in planted aquarium? Can my plants survive?
Answer: 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.
4. Do I need to remove Purigen from my filter while medicating with ParaGuard?
Answer: While the primary active ingredient in ParaGuard is unaffected by the presence of Purigen, the malachite green does have potential to be removed by the media. Since the product is most effective when both of these components are present to perform synergistically, we do recommend that the Purigen (as well as any other chemical filtration media) be removed while treating. If removal of waste is of primary concern in the treatment tank, then Purigen may be left in place, but the medication will not be as effective.
5. Is ParaGuard safe for Loaches or scaleless fish?
Answer: You can use any of our medications with scaleless fish, but as they can be more sensitive, we would recommend that you begin with a 1/4 to 1/2 dose first and slowly build to the recommended dosage.
