ParaGuard

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 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.

Q: Do I need to remove Purigen from my filter while medicating with ParaGuard?

A: 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.
