Seachem Paraguard 100ml
	ParaGuard™ Support 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 save 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.
