Its a type of tree oil and an astrigent. I've been told its a good remedy for tanks with inverts (will not effect). Simply add to water and remove carbon. Its also supposed to be good for cuts and injuries other fish may have.
That's what I thought, but the owner of the local fish store swears it will cure it.

Here is the product description from the website, maybe the "prevents the development of resistant strains of disease-causing organisms" is the key?
Treats cotton-like fungal infections, and both internal and external bacterial infections. PimaFix harnesses the unique antifungal and antibacterial properties of the West Indian Bay Tree (Pimenta racemosa) for a safe and natural remedy; prevents the development of resistant strains of disease-causing organisms. Will not discolor water, affect biological filter, or pH during treatment. Will not harm aquatic plants. For extreme cases, PimaFix can safely be used with MelaFix to provide the added benefit of quick tissue regeneration and wound healing. 8 oz doses 400 gallons.
Contains the natural botanical extract from the Tea Tree (Melaleuca), an excellent alternative to resistant strains of bacteria that are unaffected by traditional medications. Treats bacterial infections such as red ulcers, fin and tail rot, cloudy eyes, mouth fungus, and others in as little as 4 days. Also heals open wounds, ulcers, and damaged fins. Doesn't affect pH; safe for invertebrates. NEW MelaFix Marine can also be used with corals to control bacterial infections, reverse coral degradation and remove parasitic flatworms. 8 oz treats 480 gallons of marine or freshwater. 64 oz is a concentrated formula and treats 19,000 gallons. 8 oz MelaFix Marine treats 474 gallons marine water.
I have used both before. They are very mild and don't do too much. They will certainly not do anything for ich. If you do not have a cycled QT then you may want to consider setting up a rubber maid tub for your LR and inverts. You can then perform Hyposalinity on the display.
