Parashield®, with its revolutionary bio-adhesive supplement, repairs and strengthens the essential slime coat of fish, guarding them from Ick, Velvet, and other parasites. An amalgam of natural oils and extracts, coupled with a proprietary film-forming matrix, fortify your fish's slime coat and represent a reliable barrier against bacterial and fungal infections. Note carefully: do not exceed the recommended dosage. Temporarily, there may be reduction in the activity of certain sessile invertebrates for up to 24 hours after application. Parashield® has been tested on Stone Polyp, Brain Favites, Mushroom (Rhodactis), Ricordea Sp., Favia Fragum, Plate Coral Sp., Tubastraea Sp., Knobby Leather Sp., Acropora Sp., and Finger Coral (Porites) species - however, all corals and polyps may not respond in the same manner.
