REEF GEL® Veterinary Diets are designed for use with fish and aquatic invertebrates including tropical and coldwater species. The diets are designed for use in medical treatment regimes and in the routine preventive medicine management of stock during acclimation into new environments including quarantine and displays. The diets contain the immunomodulator complex IMUFIN® and optimised vitamin, antioxidant and lipid classes. The Professional Twin Pack would allow a veterinary surgeon to distribute active medicines such as antibiotics or anti-parasitic products into the dry phase before the addition of the supplied PLANKTONIC™ lipids and antioxidants. Following the period of application REEF GEL® Daily Use Diet should be used for long term maintenance where appropriate for the species.
