BASSLEER BIOFISH FOOD FORTE is a nutritionally designed, fitness-enhancing food for ornamental freshwater and marine fish, providing high-quality nutrition and immune support and also suitable for fish diseases, particularly during periods of stress, disease-prone periods, or as a regular health supplement. Forte is prescribed every 3-4 weeks, according to official information, as a fitness treatment to support long-term health and resilience.
KEY BENEFIT
1. Strong health immune stimulants: Forte has added immune supportive ingredients – vitamins, trace elements, and probably probiotic or bioactive additives – to enhance fish resilience, disease resistance, and overall vitality.
2. Complete premium nutrition: Forte has the same nutritional basis as the “Regular” feed; it provides essential protein for growth, essential amino acids, healthy fats, vitamins, minerals, and trace elements to support metabolism, organ function, and overall health.
3. Universal Fresh and Marine Water fish feed: The feed applies to a wide variety of decorative fish species and aquarium systems – fresh or salty, small or big community tanks or systems.
4. Regular “Health Reset” through Feeding Cycle: According to the manufacturer’s recommendations, with Forte every 3-4 weeks, it is recommended to refresh the fish in the environment or during seasons of stress, which improves their immune system and vitality, as well as prepares them to face environmental or seasonal challenges.
5. Soft on Water and Easy to Digest: Using Dr. Gerald Bassleer’s smooth soft production method (low-temperature pellet formation, followed by post-production coating with additives), Forte is easy to digest and preserves vitamins and trace elements, with minimal waste and low water contamination.
WHY & WHEN TO USE
1. A regular health check feed: Every 3-4 weeks, change to Forte 7-10 days to strengthen immunity and overall health, and then back to regular feeding. This is to prevent seasonal or environmental stress.
2. During or after stress events: Following transport, water changes, tank cleaning, the introduction of new fish – times when fish are more susceptible – Forte assists them to adapt.
3. In disease-prone or crowded tanks: Aquariums with high stocking density and frequent stressful events should undergo periodic immune stimulation and nutritional resets.
4. To breed or display fish: When preparing fish for breeding, display, or sale, it is vital to ensure the fish is in optimal health and has the highest immunity by improving vitality, color, fertility, and overall condition.
5. As a feeding rotation program: Alternate between regular and specialized feeds (such as Chlorella, Green Fuco) and Forte now and then as an additional source of consistent nutrition and a periodic boost.
