Technical Background

Vitamins are compounds required in minute concentrations for vital metabolic reactions; the amounts of vitamins required for a given species varies. Short-term vitamin deficiencies can typically be tolerated by most organisms, however long-term deficiencies tend to result in abnormalities, poor health, and eventually even death of the specimen. Conversely, if severely overdosed, ingested vitamins can have a negative impact on a specimen by way of toxicity, though the impact is unlikely to be permanent. Decreasing the vitamin dosage typically results in full recovery of the affected specimen. It is recommended that Vītamarin-F be utilized as a soak for vitamin-deficient foods, but not through direct addition to the water. Freshwater fish do not drink much water; rather, it enters their bodies as a result of osmotic pressure gradients. Resultantly, addition of Vītamarin-F directly to aquarium will be of extremely little benefit.

All Brightwell Aquatics liquid water care supplements are made with purified water and high purity materials. We develop formulae for aquaria based on empirical data, using observation and measurement rather than theory.

Vītamarin-F does not require refrigeration, however storage in a cool, shaded area will prolong the activity of the vitamins. Refrigeration will maximize the shelf-life of the product.

Instructions and Guidelines

To fortify food: Place food in a clean container such as a small bowl or cup and add only enough Vītamarin-F to saturate. Allow at least 5 minutes to elapse before feeding, enabling adequate time for the vitamins to become thoroughly absorbed by the food. Repeat with each feeding, or as deemed necessary by the general appearance of the organisms consuming the food.

When preparing fish for spawning, feeding frequency is often increased; limit the use of Vītamarin-F to twice each day. Apply same rule when feeding parents caring for young fish. Be sure to remove any uneaten food from the aquarium after 5 – 7 minutes to ensure that water quality is not negatively-impacted by excessive nutrient input. Avoiding overfeeding is a crucial aspect of successful aquarium husbandry.

Liquid food suspensions may be fortified by adding 1 ml (approximately 8 drops) Vītamarin-F per 10 ml of food suspension; stir to mix and allow 5 minutes to elapse before feeding.

Caution: Keep out of reach of children. Not for human consumption.
