Trace & Minor Elements for Discus & other South American Riverine Fishes

  • Unique complex that provides trace and minor elements in beneficial ratios
  • Supports neurological and metabolic reactions
  • Improves coloration
  • Replaces minor and trace elements lost through chemical filtration
  • Made from ultra-high purity materials and purified water
  • Formulated using extensive research on the chemistry of waters naturally-inhabited by discus and discus requirements

Discus are native to many of the quiet waters of the Amazon River basin, primarily inhabiting pools, small creeks, and streams of (primarily) blackwater habitats. These ecosystems contain unique water chemistry with specific ratios of trace and minor elements that play important roles in the health and behavior of discus, cardinal tetras, angelfishes, festivums, uaru, and other fishes native to the region. The trace and minor elements are involved in crucial neurological and metabolic processes and contribute to the fishes' overall coloration. Brightwell's DiscusCode provides a unique complex of these elements in the right ratios, and adding it to your tank during each water change is an effective way to provide these substances for maximum benefit.


Instructions & Guidelines

Basic: Shake product well before using. Add per the directions on the bottle.  500 ml treats up to 2,000 US-gallons (7,600 L). This dosage may also be used for freshwater community aquaria.

Advanced: With the exception of iron, there are no hobbyist-grade test kits that provide reliable measurements of the concentrations of many minor and trace elements present in freshwater aquaria. It's therefore not possible to chemically determine exactly how much of a trace and minor element supplement to dose; rather, you must rely on the appearance of the livestock to make that determination. Follow the directions on the bottle. Gradually increase the weekly dosage per the directions over the following four weeks and maintain this dosage. Starting at a low dosage will not cause any harm to aquarium inhabitants, and will enable you to notice subtle changes in the appearance of the system that indicate the effectiveness and need for the product. Daily dosing maintains more stable concentrations (and a more natural environment) than dosing weekly, in which the concentration of elements spikes just after dosing and then gradually decreases throughout the course of the week. Though trace and minor elements are essential to critical biological processes, the gross overdosing of a trace and minor element supplement can be harmful to aquarium inhabitants. Minor and trace elements are made unavailable in aquaria largely by adsorption to particulate organic matter (POM); therefore, aquaria with large amounts of latent organic material may require slightly heavier dosing of this product to compensate for that which is bound. In all cases, latent organic material should be removed as thoroughly as possible from aquaria because of the negative impact that it can have on water quality. The use of activated carbon will remove trace and minor elements both passively and actively, requiring that this product be dosed after the use of carbon filtration media.


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


Ingredients: Purified water, species specific minor and trace mineral blend
