  • Unique complex that provides trace and minor elements in ration found to be beneficial to rainbow fish and other fishes that share the same waters of origin.
  • Provides minor and trace elements utilized in important neurological and metabolic reactions, and which are incorporated into natural biopigments for coloration.
  • Replaces minor and trace elements used by aquarium inhabitants, and lost throught chemical filtration (use by filtration media such as resins and activated carbon)
  • Composed of purified water and ultra-high purity materials. Does not significantly increase GH or KH.
  • Formulated utilizing extensive research on chemistry of the waters naturally-inhabited by rainbow fishes and blue-eyes, as well as their trace and minor element requirements.


Technical Overview:

The role that trace and minor elements play with rainbow fishes and other fishes is related to neurological and metabolic processes (in which these elements play critical roles), as well as overall coloration (trace and minor elements are often at the core of pigments know to enhance coloration); of these aspect, it is coloration that is often most important to the rainbow fish enthusiast, as few experienced hobbyists will deny that male rainbow fish displaying to a female are some of the most brilliantly-colored fishes maintained in captivity. Dosing a trace and minor supplement with every water change performed is an effective method of delivering these substances for maximum benefit.
Rainbow fish and their allies, the Blue-eyes, are native to all manner of water bodies throughout New Guinea and parts of Australia. Water chemistry in these system varies from moderately-acidic to alkaline, and extremely-soft to-hard, while it is generally unnecessary to maintain water parameters for a given species exactly like those of their native habitat, it’s sensible to approximate these parameters for long term health of the fish.
That stated the majority of rainbow fishes (with few exceptions) adapt well to a general hardness of 9 12 dGH (150-200 ppm) and pH of 6,5-7,5 though some may require harder or softer conditions (blue-eyes inhabit coastal environments and do well in varying degrees of brackish water; for other species requirements consult a reputable text). Maintaining immeasurable ammonia and nitrite and <20 ppm nitrate, is more important than attaining specific pH and dGH values for long-term health of rainbow fishes.
A number of popular ornamental fish species such as various gudgeons, gobys and scats are often found in the same waters in which rainbow fishes and blue-eyes originate; hence RainbōwCōde may also be used in aquaria housing these fishes with equal success.

Instructions and Guidelines:

Shake product well before using.
Community Rainbow fish Aquaria: add ½ ml (10 drops) of product per 25 gallons of aquarium water every other day. When used in this fashion, 250 ml treats up to 2500 US-gallons.
Biotope aquaria: as noted opposite, the water conditions that rainbow fishes and blue-eyes originate from in the wild is wide-ranging. It is therefore sensible to use different dosages of this product for biotope aquaria in which fishes with different requirements are housed. Use the following dosages as a general guideline for each biotope aquarium and increase or decrease dosage as deemed necessary by the appearance of the inhabitants and overall aquarium.

Rainbow fishes endemic to acidic pH habitats: add ¼ ml (5 drops) of product per 25 gallons of aquarium water every other day.
Rainbow fishes endemic to alkaline pH habitats: add ½ ml (10 drops) of product per 25 gallons of aquarium water every other day.
Blue-eyes: Add ¾ ml(-15 drops) of product per 25 US-gallons of aquarium water every other day.

Note that starting out at a dosage of ½ those recommended above and then gradually increasing the dosage over a period of weeks is often a good practice to follow in aquaria that have not received any previous trace and minor element supplementation; doing so 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. Though trace and minor elements are essential to critical biological processes, their gross overdosing 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 slighty heavier dosing of this product to compensate for that which is bound. Note that activated carbon will remove trace and minor elements both passively and actively.

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