Description Trace & Minor Elements for Rainbow Fishes, Blue-Eyes & other Tropic Fishes of Australia & New Guinea. Unique complex that provides trace and minor elements in ratios found to be beneficial to rainbowfish and other fishes that share the same waters of origin. Provides minor and trace elements utilized in important neurological reactions, metabolic reactions, and improve coloration. Replaces minor and trace elements which are lost through chemical filtration. Does not significantly increase GH or KH. Made in the USA. RainboCode Instructions Trace & Minor Elements for Rainbow Fishes, Blue-Eyes & other Tropic Fishes of Australia & New Guinea Overview Unique complex that provides trace and minor elements in ratios found to be beneficial to rainbowfish and other fishes that share the same waters of origin. Provides minor and trace elements utilized in important neurological and metabolicreactions, and which are incorporated into natural biopigments for coloration. Replaces minor and trace elements used by aquarium inhabitants, and which are lost through chemical filtration (use of 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 byrainbowfishes and blue-eyes, as well as their trace and minor element requirements. Technical Background The role that trace and minor elements play with rainbowfishes 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 known to enhance coloration); of these aspects, it is coloration that is often most important to the rainbowfish enthusiast, as few experienced hobbyists will deny that male rainbowfish 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. Rainbowfishes 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 systems 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 (e.g. moderately-hard water and alkaline pH for species native to habitats featuring these conditions, and vice versa for fishes hailing from soft-water, acidic waters) for long-term health of the fish. That stated, the majority of rainbowfishes (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).
