A complete vitamin supplement with natural lipids and aminos. It`s great for fin regeneration & preventing lateral line disease. Highest amount of active vitamin C available. 4oz. Vita-chem for fresh water fish and Vita-chem for marine fish is an extraordinary new fish vitamin introduced by Boyd Enterprises, Inc., manufacturers of the world famous Chemi-pure. All other fish vitamins on the market use a timeworm approach, adapt an already existing product such as vitamin bases available to the Veterinary profession and put a fish product label on them. This method works to a degree, but to a nominal extent. The aquatic and marine animals and fishes require specialized naturally occurring substances and chemicals and amino acids and lipids to be effectively utilized by their specialized bodily processes. Vita-chem marine and Vita-chem fresh is a totally new concept in aquatic and marine vitamin formulation and methodology that is - give the animals and fishes exactly what they are missing from their natural habitat and environment in a compact concentrated and easily assimilated solution compatible with their individually specialized systems and environments. After many years of research by the noted marine life researcher, Mr. John Nobles, in conjunction with Boyd Enterprises, Inc. and a hi tech think tank composed of numerous marine and aquatic biologists and at least ten years of experimentation with thousands of specimens under actual hobbyist conditions - Boyd Enterprises, Inc. is marketing the most effective concentrated environmental vitamin ever to be offered to the aquarium trade. Actually reverses and cures Lateral Line Disease (which is not actually a disease, but an ecologically induced condition).
