There is a New Life Spectrum® formula for almost every freshwater fish, marine fish, crustacean or coral in your aquarium. The Spectrum family of formulas all feature high-density, quality nutrition from natural ingredients. We have been proven right. Spectrum has grown since it’s introduction with only minimal advertising — through great word-of-mouth on it’s quality and effectiveness. This grassroots growth is only possible by putting out an extraordinary product. We create an exceptional product by putting a lion’s share of our revenues into ingredients rather than marketing.
