Feed once daily the amount your turtle will consume within a few minutes. In lower water temperatures less food is required. Saki-Hikari® Turtle is most effective when used exclusively and without interruption as a daily diet. The Hikari Germ™ is a transitory bacteria that does not remain in the intestine and is quickly discharged once feeding is discontinued. Intermittent use or mixing with other diets will not allow the Hikari Germ™ to offer its maximum benefit.
