The patented time-release system is designed to deliver a proprietary blend of natural bacteria and enzymes into the water continuously, over a 15-day period, to consume excess nutrients and eliminate odor. Water may take on a cloudy appearance for the first few days, while bacteria begin to work. Every water feature is different and correcting water problems, naturally, occurs with time and continued use, therefore results may vary. This easy to use product is safe for fish, plants, birds, animals, pets or people.
