We are healed by watching aquatic plants and swinging green in the water.
But maintaining those greens in the aquarium tank is not easy. Potassium is always in shortage in the aquarium while nitrogen, and phosphate are oversupplied in right formula by human hand.

Through daily nutrient supply, and aquatic plant maintenance, we understand how complex, delicate, and elaborate our Mother Nature is.
At the same time, aquatic plants "Green" tells us we do not live by ourselves, but our life was supported by the Green.

Desalinated deep seawater is used as a base of Green Brighty series. It promotes nutrient absorption of aquatic plants, and has an effect of developing good leaf coloration.

Additives series, used for keeping aquarium environment, are contained in an eye drop container, which is easy to supply a small amount in the aquarium. Like liquid fertilizer series, economical large volume bottles are also available for refill.
