"Saki-Hikari® R" offers a unique fusion of Saki-Hikari® benefits and new technology discovered at the Hikari® Aquatic Laboratory. Our "R Extract" provides koi keepers and breeders with another science-based option to keep their koi in top form.


For best results use Saki-Hikari® R when your water temperatures are consistently above 18C (64F). Remember the more active your koi are the more nutrition they require and lower water temperatures dictate less feeding. Nobody knows your koi better than you do, use the following as a guide and always avoid over-feeding. Never leave uneaten food in the pond after the feeding period.
Above 18C ( 64F)
Feed Saki-Hikari® R 2 to 4 times daily based on koi activity.
Below 18C ( 64F)
Carefully regulate the amount fed based on the activity level of your koi and your pond conditions. For colder weather feeding try Saki-Hikari® Multi Season™, with digestive characteristics which make it a superior choice for water temperatures that are consistently too cold to feed any other Saki-Hikari® diet.
To avoid reducing the benefits of the "R Extract", we recommend the Saki-Hikari® R is no less than 50% of the overall food fed. Using only Saki-Hikari® diets with a Saki-Hikari® R will offer the most synergistic effect of "R Extract" and "Hikari-Germ™".

We recommend Saki-Hikari R Balance as diet for
All championship grade koi or koi with championship potential.
