Saki Hikari

Waste reduction is visually apparent using Saki-Hikari!

The rapid, bacterial decomposition of the koi's waste caused by the "Hikari Germ" drastically reduces buildup in the filter media thereby reducing the frequency of regularly scheduled maintenance. Overall improvement of the water clarity and condition are side benefits of this process.

After thoroughly rinsing the filter media and precipitating out the collected sludge, the volume of raw waste collected in each of the test filters was measured. Test results showed the tank fed Saki-Hikari contained almost half the waste of the tank fed common koi food.
