Bead filters are closed (pressure) vessels filled with thousands of plastic beads. These beads are very close together and form a layer through which the water is forced by a pump. As a result, the dirt particles stick in the beads. If the filters are used for some time, the biofilm (the sticky layer) around the beads becomes thicker, so that finer and finer dirt is caught.

Saki-Hikari Multi Season R (Small Pellet) – Premium Koi Diet
Protect your juvenile and smaller Koi during stressful seasonal temperature swings with Saki-Hikari Multi Season R. Younger Koi are especially vulnerable to health issues as water temperatures drop in the fall or fluctuate in the spring. Because their digestive systems naturally slow down in cooler weather, standard summer diets become too difficult to process. This highly digestible, wheat-germ-based formula provides complete, easily assimilated nutrition during these critical transition periods.
The revolutionary "R" series features the proprietary R-Extract—a powerful immunity-boosting blend that defends your vulnerable young fish against disease when cold water suppresses their natural defenses. Combined with the legendary Hikari-Germ™ probiotics, this small-pellet diet ensures your growing Koi maintain their health, body conformation, and vibrant colors through the colder months, preparing them for robust growth in the spring.
Key Features & Benefits
The "R-Extract" Immunity Boost: Enhanced with a proprietary blend of beneficial yeast and bacterial extracts. This unique additive supercharges your young Koi’s natural immune system, helping them fend off pathogens and parasites during high-stress temperature fluctuations.
Powered by Hikari-Germ™: Contains living, naturally occurring probiotics that promote maximum nutrient absorption in the gut. Better absorption means your Koi produce significantly less waste, keeping your pond water crystal clear and easing the biological load on your filters.
Cool-Water Digestibility: Built on a highly digestible wheat-germ base. You can safely feed your Koi this nutrient-dense formula even as water temperatures dip down to 50°F (10°C) without the risk of dangerous digestive blockages.
Maintains Bulk & Color: Standard winter diets often lead to faded colors and weight loss, which can stunt the growth of young fish. Multi Season R is packed with pure cultured spirulina and premium proteins to keep your juvenile Koi vibrant and healthy.
Small Pellet Size: The perfect bite-sized nutrition for young, growing Koi. These floating pellets (approx. 3.5–4.0 mm) are ideal for fish measuring up to 8 inches (20 cm), ensuring they can easily consume their food without struggling.

Feeding Guide
To maximize the health benefits of Saki-Hikari Multi Season R for your smaller Koi, adjust your feeding schedule based on your pond's water temperature:
Above 60°F (15°C): Feed 2 to 4 times daily based on the activity level of your Koi.
Between 50°F and 60°F (10°C – 15°C): Feed no more than 2 times daily. Feed only during the warmest part of the day when the fish are most active and likely to digest properly.
Below 50°F (10°C): Stop feeding entirely. The Koi's digestive system has largely shut down to prepare for winter dormancy.
Protect your growing Koi during seasonal temperature swings with Saki-Hikari Multi Season R. As water temperatures drop in the fall or fluctuate in the spring, a Koi's digestive system slows down, making standard summer diets dangerous to feed. This highly digestible, wheat-germ-based formula is specifically engineered to provide complete nutrition during these crucial transition periods and cooler weather.
