Product Details

sera (Sera) Siporax Professional Large Granule Type (25mm) Used.

● Ring Size: Diameter 25mm x Height 25mm (actual measurement)
● Case Internal Dimensions: Filled to capacity in a 430mm x 430mm x 200mm case
● Volume: Approximately 26L (due to the large granule type with many gaps)

This is a high-performance glass ring filter medium, weighing approximately **290g per liter**, with a very large surface area for nitrifying bacteria to colonize, making it excellent for biological filtration.
This is an optimal amount, especially for those using **large overflow aquariums** or **large external filters**.

The bacteria are already established, so you can wash them and use them immediately.
Suitable for both freshwater and saltwater.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
