Base Layer Media: Improves flow distribution and prevents material migration.

In multi-layer sand filters pea metal serves as the bottom layer, providing structural support and improving flow distribution. It ensures even water flow throughout the system and prevents the migration of finer particles into the drainage system during filtration or backwashing. Note: Garnet is approximately 25% heavier than Pea Metal and has the ability to maintain performance under higher-than-normal pressure conditions.
