Gravel & Silica sand

Sand and Silica Gravel Characteristics

The characteristics of silica sand and silica gravel used in swimming pool filtration systems are detailed below

Silica sand

• It is made up of small silica particles that are processed for use in sand filters.
• It has a smooth and uniform surface that allows for uniform water flow and greater filtration efficiency.
• It is resistant to temperature changes and chemicals used in pool systems.
• It is durable and can last several years before requiring replacement.
• It is recommended to change the silica sand once a year or every two years to maintain the effectiveness of the filter.

Silicic gravel

• It is composed of silica stones larger than silica sand.
• It is more porous than silica sand, meaning it can trap larger particles at the bottom of the filter.
• Helps prevent compaction of silica sand in the filter.
• Increases the durability of the filter and protects against abrasion from silica sand.
• It is a durable filter media and can last several years before requiring replacement.
• It is recommended to change the silica gravel once every five years to maintain the effectiveness of the filter.

These filter media are recommended for filters:

Volcano Filter

ALASKA Laminated Filter
