The quality of your pool’s filtration media directly determines the clarity of your water. The Tecno Prodist Premium Silex Pool Filter Sand is the professional-grade silica sand with 0.4–0.8mm granulometry — the specific grain size engineered for optimal water flow and debris capture in standard pool sand filters. 10kg in a convenient bucket, ready for filter refills and multi-purpose use.
What Makes Tecno Prodist Silex Stand Out?
- 0.4–0.8mm granulometry — the industry-standard grain size for pool sand filters, engineered for optimal water flow and debris capture
- Premium silex (silica) composition — high-quality silica sand with superior durability and resistance to chemical breakdown from pool chemicals
- 10kg convenient bucket — practical packaging for standard filter refills, with enough sand for most residential pool filter top-ups
- Multi-purpose — also suitable for sandblasting and artificial grass installation
Why Granulometry Matters
Pool filter sand works by trapping debris particles as water passes through the sand bed. The grain size — granulometry — determines how effectively the sand captures debris while maintaining adequate water flow:
- Too fine: Restricts water flow, increases filter pressure, and requires more frequent backwashing
- Too coarse: Allows fine debris to pass through, resulting in cloudy water
- 0.4–0.8mm: The optimal balance — captures debris effectively while maintaining good flow rates and manageable filter pressure
Using the wrong granulometry is one of the most common causes of persistent pool water clarity problems. The Tecno Prodist Silex’s 0.4–0.8mm specification ensures your filter operates as designed.
Real-World Usage Situations
🏊 Pool Filter Maintenance
Pool filter sand needs replacing every 3–5 years as the grains gradually smooth and lose their debris-capturing effectiveness. The Tecno Prodist Silex is the replacement media that restores your filter to full performance — the 10kg bucket is the right quantity for topping up or partially replacing the sand in a standard residential pool filter.
🌞 The New Pool Setup
A new pool sand filter needs to be filled with the correct filtration media before first use. The Tecno Prodist Silex’s 0.4–0.8mm granulometry meets the specification required by most pool filter manufacturers, and the 10kg bucket format makes it easy to add the right quantity.
🛠️ The Seasonal Pool Opening
At the start of the pool season, checking and refreshing the filter sand is an important maintenance step. If the water clarity has been poor in previous seasons, replacing the filter sand with fresh Tecno Prodist Silex is often the most effective single intervention for improving water quality.
🏗️ Secondary Uses
The premium silica composition and consistent granulometry make Tecno Prodist Silex suitable for secondary applications including sandblasting (where consistent grain size is important for even results) and artificial grass installation (as infill material for drainage and stability).
