Key Features & Benefits
Glass media has a finer, more angular structure than standard sand, allowing it to capture smaller particles (down to about 5–10 microns) and improve water clarity by roughly 20–30% compared with traditional pool sand.
It is also non‑porous, which helps reduce channeling and biofilm buildup, leading to cleaner, more stable water filtration system performance.
Replace the existing sand in your sand filter with this glass media, usually using about the same or slightly less weight (many manufacturers recommend around 80% of the original sand‑weight for the same volume).
Usage Tips
- Keep any required under‑layer of pea gravel if your filter instructions specify it, to prevent media loss into the distribution laterals.
- Resume normal backwashing as per your filter’s manual; many glass‑media brands note that backwash cycles can be shorter because the lighter media fluidizes more easily, saving water and energy.
- Using Glass Media BT Sand Filter 20 kg (Spanish‑made) helps upgrade your pool filter from basic sand to a more efficient, environmentally friendly option without changing the filter body. When paired with your pool equipment, pool supplies, and regular maintenance, it supports cleaner, clearer water and can reduce the frequency of backwashing and chemical demand over time.
