Switching Sand to Glass: A Revolution for Your Filter

The filter is the lungs of your pool. If the filter media is exhausted, you can add all the chemicals in the world, but the water will never be perfect. At Servinmosol, we recommend replacing traditional silica sand (which must be changed every 4-5 years) with Eco-Friendly Filter Glass, a definitive load that radically improves water quality.

Why Does Sand Stop Working?

Over time, silica sand suffers from two serious problems:

• Biofilm: Bacteria colonize sand grains, creating a sticky layer (biofilm) that clumps the sand together and creates "preferred channels." Water passes through these channels without actually being filtered.
• Wear by Erosion: Grains lose their sharp edges and become round, losing their ability to trap fine dirt.

Advantages of Filter Glass (Eco-Glass)

Filter glass is made from recycled glass treated so it doesn't cut. Its advantages are both technical and economic:

1. Microscopic Filtration

While sand traps particles up to 20 microns, high-quality glass can trap down to 1 micron. This means visibly clearer and brighter water, free of turbidity.

2. Water & Energy Savings

Since it doesn't clump, backwashes are much faster and more effective. You will save thousands of liters of water per year in backwashing and reduce the pump's electricity bill.

3. "Infinite" Durability

Unlike sand, which degrades, filter glass loses barely 1% of its volume per year. It practically lasts the entire lifetime of the filter, making it a one-time investment.

Our Replacement Process

We don't just "pour bags." We perform comprehensive maintenance on the equipment:

1. Emptying & Cleaning: We extract the old sand (a heavy and dirty task) and clean the inside of the tank with descalers.
2. Checking Laterals (Crepinas): This step is vital. We check the bottom diffusers (laterals). If broken, the media would leak into the pool. We replace them if necessary.
3. Stratified Loading: We fill the filter with glass of different grain sizes (coarse at the bottom, fine at the top) to maximize hydraulic efficiency.
