Shock Treatments: The "Rescue" of Your Pool

A summer storm, a heatwave, or a filter pump failure can turn a crystal-clear pool into a green swamp in a matter of hours. At Servinmosol, we don't believe in "draining and refilling" at the first sign of trouble. We apply professional shock treatments to kill bacteria, burn off organic matter, and restore water transparency, saving you thousands of liters.

When is a Shock Treatment Needed?

Daily maintenance is not always enough. Shock treatment (super-chlorination) is necessary when:

The Professional Secret: Prior Diagnosis

Have you added chlorine, but the water remains green? This is the most common problem we encounter.

The Stabilizer Lock: Chlorine tablets contain a stabilizer (Cyanuric Acid) to prevent the sun from degrading it. If this acid accumulates in excess (>75 ppm), it blocks the effect of chlorine. It doesn't matter if you add 20 kilos more; it won't work.

We analyze this parameter before acting. If there is a lock, we perform a controlled partial water renewal before applying the chemical treatment, guaranteeing success.

Our Step-by-Step Process

Pre-pH Adjustment: If the pH is not lowered to 7.0 - 7.2 before shocking, chlorine loses its strength and is wasted.
Intensive Brushing: Algae create a protective biofilm. We vigorously brush walls and the floor to expose them to the chemical.
Nocturnal Application and Continuous Filtration: The treatment is applied at sunset (so UV rays don't evaporate the product) and the filtration system must run for 24 hours uninterrupted.

Types of Treatment

Not all pools can handle the same chemicals. We adapt the product to your lining (Tiles or Vinyl Liner):

Granular Shock Chlorine (Dichlor): Fast and powerful action for tiled pools.
Active Oxygen (Peroxides): Ideal for liner or polyester pools, as it does not bleach the material. Allows for swimming almost immediately after application.
Flocculation: After killing the algae, we use flocculant to clump the dead particles on the bottom and use the manual vacuum in "waste" mode to leave the water spotless.
Is dirt embedded in the grout or do you have black algae stains that won't come off?

When stabilizer levels are unrecoverable or calcium scaling is extreme, a chemical shock won't solve the root problem. You need a complete reset.

⚠️ Safety Warning

Handling large quantities of concentrated chemicals is dangerous. The fumes released can cause severe respiratory burns.

Our technicians are equipped with the necessary PPE and calculate the exact dose per cubic meter to avoid damaging swimmers' skin or filtration equipment.
