Shock Treatments: The "Rescue" of Your Pool

A summer storm, a heatwave, or a filtration failure can turn a crystal-clear pool into a green pond 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 clarity, saving you thousands of liters. We operate throughout the Region of Murcia and the Costa Blanca, bringing your pool back to health in record time.

When is a Shock Treatment Strictly Necessary?

Daily maintenance is not always enough. A shock treatment (superchlorination or chemical oxidation) is an emergency intervention required in the following situations:

• Green or Cloudy Water (Algae Proliferation): The walls are slippery, the bottom is not visible, and the water has lost its sparkle. Algae have taken over the pool, and the free chlorine level has dropped to zero.
• Massive Use in Summer: Especially critical in community pools and urbanizations. After a heatwave weekend with dozens of bathers, sweat, sunscreens, and urine saturate the water, demanding a weekly or biweekly preventive shock oxidation.
• Strong "Chlorine" Odor (Excess Chloramines): Paradoxically, if it smells very strong and irritates the eyes or skin, it's because the "good" chlorine has been depleted fighting dirt. The water must be "shocked" by multiplying the chlorine level by 10 to break down and volatilize those irritating molecules.
• After Heavy Rain or Calima (Saharan Dust): "Mud rain" is common in the Levante area. Rain washes in spores, Saharan dust, phosphates, and environmental pollutants that consume the sanitizer and unbalance the pH instantly.
• Biological Accidents: If a fecal incident, vomiting, or the appearance of a dead animal (rodents, massive insects) occurs in the pool. Following public health protocols, this requires an immediate high-concentration shock.

The Professional's Secret: Prior Diagnosis

Have you thrown in buckets of chlorine and the water is still green? It's the most common problem we encounter. Before pouring a single chemical into the water, we perform a comprehensive digital analysis, because typical color strips or phenol red drops are insufficient to detect the real problems:

• 1. Stabilizer Lock (Cyanuric Acid): Chlorine tablets contain a stabilizer so the sun doesn't degrade it. If this acid accumulates excessively (>75 ppm), it completely blocks the effect of the chlorine. It doesn't matter if you add 20 more kilos; it won't work. We analyze this parameter; if there is a lock, we perform a partial water renewal before acting.
• 2. Presence of Metals (Copper and Iron): If you fill with well water and do a chlorine shock without analyzing for metals, the water will instantly turn brown, black, or emerald green due to metal oxidation. We detect this in time to use sequestering treatments beforehand.
• 3. Phosphate Levels: Phosphates are algae "food." If levels exceed 500 ppb, any shock treatment will be temporary. We identify if we need to "starve" the algae before attacking it.

Our Step-by-Step Process (The Total Rescue)

A true shock treatment isn't just throwing in a chemical powder and leaving. It's a technical intervention spanning several days:

• Drastic pH Adjustment: If the pH is not lowered to 7.0 - 7.2 before the shock, the chlorine loses up to 80% of its disinfection strength and is wasted. We acidify it as a mandatory first step.
• Intensive Brushing: Algae create an invisible protective biofilm. We brush walls and the bottom vigorously to break that barrier and expose them to the chemical.
• Exact Nighttime Application: We calculate the exact ppm based on cubic meters. The treatment is applied at sunset (so UV rays don't evaporate the product in minutes) and with the filtration running.
• Flocculation and Draining (Waste): After killing the algae (the water will go from green to a cloudy milky white), we flocculate so everything falls to the bottom. Then, we manually vacuum directly to the drain (waste mode) so that dead biomass doesn't collapse the filter sand.
• Filter Backwashing and Transition: Finally, we backwash the filtration system and stabilize the water so it is safe for swimming.

Servinmosol's Arsenal: Types of Treatments

Not all pools can handle the same thing. As professionals, we don't just throw in "powdered chlorine." We select the exact chemical based on the problem, the lining (Tiles, Reinforced Membrane/Liner, or Polyester), and the water hardness in Murcia and Alicante:
