Why install a Redox controller for the pool ?

How to protect pool equipment from over-chlorination?

Swimming pools are privileged places of pleasure, a leisure activity at home that delights the whole family. But to enjoy swimming, time must be taken to maintain, monitor changes in water balance, and the presence of disinfectants... To limit measurements, controls, and the addition of disinfectant products... automatic treatment is an effective solution. When complemented by a Redox controller, it only remains to enjoy with serenity, a healthy and sparkling water.

What are the positive impacts of the Redox controller on the pool?

With automatic treatment (chlorine or salt...), chlorine production is linear and does not take into account meteorological factors or pool usage. The increase or decrease in chlorine production is defined by human actions taken on the device, and the effects are not immediate. The Redox control will determine the disinfectant power of the water regardless of the situation and adjust the disinfectant production automatically.

Does the Redox controller protect a covered pool?

When the pool is covered (roller shutter, cover, shelter, indoor pool...), chlorine production continues if the filtration is working. Therefore, there is often overproduction of disinfectant (unless the Redox level is frequently monitored and the chlorine production is manually adjusted each time the pool is opened and closed!). The water becomes aggressive and deteriorates the equipment.
For salt electrolysis, since the UV rays from the sun do not penetrate either the curtain or the cover, the transformation of hypochlorite into salt is not possible. The risk of over-chlorination is therefore increased.
The Redox control measures and automatically adjusts the disinfectant production according to the real needs of the water; thus avoiding over-chlorination, damage to the pool, and human intervention.

Does the Redox controller protect the liner?

When the liner is subjected to repeated over-chlorination, degradation results in premature aging, fading color, and stiffening due to deterioration of plasticizers.
Nowadays, pool liners are more sensitive to over-chlorination. Indeed, manufacturers follow the recommendations of institutions. They ask to limit materials or/and products harmful to the planet, and some protected the liner against treatment-related aggression. On the other hand, the choice of liner colors is increasingly darker. Since the coating is more sensitive to the "attacks" of excess chlorine, wear and discoloration are more visible.
The solution is to install a Redox controller. This equipment measures and adjusts chlorine production according to the real disinfection needs of the pool, no more over-chlorination, the liner is protected.

What are the advantages and disadvantages of a Redox controller?

Advantages of the Redox controller

The use of the Redox controller avoids over or under-dosing of disinfectant, provides bathing comfort by avoiding the inconveniences of poorly disinfected water, and thus prevents damage to pool equipment while preserving manufacturers' warranties.
For automatic chlorine treatment, the Redox control will reduce the consumption of disinfectant products by optimizing their effectiveness. For salt electrolysis treatment, it improves production while preserving the cell.
Regardless of the weather conditions, the number of bathers, the water temperature... the Redox control analyzes and guarantees healthy water under all circumstances. It autonomously manages these variations without human intervention.
Pool maintenance and monitoring are simplified. However, care must be taken to ensure the proper functioning of the devices, to calibrate the various probes, and not to forget to replace the pH or disinfectant containers when they are empty.

Disadvantages of a Redox controller

When the recorded level is too high or the probe malfunctions or is poorly calibrated, equipment can deteriorate, liner...
An inappropriate pH value, too much limestone, too much stabilizer, too high or too low alkalinity... all these factors disrupt and have an influence on Redox control. If the water is not balanced, the Redox analysis is distorted.

In France, unlike some countries, the installation of a Redox controller is not mandatory. However, when using automatic treatment for pools, it is an essential device. It improves and optimizes water disinfection, preserves pool equipment by avoiding over-chlorination, and simplifies maintenance for the greatest satisfaction of owners.
