What are the advantages of automatic water dosing?
Automatic dosing allows you to:
- Keep the water balanced continuously.
- Reduce the use of chemicals.
- Avoid manual dosing errors.
- Guarantee water quality at all times.
pH Redox Controller
What is a pH-Redox controller for swimming pools?
A pH-Redox controller is a device that continuously measures the pH and Redox potential (ORP) of pool water and automatically regulates the dosing of chemical products in order to keep water parameters within the ideal range.
Why is it necessary to control the pH of pool water?
Water pH directly affects chlorine effectiveness and swimmer comfort. If the pH is too high or too low, it can cause eye irritation, cloudy water, algae growth or limescale deposits.
What does Redox potential (ORP) measure?
Redox potential or ORP measures the disinfecting capacity of the water. When it has an appropriate value relative to the chlorine level, it is sufficient to eliminate bacteria, viruses and microorganisms present in the pool.
Is the pH-Redox controller compatible with salt chlorination?
Of course. pH-Redox controllers are the ideal complement to salt chlorination systems, as they allow the chlorine production of the salt chlorinator to be optimised and the water to be kept in perfect condition automatically.
Does a pH-Redox regulator require maintenance?
Yes, although its maintenance is quite simple. It consists of:
- Cleaning and checking the probes periodically.
- Performing periodic calibrations.
- Replacing the peristaltic tube when necessary.
This will ensure accurate measurement of water parameters and optimum system performance.
Can an automatic controller be integrated with other management systems?
Yes. Advanced models allow Modbus communication, wireless connection and remote monitoring, making integration into management systems for public pools, hotels or sports centres easier.
Are these types of systems useful for public pools?
They are not only useful but highly recommended. In public and communal-use pools, it is essential to maintain continuous control of water parameters. These automatic controllers help meet health regulations and guarantee safe disinfection.

Pool Types
Private Pools
What is salt chlorination in pools?
Salt chlorination is a disinfection system that automatically generates chlorine from salt dissolved in pool water through an electrolysis process. This system eliminates bacteria, viruses and algae without the need to manually add chemical chlorine, keeping the water clean, clear and more comfortable for swimming.
How much salt does a pool with salt chlorination need?
A pool with a salt chlorinator normally needs between 4 and 6 grams of salt per litre of water (check with the manufacturer). This concentration is very low compared to seawater, so it is barely noticeable when swimming and is much more comfortable for skin and eyes.
What advantages does salt chlorination have over traditional chlorine?
Salt chlorination in private pools offers multiple advantages:
- Softer, more pleasant water for the skin.
- Less irritation to eyes and mucous membranes.
- Automatic elimination of bacteria and microorganisms.
- Drastic reduction in handling chemical products.
- More comfortable and easier maintenance.
- Less chlorine smell in the water.
Is it difficult to install a salt chlorinator in a private pool?
Not at all. Installing a salt chlorinator is relatively straightforward and can be done in both new and existing pools. The system is installed in the pool’s filtration circuit and operates automatically once configured.

Public Pools
Can a public pool with a traditional chlorine system switch to salt chlorination?
Yes, of course. Practically any public pool can easily adapt a salt chlorination system to its installation.
Is salt chlorination suitable for any type of public pool?
Yes. A salt chlorinator is ideal for use in hotel and resort pools, schools, sports centres, residential communities, care homes, municipal facilities and more.
Is it legal to use salt chlorination in public pools?
Yes. Salt chlorination is permitted in public pools as long as the disinfection and control levels established by current health regulations are met.
Is salt chlorination suitable for large volume pools?
Yes. There are salt chlorinators designed specifically for public pools and large facilities, capable of generating large amounts of chlorine continuously to ensure correct water disinfection, even with a high bather load.

Camping Pools
Is an Innowater SMC salt chlorinator suitable for a campsite pool?
The most suitable salt chlorinator models for camping pools are usually the industrial models from the SMC-M and SMC-H ranges. Given the typical size of these pools and their intensive use, models from the domestic SMC salt chlorinator range are likely to fall short in performance.
Is a salt chlorinator sufficient to keep a campsite pool in perfect condition?
If the model is properly sized to the pool volume, yes. In any case, we must not forget the need to monitor pH and redox (ORP) levels in the water. We recommend installing automatic control systems such as the Innowater Monitor controller.
How much salt does a campsite pool need?
Initially, it will depend on the volume of water in the pool. It will be between 4 and 6 grams of salt per litre. Afterwards, you will only need to add more salt, in the same proportion, based on the amount of water that has evaporated from the pool — or in other words, based on how much new water has been added.
Can any campsite switch its pool from a traditional system to salt chlorination?
In our experience, to date we have not come across any campsite that could not make that change.

Rural House Pools
Is it necessary to install an automatic control and dosing system in a rural house pool with salt chlorination?
It is not mandatory, but it is highly recommended. It helps us to almost forget about the daily maintenance of the pool.
What is better for a rural house pool, a domestic or industrial salt chlorinator?
In most cases, given the usual size of this type of pool, a domestic salt chlorinator is sufficient. If the pool is very large and/or local regulations have other requirements, it may be necessary to use an industrial salt chlorinator model.
Is it easy to install a salt chlorinator in a rural house pool?
It is usually very straightforward. Generally, it takes no more than half a day to install (domestic salt chlorinator). It will depend mainly on the space available in the pump room or machine room.
Is it worth investing in a salt chlorinator for a rural house pool?
Absolutely. Just the fact of having better water quality and reducing maintenance would be enough. But also, the investment in acquiring the chlorinator is quickly recovered. Even more so in pools that are not very large.

Sports Centre Pools
Why is salt chlorination ideal for swimmers and athletes?
When a swimmer spends long periods in pool water, the more natural and gentle the water, the better. Salt chlorination is not aggressive on skin or hair, and helps avoid annoying eye irritation. That is why it is an optimal alternative for athletes and swimmers.
Does it take long to recover the investment of installing a salt chlorinator in a sports centre, spa or multi-sports facility pool?
This type of public pool is usually the one that recovers its investment most quickly. This is due to the large number of users and intensive use. Furthermore, salt chlorination serves as an attraction for swimmers who prioritise this type of pool over traditionally chlorinated ones.
How can I switch from traditional chlorine to salt chlorination in a sports centre pool?
The process is usually quite straightforward. First, determine the most suitable model for the installation (digital calculator). Then, visit the pool machine room to assess the available space and define the installation process, which usually takes no more than 1 or 2 days.
Why install a control and dosing system in a sports centre pool with salt chlorination?
The reasons are varied, but the main one is: automating water maintenance, minimising the need for constant supervision while keeping the water in optimal condition.

How long does it take to recover the initial cost of installing a salt chlorinator in a community pool?
Although this depends on different factors, in community pools with intensive use, the payback period is usually between 3 and 5 years.
Hotel Pools
Is salt chlorination cost-effective for a hotel establishment?
Absolutely. Thanks to salt chlorination, we not only make the swimming experience more comfortable and healthy for our guests, but at the same time we greatly reduce pool maintenance and the need for other water chemicals. We maintain the highest water quality for longer with an efficient and sustainable system, whose initial investment is quickly recovered.
Is salt chlorination suitable for any type of hotel pool?
Yes, with the sole exception of exposed stainless steel pools, whose manufacturers do not recommend the use of salt chlorinators in this type of pool.
When is the purchase of a salt chlorinator for a hotel recovered?
It depends on several factors: pool water volume, equipment purchased, usage time (summer, all year round…), type of use (occasional, intensive…). Usually, it ranges from 2 to 5 years, depending on the factors mentioned above.
Can I use any type of salt in a hotel pool?
As with other pools, we can use any type of salt, bearing in mind that the higher the purity, the cleaner the water, fewer residues and less maintenance.

Recommended levels of different water parameters in hotel pools
- pH: Between 7 and 7.4
- Redox (ORP): Between 650 and 750 mV (up to 800 mV with intensive use)
- Free Chlorine: Between 0.5 and 2 mg/L (ideally above 1 mg/L)
- Combined Chlorine: Less than or equal to 0.6 mg/L
Municipal Pools
How can I switch a municipal pool treated with traditional chlorine to salt chlorination?
The process is quite straightforward. After studying the pool characteristics and defining the most suitable salt chlorinator model, we simply need to make some minor adjustments to the existing filtration system and connect the salt chlorinator to the corresponding pipework.
Does a municipal pool with salt chlorination still need other chemicals?
Salt chlorination drastically reduces the need for other chemicals, but does not eliminate it entirely.
Is it necessary to continue monitoring pH and Redox levels in a municipal pool once a salt chlorinator is installed?
Yes. A salt chlorinator does not control and balance these values. We recommend the use of automatic control systems for this purpose.
