2. FAQs

How is the salt added and how often?
Salt is added directly to the pool water. Before putting the equipment into operation, the pump must be run until the salt is completely dissolved. The salt is not consumed in the process. It is only necessary to replace the salt loss caused by filter washing, topping up the water level, etc.
What kind of salt should be used? And how much?
Any type of common salt is perfectly acceptable. If very unrefined salt is used, temporary dirt or impurities may appear in your pool water, but this will not generally affect its chlorination. The recommended amount of salt is 5 to 6 kg per m3 of water in the case of unheated pools and 3 to 4 kg per m3 of water in the case of heated pools (28 - 30oC).
What is the recommended chlorine level in the water? And pH?
The recommended concentration of residual chlorine for private pools is around 1 ppm. In public swimming pools, this concentration is included in the regulations in each region and is usually around 1.5 ppm. For the chlorine to be effective, the pH must always be between 7.0 and 7.6.
Can a disinfected pool lose its chlorine after the water has been filtered?
If the filter is dirty, the amount of available chlorine in the water will decrease after it passes through the filter because the chlorine will react with organic matter in the filter.
Is salt chlorination compatible with the use of chemicals such as flocculants or algicides?
Salt chlorination is compatible with all types of chemical products, although, in principle, if you use your salt chlorination system properly, you will not need to add any additional products. On the other hand, Innowater chlorinators are provided with a shock dose function that can help water quality recover, if necessary.
Why doesn't the chlorine level rise in the pool if the salt level is correct and the pH is well regulated?
This usually happens in new pools or in pools that have recently had their water changed. Solar radiation and heat quickly break down the free chlorine in the water in a pool, so in pools with high sun exposure, the chlorine stays in the water for a short time, even though its production rate is high. Also, keep in mind that the chlorine produced by your chlorinator is pure and free of additives, which makes it especially reactive and, although this is one of its main advantages, it can lead to low concentration readings under these conditions. If you have difficulty maintaining residual chlorine levels in your pool, you can use a chlorine stabiliser.


The equipment indicates: "Low water level in the cell" or "NO WATER FLOW"
Check that the cell is full and that the water is reaching the water sensor (a small metal rod at the top of the electrode holder). If not, check the pump flow rate, filter, and pool water level.
The equipment indicates "Low salt", "Insufficient salt" or "Cell not detected"
Check the salt level in the water and that the electrodes are free from limescale. If there is limescale, clean the cell.
The water has a greenish appearance
This is due to the excessive presence of metal ions, which become coloured when disinfectant is added. The pH must be controlled by adjusting it to between 7.2 and 7.6. If it persists, you should super chlorinate and brush the walls and bottom of the pool.
Limescale has appeared in my pool
The appearance of limescale in a pool comes from hard water and high pH, as the calcium precipitates out of the water forming visible limescale. To fix this, you will need to flocculate: turn off the filter and allow the pool solids to settle. After 24 hours, clean the settled solids with a pool cleaner. Finally, adjust the pH to between 7.2 and 7.6 and continue with the usual treatment.
The alkalinity is too high or too low
An alkalinity higher than 225 mg/l will hinder pH stability and will cause corrosion. The water will take on a greenish hue that can cause eye irritation. To fix this, you will need to add hydrochloric acid or sodium bisulfide. On the other hand, an alkalinity less than 75 mg/l will also hinder pH stability. It is caused by the characteristics of the supply or filling water and by the addition of chemical products. To resolve this, add baking soda or sodium carbonate to the pool water.
