Pool Winter care

Take care of your pool during winter

You should winterise your pool when the water’s temperature falls below 15 ºC.

Thoroughly clean your pool by scrubbing the walls and running your pool cleaner over it. Clean the filter’s prefilter and the skimmer baskets making sure no leaves or other matter are left in them.

Test the water’s pH and make any necessary adjustments to obtain a pH of between 7.2 and 7.4. pH Minor or pH Plus can be used to regulate the pH.

Perform a chlorine shock treatment using trichloride blocks.

Leave the filter running for at least 4–8 hours so that all the products added become evenly distributed in the water.

On the following day, clean the filter using Extra Descaler. Place 0.5 kg of the product inside the pump’s prefilter or in the skimmer, set the filter valve to the filtration setting and briefly run the filter for just enough time so that the product reaches the inside of the filter in a dissolved state. Then stop the filter and leave the product to act for approximately 1 hour and then perform a thorough backwash.

If you have a liner, fibreglass or polyester pool, add the copper-free Power Winteriser. Do not use regular winterisers as they contain metals that could damage your pool’s surface finish.

If you have a glass mosaic or painted pool, there are two options: on the following day, add the Invernador winteriser or 1 unit of Inverlong. Then place the dispenser in the water cap-side down and leave it to float. It will last for approximately 4 to 6 weeks.

Let the filter run for 4–8 hours so that the product becomes evenly distributed in the water.

In the case of cold climates, drop the water level to below that of the skimmers, empty all pipes and the filter, and place a floating object on the water to act as a buffer against the pressure of ice, unless you use Inverlong.

In warmer climates, regularly run the filters whenever posible.

To prevent your pool from filling up with dirt, it is recommended that you cover your pool with tarpaulin or a pool cover.

It is important to repeat the treatment with your winteriser or copper-free winteriser halfway through the winter season

For pools that have salt chlorinators, it is recommended that the water be treated by following the steps described below:

If the water temperature is above 15 ºC, the chlorinator should be left to run for enough time to keep residual chlorine at acceptable levels (0.5–1.0 ppm) by manually or automatically adjusting the pH to between 7.2 and 7.4. The lower the temperature, the less time the filter needs to be run.

If the water temperature falls to below 15 ºC, you should follow these steps:

Disconnect the chlorinator from the mains and take out the chlorine generator cell. Clean it using an electrolytic cell cleaner to remove any limescale that may have built up on the plaques.

Store the chlorine generator cell in a dry place protected from adverse weather conditions.

If you have a pH or pH/Rx control and regulation system, you should remove the pH or Redox electrodes very carefully, place them in a preservative solution, either in the original casing or a glass, and store them in a dry place protected from adverse weather conditions. The ph and Redox electrodes undergo natural aging, even if regularly treated as described above. They have an average lifetime of between one and a half and two years. During storage, check that the tips of the pH or Redox electrodes are coated in the KCL 3M preservative solution supplied by the manufacturer.

In the case of evaporation or accidental spillage, pour a little of the KCL 3M solution onto the cap or protective casing. It is crucial that the cap or protective casing always be kept moist with this solution. The electrodes should be stored in a dry place between 10 and 30 ºC.

Follow the conventional winterisation treatment.
