The process of winterising is based on adding a number of chemicals to your pool in order to keep the water in good condition over the winter so that it can be reused the following year. This considerably reduces the cost of getting your pool up and running the following year.
Winterising usually lasts for 9 months, although it can vary from one climate to the next. It is usually recommended that pool owners continue with conventional water maintenance until the temperature dips below 15 ºC.
There are many advantages to winterising compared to other water conservation systems or emptying your pool. It is therefore a very useful pool maintenance technique.
Some of the benefits of winterising include:
– The potential structural damage (cracks, holes, etc.) to which pools are prone is prevented and the entire pool facility remains in perfect condition so that it can even be used throughout the winter if desired.
– The winterising kit is very easy to use and maintenance requires no extra work.
– The substantial savings made, since the water can be reused for several years in a row (pools should be emptied approximately every five years) and the cost of getting the pool ready the following year is lower.
– The pool looks clean throughout the winter and is free from annoying insects and the algae that proliferate in stagnant, dirty water.
To winterise your pool correctly, we recommend that you follow the steps set out below:
1.- Make sure the water temperature is below 15 °C.
2.- Drain off a small amount of water to ensure that it does not overflow in the event of heavy rain. Never allow the water to drop below the level of the skimmer line.
3.- Clean the bottom of the pool thoroughly.
4.- Test and adjust the pool’s pH level. It should be between 7.2 and 7.6. If the pH level is too high or too low, we recommend that you use one of our pH adjusters such as CTX-10 pH- or CTX-20 pH+. We also recommend that you run the filter for eight hours to distribute the products evenly.
5.- Clean the pool filter. You can use a cleaner such as the CTX-55 to do this.
6.- Perform a chlorine shock treatment. This is basically to eliminate any microorganisms in the water. For this step we recommend that you use CTX-200/GR or CTX-250 ClorShock GR.
7.- Test the pH level again and adjust as needed until it is within the desired range.
8.- Add a winterising product such as CTX-550 and CTX-551C (for liners), which will keep the water free of algae and insects. Make sure you distribute it evenly around the pool and that the filter is running at full speed for even distribution.
9.- Close the inlet and suction nozzles to keep the water still.
10.- Remove the pool cleaner and protect the most sensitive equipment like pumps or salt chlorinator against the cold.
11.- Add floating devices to the water (empty plastic demijohns, tyres, etc.) to prevent the surface from freezing.
12.- Use your pool cover if you have one to keep leaves and other debris out of the pool.
Once you have performed all of these steps, you will have pretty much completed the process of winterising your pool. However, there are some very important steps you need to take during the winter to ensure that the water is being properly maintained.
We recommend the following maintenance:
– Add more winterising chemicals in January or February, depending on the weather conditions.
– Run the filter for 2–3 hours every 2–3 weeks to make sure it is not clogged and ready to operate at full capacity when the new swimming season begins.
– Check for leaves, sand and other debris in the pool if you do not have a pool cover, as such matter will obviously fall into the pool. Remove the largest pieces of debris from the pool and if the bottom is very dirty, use the filtering cycle to clean the bottom.
– Resume conventional water treatment in the spring, once the temperatures rise above 15 ºC.
