Summering your pool
Once your water temperature gets above 12°C, it is time to put your pool back in action to avoid the appearance of algae and other micro-organisms at the start of the season.
1.Start by removing everything that has helped to winterize the pool
Take off the cover (think about cleaning it, letting it dry, folding it and storing it for ease of mind for the end of the season). Be careful, don’t drag it along the ground, it could be damaged.
Also remove any floats (making sure you are careful of any ice/frost)
2. Clean your pool
Clean all around your pool :
Use a net on the bottom and the surface, brush the walls, clean the water line, use a manual or robotic pool cleaner.
Also think about the edges and the tiles around the pool. Give them a quick sweep.
The more the surrounding area of your pool is clean the less impurities your pool will contain. It is best to clean the surrounding area after having taken off the cover (this often contains dirt and other impurities).
3. Turn all your equipment on :
Think about putting the baskets back in the skimmers and screw the adjustable jets back in their positions.
Top up your water level (the new water should be about 1/3 of your total volume) : it is advised that you change the water in your pool each year, above all to remove residue of products, stabilizers (present in chlorine tablets), limescale, metal, microorganisms and waste of all forms.
Instead you can completely change the water every 4 years (it is more effective to change a bit each season).
4. Now go to the machine room :
- Clean the filter
Carry out a good clean to start the season in the best condition.
For sand filters, perform a backwash then a rinse (both directions).
In the case where your you use a cartridge filter, put in new cartridges.
- Careful inspection is necessary :
Getting your pool back up and running quite early will allow you to carefully keep an eye on your pool and be able to react if there is a problem and call a professional.
Check for appearance of possible cracks in the pool or area around it, also check your filtration system.
It will be easier to make any repairs before the arrival of summer.
Once the pool is clean, put your accessories back into the water (stairs, diving boards).
5. Replace a bit of your water.
Each year you should empty a third of your pool using the plug at the bottom to remove the products that have accumulated during the previous season.
Recharge your ICO, recalibrate its sensors (pH + Redox/ORP) and put it back in the water
6. The analysis of the equilibrium of your water
Once cleaning has been carried out, do a complete analysis of your water. Check the following elements and if you need to adjust them :
It is measured on a scale of 0 to 14, for best comfort it should be between 7,0 and 7,2. Chlorine is 75% active in between these readings.
The level of stabilizer
For a chlorine treatment it should be at 30mg/l maximum
Ideally around A =20°F
A <20°F the water is soft and corrosive.
A >20°F the water is hard and can lead to limescale.
Ideally between 100 and 250 ppm
It is part of the buffer effect in water, that is to say it stops big variations in your pH.
To best analyse the quality of your water, ICO can help you and will send you notifications and actions straight to your smartphone.
7. Carry out a shock treatment
If it has not been done before hibernation, it is recommended that you carry out a shock treatment on your pool, with chlorine, bromine or oxygen active liquid according to the normal treatment of your pool.
Well done, everything is ready, you can now leave your filter to work for 24 to 48 hours continuously to stabilize the water in your pool.
