Now that the temperatures have started to fall, it’s time to think about how to best prepare your pool so it survives the winter season and is ready to use when the warmer weather comes around again.
Mr Pool Man has some great advice on how to winterise your pool!
How do I prepare my pool for Winter?
There are a number of steps you can take in order to ensure your pool is properly winterised! These include:
• Balance the water: The pool pH level needs to be between 7.2 and 7.6. Taking a sample of pool water to your local Mr Pool Man store will tell you exactly what the pH is or you are easily able to test it yourself by using test strips or a test kit. If the level is not correct, add the appropriate treatment to bring the pool to the correct level.
• Clean the pool! It’s important to brush the walls and floor of the pool and then to vacuum the whole pool thoroughly. Algae thrives in unclean water, so don’t forget to clean the skimmer baskets and the pump baskets of debris.
• Clean the filter: Ensure that the pool’s filter is sparkling clean, as any grease or oil deposits will harden over winter and make the filter harder to clean in the warmer months, not to mention reducing its overall efficiency.
• Use a shock treatment: It’s recommended to use a regular shock treatment throughout winter (once every month or so). Once you’ve added the shock treatment appropriate for your pool, run both the pump and filter for several hours to ensure it has been well distributed throughout the pool. Shock treatment is also known as adding 15L of liquid chlorine to your pool and 1-2L of acid. For more information on superchlorination or shocking your pool as well as dosage rates, read "Method #1" in our How To Get Rid Of Pool Algae blog.
• Protect against algae: Use an algaecide that’s appropriate for your pool.
• Check chlorine levels: To keep your pool clean and clear, it’s important to keep your pool’s free available chlorine levels at a constant level of 2-3 PPM (parts per million) at all times during winter. If you’re using a salt chlorinator and a pool blanket, remember to reduce the output of the chlorinator to 1-2 PPM, as pool blankets trap chemicals and chlorine, and can cause high chlorine levels to occur, resulting in damage to pool equipment if not monitored carefully.
• Maintain the pH and Total Alkalinity levels: Total Alkalinity (the measure of the ability of your pool or spa water to resist changes in the pH) is the overseer that keeps the pH of your water where it needs to be. If your buffering capabilities are too low (low alkalinity), your pH levels can swing drastically from highs to lows. Increase alkalinity by adding Buffer.
• Run the filter: The pool’s filter should operate for three to four hours each day. If you’re using a timer, adjust it to suit. Remember if you switch the filter on during off-peak periods, you can save money.
• Cover the pool: This will prevent water loss and also stop debris from entering the pool. Ensure you have a good quality pool blanket or cover.
• Keep up your maintenance schedule: Once you’ve completed your preparation for winter, it’s imperative that you stick to a maintenance schedule even though it’s cold and the pool is not being used. Once a week do a quick visual inspection of your pool and make sure all of your equipment is working properly, check the water level, empty the skimmer basket and check your chlorine and pH levels.
What is a good chemical to use in my pool during winter?
We recommend Zodiacs 1L Pool Long Life Alagecide.
The benefits of this product are:
Dosage rate: 200mL per 10,000L. Dosage rate indicated are a guide only. Please refer to the label for further instructions.
Brush the affected areas thoroughly.
Check the pH level to make sure it is between 7.2 and 7.6.
Add sufficient amount of purifier (sanitiser) to eliminate algae.
Add algaecide directly into the water and leave overnight with filter running.
It is recommended to add a clarifier to aid in the filtration process of dead algae. (Do not use a clarifier if you have a Cartridge Filter. Clarifiers and Flocculants will clog the papaer pleats in your sand filter to the point of no return.)
Following treatment, brush pool walls thoroughly and remove settled algae by vacuuming.
Do not add any product that would raise pH and Total Alkalinity for 72 hours after treatment.
