When it comes to pool maintenance and closing, there are a few dangerous myths that we’ve heard from well-intentioned pool owners over the years. We’re going to share what those myths are and why these not-so-good “how to clean a pool for the winter” ideas should be completely avoided:
Myth #1: Drain Your Pool
Misguided pool owners believe that part of winter pool maintenance includes completely draining the pool. This could potentially be the most dangerous action that you can take with your pool. Apart from minor problems that can arise (i.e. a shrinking pool liner) you can destroy the foundation of your pool.
Cleaning should very seldom be a reason to drain your pool, and even then should only be performed by a professional pool maintenance company. For the most part, the only time you’ll need to drain a pool is if a repair is needed, or if the Total Dissolved Solids (TDS) need to be stabilized.
Myth #2: Cooler Weather Will Kill Algae
If you’re trusting on cooler temperatures to keep pool algae at bay, then you’re guaranteeing yourself a green pool come spring, especially here in Mississippi where the average winter temperature is in the mid-fifties. Though you may be “closing” your pool for the winter, you’ll still need to regularly test your pool chemistry and make sure that it’s balanced, paying particular attention to your pool’s pH levels which should sit anywhere between 7.0 to 7.4ppm.
Myth #3: Don’t Refill the Pool
In some instances you may need to drop the pool’s water level ever so slightly to accommodate different types of pool covers. That said, the water level of your pool should never drop 18” lower from the top of your pool. This can not only result in increased pool maintenance and repairs, but it can also destroy your pool cover (i.e. covers can stretch and rip, anchors can pull out of your pool decking).
