Try to clean your pool as often as possible with a quality pool cleaner. At the moment, few people follow these rules and because of this, their pools find themselves in different puddles or mud. My friend did this very often too, for a while he forgot about the pool, and then complained about why his pool is so dirty. After a while, I explained to him that he needed careful pool maintenance and that high quality pool cleaning products should be used. I even showed him a website with different pool cleaners, and now my friend cleans the pool at least twice a month (
