The Invisible Chlorine Thief: Why Your Pool Loses Chlorine Even on Cloudy Days
Even on overcast days, your pool’s chlorine levels can diminish due to ultraviolet (UV) radiation. While clouds may block visible light and heat, they are surprisingly ineffective at blocking harmful UV rays. According to the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), over 90% of UV rays can penetrate light cloud cover. This means your pool’s chlorine is still being consumed, even when the sun isn’t shining brightly.
Demystifying Pool Filters: Sand vs. Cartridge & The Best Media Choices
Most media filters come with a 10-year warranty, which is longer than the lifespan of a standard cartridge filter (about 2 years). Glass media itself can last for 8–10 years because it’s made from recycled glass bottles. These are harder than standard glass and less prone to erosion. On the other hand, sand media breaks down after about 5 years. This means that media filters can last 5 times as long as cartridge filters and glass media twice as long as sand!
