5 Quick Drowning Prevention Tips for Kids

Image
  Keeping children safe around water doesn’t have to be complicated. These five actionable tips help reduce drowning risks and give parents, caregivers, and kids clear steps to follow every time they’re near a pool, lake, or beach. 1. Always Maintain Active Supervision Children should never be left unattended in or near water, even for a moment. Designate a “water watcher” whose sole job is to keep eyes on the kids—no phones, conversations, or distractions allowed. Rotate this role every 15–30 minutes to ensure vigilance stays sharp. 2. Teach Age-Appropriate Swim Skills Enroll children in swimming lessons as early as possible—many community centers offer water familiarization classes for toddlers. Focus on basic skills like floating, treading water, and safe entry/exit techniques. Reinforce these skills regularly so they become second nature. 3. Require Proper Flotation Gear Life jackets or approved personal flotation devices (PFDs) should always fit snugly and be Coast Guard–appro...

Don't Neglect the Filters

Image
  Essential Guide to Pool Filter Cleaning: What to Look For Regular pool filter maintenance is vital for clean, clear water and efficient circulation. Neglecting filter cleaning can lead to higher chemical use, equipment strain, and poor swimmer experience. This guide breaks down methods for sand, cartridge, and D.E. filters, highlights key warning signs, and offers best practices to keep your system running smoothly. Why Regular Filter Cleaning Matters Regular cleaning prevents debris buildup that restricts water flow and drives up pump pressure. A clean filter maximizes filtration efficiency, reducing chemical consumption and energy costs. Proactive maintenance extends the lifespan of filter media and pump components. Types of Pool Filters and Their Cleaning Methods Sand Filters Backwash to flush out trapped dirt. Inspect laterals for breaks and sand levels yearly. Cartridge Filters Remove cartridges and rinse with a hose. Soak in filter cleaner quarterly to dissolve oils and sca...

Why Blonde Hair Turns Green in the Pool

Image
  The Science Behind the Tint Blonde swimmers often return from the pool with an unexpected souvenir: a greenish tint to their hair. While it’s easy to blame chlorine, the real culprit is copper—its presence in pool water, combined with oxidation, leads to that telltale hue, especially in light or porous hair. Copper, Not Chlorine, Is to Blame Copper ions—from pennies turning green to the Statue of Liberty’s patina—oxidize when exposed to pool water and chlorine. As copper oxidizes, it leaches into the water and binds to the proteins in hair shafts, depositing green-tinted particles. How Copper Enters Pool Water Municipal or Well Water Sources Many well-water supplies naturally contain dissolved copper. Even some city water systems can have elevated copper levels, seeding pools with the metal. Copper-Based Algaecides Copper is a powerful algaecide, so many pool owners use copper-bearing treatments to prevent algae blooms. Overuse or improper dosing raises copper concentration...

Glass - The Hidden Hazard

Image
  Glass in Swimming Pools and How to Prevent Injuries Swimming pools are meant to be oases of fun and relaxation, but a single shard of glass can turn them into dangerous traps. Whether it’s a stray bottle, shattered tabletop, or broken light fixture, glass poses unique risks that often go unnoticed—until someone gets hurt. Understanding these dangers and implementing strict protocols is essential for any pool operator, public facility, or homeowner. Common Sources of Glass Intrusion Beverage Containers : Beer, soda, and wine bottles are frequent culprits at pool parties. Glass Table Tops &ware : Outdoor tables and dishware can topple in wind gusts or collisions. Pool Lighting : Overhead fixtures and internal pool lights use glass components that may shatter under stress. No matter the source, once glass enters the water it becomes nearly invisible, making removal and injury prevention extremely challenging. Why Glass Is Especially Dangerous Invisible Underwater Glass shards...
