You should completely change your pool water every 3 to 5 years (or up to 7 years in milder climates). However, rather than doing it based on a strict timeline, you should drain and refill based on chemical testing, specifically when Cyanuric Acid (CYA) or Total Dissolved Solids (TDS) reach maximum limits.
Most pool experts recommend changing your pool water every two to three years. This timeframe is a general rule of thumb, but several factors influence how often you need to drain and refill your pool. Regularly monitoring your pool's water quality can help you decide if it needs to be changed sooner.
The 25:10 rule states that if a child is unable to swim 25 meters continuously (no stopping) and unassisted, then a parent needs to remain in the water with them within 10 feet of the child.
People who maintain poor water chemistry need to drain their pool around every 3-5 years. People with great water chemistry need to drain it every 5-7 years. Just to average it out, pool water should be completely drained every 5 years. Or, when certain levels get too high.
Yes, norovirus can survive in swimming pools. While proper chlorination kills the virus within minutes, norovirus is highly resistant to standard disinfectants and can survive for days in inadequately treated water or on pool surfaces. Swallowing just a small amount of contaminated water can cause illness.
Yes, you can get viruses from swimming pools. The most common way viruses (such as norovirus, adenovirus, and hepatitis A) spread in pool water is through accidental fecal contamination or contact with bodily fluids from other swimmers.
Norovirus diarrhea is typically very watery or loose, and often comes on suddenly in large, frequent volumes. It generally has a strong, foul odor and is light brown, yellow, or greenish in color. It rarely contains blood or mucus.
Baking soda (sodium bicarbonate) acts as a natural buffer that raises both your pool's total alkalinity and its pH. It prevents severe pH fluctuations (known as "pH bounce"), clears cloudy water, prevents equipment corrosion, and helps your chlorine sanitize more effectively.
What is the normal evaporation in a swimming pool? Generally speaking, pools lose approximately 1/4” of water per day on average, though this can vary due to factors like wind, temperature, humidity and of course, the pool's total surface area.
In swimming, the 80/20 rule generally refers to one of two core principles: Training Intensity Distribution (spending 80% of your time on easy swimming and 20% on hard efforts) or the Pareto Principle (fixing 20% of your technique issues to correct 80% of energy waste).
Yes, you can absolutely lose belly fat by swimming. It is a highly effective full-body, low-impact cardio workout. An hour of swimming burns between 400 to 700+ calories depending on your weight and intensity. However, the trick is understanding how targeted fat loss works.
The United States is historically and statistically the best swimming country in the world. The U.S. leads the All-Time Swimming Medal Table with an unmatched 258 Olympic gold medals, largely anchored by legends like Michael Phelps and Katie Ledecky.
It is generally not recommended to swim in a pool while you have a urinary tract infection (UTI).
For concrete or gunite pools, the shell is often the single most expensive component. Furthermore, it requires extensive engineering and highly specialized labor.
The term ghost pool generally refers to one of three things, depending on whether you are talking about billiards, public history, or swimming pool construction.
Your pool is likely losing water during the winter due to winter evaporation or accidental siphoning (if you use a cover pump). Other common culprits include water displacement from a heavy snow load, or an actual winter leak in the liner, skimmer, or plumbing lines.
The rate of water evaporation varies depending upon location, temperature, humidity and wind, but it isn't uncommon for an uncovered swimming pool to lose 5mm of water per day on average.
A sore throat from a chlorinated pool is usually caused by chloramines, which form when chlorine binds to sweat, oils, or urine in the water. These irritants become airborne gas, inflaming your throat. Mild irritation usually clears in a few hours.
Adding vinegar (acetic acid) to a pool temporarily lowers the water's pH and helps dissolve calcium buildup. However, it is a weak acid. Because you need massive quantities to adjust pool chemistry, it introduces organic sugars that can feed bacteria and algae.
To get pool water crystal clear, balance the pH (7.47.47.4–7.67.67.6) and alkalinity (808080–120120120 ppm), shock the pool to kill contaminants, and run the filter 24/7 until clear. Regular maintenance, including brushing, vacuuming, and using a clarifier, removes fine particles that cause haze, such as dust and oils.
Ideally, your pH is between 7.2 and 7.8 and the alkalinity is between 110 and 150 ppm (parts per million). If your alkalinity level is lower, and especially if less than 80 ppm, then you need to raise the pool water alkalinity. Purchase baking soda in bulk (available in pouches up to 15 lbs.).
Unusually long poops (up to 2 feet) usually happen because of constipation, a high-fiber diet, or the physical size of your colon. If you skip a "poop session" or don't go as frequently, your bowel holds more waste, leading to a much longer single stool when you do finally go.
Black Poop
Black stool can mean there's dried blood present in your poop, and internal bleeding occurred somewhere in the upper gastrointestinal tract — far enough away from the rectum that the blood had time to dry. Call your doctor if you notice you have black stool. This can be a sign of a serious digestive problem.
Many gastrointestinal conditions may cause foul-smelling diarrhea, including: other infections, like norovirus.
