Frequently Asked Questions
Add chlorine regularly (daily or every few days) to keep a steady level, and shock about once a week if needed. What chlorine, pH and alkalinity levels should I aim for? Target chlorine 1–3 ppm, pH 7.2–7.6, and alkalinity 80–120 ppm.
In general, shocking at night is best to allow your chlorine to work most effectively without having to fight against reactions caused by the sun's UV rays.
The correct place to put chlorine depends entirely on the type of chlorine you are using. Always ensure your pool pump is running while adding chemicals.

Choosing between a garden hose and a water truck comes down to your budget, how fast you want the pool filled, and your home’s water source. In most cases, a garden hose is significantly cheaper, while a water truck is much faster.
All pools lose some water daily due to evaporation. Under normal conditions, expect about 1/4 inch per day, with weekly losses typically ranging up to 2 inches at most. However, factors like high temperatures, low humidity, wind, and pool activity can increase evaporation, leading to greater water loss.
Pool shock is a chemical treatment that helps break down contaminants – such as leaves, dirt and debris, even oils from your skin -- that can gradually build up in your pool water. Shocking your pool as part of your weekly pool maintenance routine will help keep your water clear and balanced.
Most swimming pools universally prohibit glass containers to prevent dangerous shattering, running and horseplay to avoid slips and injuries, and swimming while ill with diarrhea to stop the spread of recreational water illnesses.
Pool pumps should run 8 to 12 hours daily, with some of that time during the hottest part of the day. In high heat or high-use periods, run the pump for 12–16 hours, or up to 24 hours if treating cloudy water or algae.
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.
Without chlorine or a sanitizer, pool water will generally stay safe and clear for only 24 to 48 hours. After this short window, bacteria multiply rapidly, and algae spores begin to bloom, which can quickly turn the water cloudy or green.
The fastest way to fix it is to test your water, balance pH and chlorine levels, remove debris, and run your filtration system continuously for 24 to 48 hours. If your pool still looks cloudy after that, the problem is often deeper, such as hidden chemical imbalance or algae beginning to spread.
free residual chlorine concentration in your pool should be maintained at 1.0 to 3.0 mg/L. The ideal level is 2 mg/L. When a pool is not in use, a method such as a floating immersion dispenser should be used to maintain a disinfection residual in the pool water at all times.
A normal pool loses about 14one-fourth14 inch of water per day (about 2 inches per week) due to evaporation. However, under hot, dry, or windy conditions—or when using water features—daily loss can reach 12one-half12 inch. Losing more than 12one-half12 inch to an inch daily strongly indicates a leak.
In most climates, you'll need to add water once or twice a week during the swimming season. Adding water more often than that may indicate a leak, especially if your pool is losing more than ½ inch per day.
A typical pool pump lasts 8 to 12 years with regular maintenance, though high-quality variable-speed models can occasionally reach 15 years. The motor usually needs replacement or significant repair every 7 to 9 years.
On average, most single speed pool pumps should operate for at least 8 hours every day. The rule of thumb is to run your single speed pump one hour for every 10ºF of outside air temperature. On the other hand, variable speed pumps typically need to run a bit longer than 8 hours.
Swimming in a pool with low chlorine exposes you to harmful bacteria, viruses, and parasites that cause waterborne illnesses. It also increases your risk of skin infections, eye irritation, and gastrointestinal issues.
Two gallons of liquid chlorine will shock a 10,000-gallon pool. However, the exact amount needed depends entirely on your pool's volume and current condition. A standard rule of thumb for liquid chlorine (at 10% to 12.5% strength) is:
The fastest ways to fill a pool are hiring a pool water delivery service or connecting multiple garden hoses to different, independent water sources (e.g., your home tap, a borrowable neighbor's hose, or an exterior wash-sink tap).
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's startup phase is when the interior surface cures, the water chemistry stabilizes, and the entire system settles into balance. These first few weeks determine how your finish will look and how easy it will be to maintain your pool in the long run.
