How to Safely Manage Your Backyard Inflatable Pool
Has COVID-19 turned you into a part-time backyard pool manager? Inflatable backyard pools are popular this summer as many families are choosing to steer clear of public aquatic venues to avoid contracting the coronavirus. I recently purchased a small inflatable pool for my family and we are enjoying the fun and relief from the heat just steps from our back door. Naturally, we are living together through the pandemic, so there is no need to maintain a social distance in the pool, as we would have to do in the presence of other swimmers in a public venue.
One thing that is very clear is that pools don’t take care of themselves. I found several online resources from which I developed the following tips for those of us who are “dipping our toes” into backyard pool management.
Tips for the Backyard Pool Manager
1.了解您的遊泳池持有多少加侖水。池中的水量將確定您將添加處理的池化學品。在線工具can help you calculate your pool’s volume. Did your pool come with directions for operating a filter or applying a sanitizer? Follow manufacturer’s directions. Small inflatable kiddie pools (approximately 3 – 5 feet in diameter) may be used without added treatment and emptied daily after use. The U.S. Centers for Disease Control and Prevention (CDC) offers有用的指導保持這些。
2. Choose a pool disinfectant.添加池製造商推薦的池消毒劑或在泳池供應商店尋求指導。許多遊泳池消毒劑是基於氯，含有穩定劑，以幫助防止陽光降解產物。您還可以購買產品以幫助調整池水pH值。您如何知道池中添加到泳池水中有多少？在線工具如此pool calculator可以幫助您根據您的池卷和推薦水平估計特定的化學金額。
暗示：常規氯漂白劑可用於消毒Kiddie池article in hunker.com。The article estimates 2 ounces of bleach is needed for a 150-gallon pool. Always test your water to ensure a chlorine level of 1 – 4 part per million (ppm) chlorine.
3.確定一種測試泳池水的方法。Backyard pool managers can easily use color test strips to monitor their pool water chemistry. Pool test strips can help you keep tabs on chlorine levels (“total” and “free” chlorine), and pH. Alternatively, you may prefer to use a liquid test kit.1As noted above, the pool water free chlorine level should be in the range of 1 – 4 ppm, and pH between 7.2 – 7.8. The “combined chlorine” level is not measured directly, but is calculated by subtracting the measured free chlorine level from the measured total chlorine level (more on combined chlorine in #4 below).
4.根據您的監控數據進行池化學調整。CDC calls chlorine and pH “Your Disinfection Team“為了防止休閑水疾病。這兩種化學因素代表了對水性病原體的前線防線，這可能會讓你的遊泳者生病。自由氯是可用於破壞水中病原體的氯。當水池水pH值為7.2和7.8時，氯最有效對抗病原體。該範圍還為遊泳者提供了舒適的環境。CDC推薦checking chlorine levels and pH at least twice per day, and more often when the pool is used heavily.
5. Shock your pool periodically.You can use either a chlorinated product or a non-chlorine shock oxidizer to break down combined chlorine in the water. Shocking the pool can also remove excess bather waste and visible algae. Shocking should be done when combined chlorine levels exceed 0.5 ppm. Shocking raises the pool disinfectant level 10 to 20 times the measured combined chlorine level. Keep your swimmers out of the water until the free chlorine reading drops back to 1 – 4 ppm. You may find it convenient to apply pool shock overnight to allow time for the free chlorine level to decline. Note: You can purchase chlorine decreaser (thiosulfate) at pool stores to reduce chlorine levels rapidly. Always follow manufacturer’s directions when shocking your pool.
- 視覺的: Can you see to the floor of the pool? Water clarity is extremely important to help prevent drowning. Cloudy water can conceal a drowning. If your pool water is cloudy,您可能需要一個藻類或水澄清器。
- 觸碰: When you touch the sides of the pool, is the surface clean and not slimy? A slimy surface indicates microbial growth, which could indicate the disinfectant level is too low. Time to test the water.
- 品嚐: There is no reason to taste pool water!
According to a2019年CDC報告泳池化學傷害導致2008年至2017年之間平均每年4,500多名急診部門訪問。2015年和2017年期間報告的大約一半的傷害發生在家，超過三分之一的兒童或青少年。這些是新的後院池管理人員的相關統計數據！
這是一個基本而重要的提示:閱讀和the time to understand pool chemical use and storage directions. For example, when working with pool chemicals, wear personal protective equipment, such as safety goggles, open only one chemical container at a time, and do so in a way that avoids your breathing chemical fumes or dust. Among pool chemical injuries requiring trips to emergency departments in the period 2015-2017, the top diagnosis reported by CDC was “poisoning due to breathing in chemical fumes, vapors, or gases—for example, when opening chlorine containers.”
