什么是冲击游泳池或水疗中心？

对游泳池或水疗中心进行冲击处理、消毒或氯化处理是向游泳池或水疗中心的水中添加氯，以提高和维持游离氯 (FC) 的推荐水平：非盐水游泳池为 2-3 ppm，盐水游泳池为 3-4 ppm，热水浴缸为 3-6 ppm。

冲击游泳池也可能意味着 SLAM （冲击水平和维持），即在泳池中添加氯，并根据氰尿酸水平将非盐水泳池的 FC 水平保持在 12ppm 至 24ppm 之间，盐水泳池的 FC 水平保持在 28ppm 至 31ppm 之间，以杀死 藻类 或者 氨 这是由于泳池和水疗中心的卫生状况不佳造成的。

Adding chlorine to your pool or spa daily or weekly, depending on the type of chlorine shock you use, is vital. This is because chlorine sanitizes water by eliminating harmful germs and bacteria, which cause murky water, algae, and ammonia in swimming pools.

氯还可以消除氯胺或结合氯 (CC)，这种物质是由于泳池使用或太阳紫外线照射导致水中的 FC 水平 (FCL) 降低而形成的。

结合氯会使泳池水变得浑浊，产生更多的氯气味，并且无法对泳池或温泉水进行消毒以防止有害细菌和病菌。

If you don’t have a 盐水氯发生器，您需要每天或每周至少一次手动向水中添加氯，具体取决于您使用哪种氯冲击来维持泳池或水疗中心建议的 FCL。

You don’t need to manually add conventional chlorine to a saltwater pool because the Saltwater Chlorine Generator (SWCG) does it for you. However, if you have cloudy water in your saltwater pool, 学习 h如何维护咸水池 然后选择关闭氯气发生器，手动使用氯气对泳池进行冲击处理。

另外，如果您经营着一家水疗中心，并且想知道如何消毒，我们建议您使用氯。这是因为即使使用溴等非氯氧化剂，您仍然需要使用氯来确保水疗中心有效运作。

Before we go into how to shock a pool or spa to clear cloudy water, let’s discuss a few details you need to know before shocking the pool, like when to shock, time to shock, and the best chlorine shock to use.

多久之后我要对游泳池和水疗中心进行冲击处理？

一个良好且推荐的做法是每天晚上测试您的FC水平，如果低于建议水平，则将其调回至建议水平。请记住，水疗中心的热水会使热水浴缸中的化学物质发挥作用，并且比没有热水器的游泳池更快耗尽。 

The duration to shock your pool or spa will largely depend on the type of chlorine you use to shock your pool, including granular, liquid, trichlor, or dichlor.

如果您使用液氯（次氯酸钠），当泳池或水疗中心繁忙时，您需要每天至少对泳池或水疗中心进行一次冲击处理。

You will shock your pool weekly using granular chlorine(calcium hypochlorite), trichlor, and dichlor.

我如何知道泳池中的游离氯含量低？

保持泳池和水疗池水的化学平衡是轻松维护泳池的第一步。因此，您需要一个非常准确可靠的泳池化学测试套件，例如 LaMotte ColorQ Pro 7 测试水中的所有化学物质，包括 FC、TC、pH、总碱度 (TA)、氰尿酸、钙硬度和溴（适用于溴维护的游泳池和水疗中心）。 

The other way to know your FCL is low is when your water is cloudy and has a strong chlorine smell. However, it would be best not to wait until your water is cloudy to shock your pool because you might have bacteria causing algae and ammonia.

对游泳池进行冲击消毒的最佳时间是什么时候？

对游泳池进行消毒的最佳时间是傍晚，那时太阳已经落山。这是因为太阳的紫外线 (UV) 会更快地消耗掉游泳池中的氯，如果在白天进行消毒，FC 会快速降低，导致游泳池容易受到有害细菌的侵害。  

氯冲击的类型以及最适合泳池使用的氯冲击剂

这一点非常重要。市面上有好几种氯冲击剂，你需要了解你正在使用的氯冲击剂的类型及其副作用。 

1. 液氯：第一个也是最推荐的氯冲击是液氯，也称为 次氯酸钠.

Liquid chlorine is similar to regular household bleach but much stronger, with 10% to 12.5% available chlorine. Regular bleach comes with 5% to 8% available chlorine, making it weak to sanitize a swimming pool or spa properly.

建议使用次氯酸钠对泳池水进行日常消毒。因为它不会在水中沉积其他化学物质，包括钙和氰尿酸。

Sodium hypo has a low acid ratio compared to dichlor and trichlor and, therefore, doesn’t lower pH and alkalinity levels like granular, dichlor, and trichlor.

液氯也更有效，因为它能与水更快地混合，杀死细菌和病菌，从而产生藻类和氨。

哪里可以买到液氯？

There are several liquid chlorine products on the market today. However, most are below the standards to sanitize pool and spa water. 

If you live in the USA and are asking where to get the best liquid chlorine for your pool or spa, visit the HASA Sani-Clor website.

Alternatively, you can physically find HASA Sani-clor dealer near you and buy HASA Sani-Clor liquid chlorine, which is the best liquid chlorine I have ever used: It’s calcium-free, pH neutral, non stabilized, and stronger with 12.5% chlorine (Sodium Hypochlorite).

如果你买不到 HASA Sani-Clor 液氯，你可以使用次氯酸钠制成的最佳替代品牌，例如 泳池冲击液氯器, coming with 12.5% available chlorine and 泳池必备氯化液 这也是10%有效氯。

2. 颗粒氯：也称为 次氯酸钙， granular chlorine is the most common pool shock because most pool owners don’t prefer daily sanitization.

Calcium Hypochlorite is always 40% to 78% available chlorine and comes with high Calcium levels. Using it requires closely monitoring your water’s Calcium Hardness (CH) levels. Otherwise, you will fight the unending 钙质结垢 问题。

3. 二氯 （稳定氯）：二氯含有约 56% 有效氯，在转换为不稳定液氯之前，最适合用于启动水疗中心或热水浴缸。

二氯始终是新鲜补充装的最佳推荐。因为它含有相当比例的有效氯和氰尿酸，与浓度更高的三氯相比，它不易损坏泳池或水疗中心。

当氰尿酸水平达到 30 ppm 至 40 ppm 时，您需要从使用二氯转为使用液氯。

 4. 三氯 (stabilized chlorine): Trichlor is the strongest chlorine pool shock. It comes with 80% to 90% available chlorine and is always in tablet form.

Trichlor is a stabilized chlorine with high levels of Cyanuric acid (chlorine stabilizer). Trichlor might be ideal for fresh pool and spa water with high initial FC and cyanuric acid levels. Also, when your pool or spa is attacked by algae or ammonia, it needs very high free chlorine levels to clear.

否则，我总是尽量避免使用三氯，因为它含有高浓度的有效氯和稳定剂，对泳池及其使用者的健康有害且危险。氯氟烃浓度过高可能会损坏泳池或水疗中心的表面。

You can use tablet chlorine as a start-up shock but shift to unstabilized liquid chlorine when the Cyanuric acid level reaches 30 ppm – 40 ppm for non-saltwater pools and 70 ppm to 90 ppm for saltwater pools. 

长期使用稳定氯维护的游泳池和水疗中心可能会受到高氰尿酸 (Cya) 水平的影响。

氰尿酸水平过高的缺点是，为了降低其水平，您必须将游泳池或水疗中心的水部分排干，然后重新注入淡水。 

I guess this information will guide you in choosing the best chlorine shock to use in your pool or spa, but we highly recommend you use liquid chlorine to sanitize your pool and hot tub for a trouble-free swimming pool.

What is the Ideal Cyanuric Acid Level when Shocking My Pool or Spa?

氰尿酸（氰基）是一种氯稳定剂，其在水中的含量将决定 FC冲击水平，无论是清除浑浊的水还是杀死藻类或氨。

水中的氯稳定剂（Cya）越多，达到相同效果所需的氯就越多，因为在高氰尿酸水平下氯会变弱。

The ideal chlorine and Cyanuric acid level depends on why you add chlorine. For pool sanitization, FC reading should always be 2-3 ppm with a cyanuric acid level of 30 ppm to 40 ppm for non-salt water pools and spas, 70 ppm to 80 ppm for a saltwater pool and spas, and 20 ppm to 30 ppm for indoor pools and spas. 

Cyanuric acid is essential for your pool because it stabilizes chlorine, making it last longer.

然而，在水中添加氰尿酸时要非常小心；排出并重新注入部分泳池和温泉水是降低其含量的唯一方法。

使用氯消毒泳池和水疗中心的 3 个简单步骤

1. 测量液体、颗粒和稳定氯的正确剂量 

氯剂量：一般测量：

1磅/1磅=盎司×0.062500 

• 次氯酸钠（液氯）：10 液体盎司（oz.）的液氯与 12.5% 氯（即 HASA Sani-Clor 液氯）可使 10,000 加仑游泳池或水疗中心的 FC 水平提高 1 ppm。13 液体盎司（oz.）的液氯与 10% 氯（即 KemTek 氯化液）可使 10,000 加仑游泳池或水疗中心的 FC 水平提高 1 ppm。
• 次氯酸钙（颗粒）: 2 oz. of calcium hypo with 67% chlorine raises FC level by 1 ppm in a 10,000-gallon pool or spa.
• 三氯/片氯: 1.5 oz. of trichlor with 90% available chlorine raises FC level by 1 ppm in a 10,000-gallon pool or spa.
• 二氯: 6.5 oz of Granular chlorine with 56% available chlorine raises FC level by 3.0 ppm in a 10,000-gallon pool or spa.

2. 准备对游泳池和水疗中心进行冲击处理 

1). Shut your SWCG if you have one. Please find out the volume of your pool in gallons and ensure the water is at its normal level. Take the FC reading. Knowing your current FCL will give you an idea of how much chlorine shock your pool or spa needs. The recommended range is 2-3 ppm for non-saltwater and 3-4 ppm for saltwater pools and spas. 

2). Test and know your Cyanuric acid level in the water. The correct range for non-saltwater is between 30 – 60 ppm, with the ideal level at 40 ppm, 70 ppm – 80 ppm for saltwater, and 20 ppm to 30 ppm for indoor pool and spa. The cyanuric acid level in your water should always be the main factor in deciding what amount of chlorine shock your pool needs.

3). For the FC level to be stable long after adding chlorine to your pool or spa, the initial chlorine dose when clearing cloudy water should raise the FC level slightly above the recommended levels. Add enough chlorine to raise FCL between 5-7 ppm for non-salt water, settling at 3 ppm for a 40 Cya level. Add enough chlorine to raise FCL to 6-11 ppm for saltwater and wait until FC reaches the recommended levels of 4 ppm for an 80 Cya level.

4)。由于我们建议使用液氯池冲击，因此，当 FC 水平下降时，请通过每天晚上测量和调整 FC 水平来将 FC 水平保持在建议水平。 

3. 如何在您的泳池和水疗中心添加液氯、颗粒氯或稳定氯

1)。对于次硫酸钠或液氯，您可以在泳池周围或浅水区均匀添加适量，以提高 FC 水平。  

2). For granular chlorine, ensure your pool’s pH and Calcium Hardness are a little lower because they will also rise. Prepare the treatment according to the instructions on the package. For Cal hypo, dissolve in water and mix well before adding to the pool or spa for faster results. Pour Cal hypo evenly around your pool or at the shallow end. If there is any undissolved shock left, add some pool water, mix gently, and pour it into the pool.

3). For trichlor and dichlor, ensure the Cyanuric acid level is a little lower because its level in the water will rise. Remember that the only way to reduce Cyanuric acid is to drain and refill your pool or spa water, and you must be very careful. Put chlorine tablet(s) at the skimmer to shock your pool, while dichlor can be added directly to the pool and spa. 

遵循本指南，您将提高水中游离氯含量，并净化浑浊的水质。请务必始终保持推荐的游离氯 (FC) 和氰化物 (Cya) 水平。 

If you put off your saltwater generator, ensure that FCL has settled between 3 – 4 ppm before putting it back on, and remember to reset both the SWCG percentage setting and your pump run-time as appropriate to maintain the ideal FC level.  

电击后泳池仍然浑浊吗？

If you are done shocking your pool and it’s still cloudy after 30 minutes, the problem could be something else, not low FC. Here are more detailed 泳池水浑浊的原因 以及有关如何清除顽固浑浊游泳池水的更多信息。
