One advantage of a saltwater swimming pool over a non-saltwater pool is that you don’t need to manually measure and adjust the free chlorine level (FCL) by adding harsh chlorine.

一个 盐水氯气发生器 （SWCG）产生氯并向您的水中添加适量的氯以维持建议的FCL。 

然而，海水泳池的一些潜在问题是游离氯含量过低或过高，以及 缩放 pH 值.

Chlorine demand in a pool depends on several factors, such as water temperature, room temperature, seasons, and pool activity. it’s therefore essential to regulate the amount of chlorine your saltwater generator produces and adds to your pool.

为了避免泳池出现 FCL 问题，请至少在几天后使用 可靠的化学测试套件.

然后，您应该根据读数调整 SWCG 中的百分比设置，以增加或减少 FC 级别。

氯气发生器只能在您设定的设置下工作。测试 FC 水平的频率应根据本文前面考虑的因素来确定。

For a practical example, if your pool is very busy with many swimmers, your pool will need more chlorine than a less busy pool with few swimmers.

因此，请根据泳池或水疗中心的氯需求量，定期调整氯发生器的百分比设置（低或高）。

Can I manually add harsh chlorine to my saltwater pool?

盐水氯发生器旨在产生少量氯，但始终保持水中理想的游离氯水平。

您可以通过调整百分比设置来增加或减少水中的 FC 水平，从而调节 SWCG 产生的氯量。

但是，假设你有 浑浊的水, 藻类， 或者 氨 in your pool. In that case, your chlorine generator cannot produce sufficient chlorine to clear your water or kill algae and ammonia, especially when your SWCG has reached a very high percentage.

In such a case, you must switch off your saltwater generator and manually add harsh chlorine to clear cloudy water, eliminating algae and ammonia. Then, when FCL is stable, you must put SWCG back on.

如何解决海水泳池中游离氯含量过高或过低的问题

As indicated earlier, you need to measure and adjust the FC level in your water by adjusting the percentage settings in your saltwater chlorine generator.

您为盐水发生器设置的百分比越高，水中产生的氯就越多，FCL 的读数就越高。

You only need to raise FCL when it’s low or reduce it when it’s high, and you should do that in the percentage settings of your chlorine generator after taking the FC reading.

As such, only adjust your SWCG after measuring and knowing the level of FC in your water.

调整 SWCG 百分比设置

要了解正确的 SWCG 百分比设置，以便为您的泳池产生理想的氯含量，您必须遵循以下几个步骤，它们是：-

1)确定泳池合适的 FC 水平。水中的 FCL 与氰尿酸水平密切相关。 

2)测量水中的实际FCL，并将其与SWCG中相应的FCL进行比较。FC水平测试应在晚上进行。 

3)。如果水中的 FC 水平较低，则增加 SWCG 的百分比以产生更多的氯，如果 FCL 较高，则降低百分比。 

4)。如果 FC 水平在一小时内未达到平衡，请等待 48 小时并重复步骤 2 和 3，直到 FCL 与水中的氰尿酸水平达到平衡。

海水泳池FCL值过高的原因

FCL tends to get high in indoor pools, where the pool is not very busy, and room temperature and water temperature are relatively lower, but the percentage setting in saltwater chlorine generator and pump run-time are set too high, ending up with more chlorine production and high FCL in the end.

To reduce your FC level, reduce the percentage setting of your saltwater generator and pump run-time, which could be high.

To avoid a high FCL problem, measure your FCL frequently and adjust the percentage of your SWCG and pump run-time to regulate the amount of FC in your water.

海水泳池FCL低的原因  

另一方面，如果您的海水池中氯含量低，您就没有按要求调整 SWCG，而且百分比太低，无法产生足够的氯来补充水中使用的氯。

经常测量水中的 FC 水平，特别是在泳池频繁使用后和炎热天气期间，并通过增加 SWCG 的百分比设置来调整 FCL，以避免水浑浊、藻类或氨。

 If you can’t raise your FCL by adjusting the percentage of your chlorine generator alone, try increasing your pump’s run time, too.

如果无法提高 FC 水平，并且 SWCG 百分比和泵运行时间都非常高，则您可能需要快速解决四个问题，它们是：

1. 氰尿酸过量： Cyanuric acid (a chlorine stabilizer) is potent and consumes FC if it is high in your water, causing high chlorine demand.

Measure and adjust your Cyanuric acid (Cya) level as required. The Ideal level of Cya for a saltwater pool is between 70 – 80ppm and should stay within that; otherwise, you will have a low FCL problem. View this 氯/氰尿酸图表 并了解给定 FCL 中的正确 Cya 水平。 

测量泳池中的氰尿酸 (Cya) 含量，如果含量过高，请排出部分泳池水并重新注水以降低其含量。除了反渗透之外，这是降低泳池中氰尿酸含量的唯一实用方法。  

2. 藻类的早期阶段： 藻类滋生的早期迹象是泳池中 FC 含量低。为了确保藻类问题得到解决，请进行 隔夜氯损失测试 （OCLT）。

OCLT is simply adding a specific amount of chlorine in a pool in the evening and taking the FC reading in the morning to establish the amount of FC used at night.

如果早上 FCL 下降超过 1ppm，则说明您正在处理幼藻，您需要 手动对泳池进行冲击 关闭 SWCG 后，因为它无法产生足够的氯来净化您的水。

3. 氯胺或氨: High chloramine levels cause cloudy water with low FCL. If you have ammonia in your pool, chloramine levels will be very high in your water and will require a lot of chlorine to get rid of.

游泳池中氨的迹象是水质极其浑浊、结合氯含量高、氰尿酸含量低、FC 含量低以及水中氯需求量高。

就像消除氯胺和藻类一样，你需要关闭 SWCG 并 手动冲击盐水池 使用强氯气去除游泳池中的氨。

4. 盐细胞中钙的积累： Chlorine is produced in the salt cell of a Chlorine Generator. However, since Calcium is used in chlorine production, Calcium scales always form and accumulate in the salt cell plates, hindering sufficient chlorine production and leading to low free chlorine levels in your pool.

To avoid Calcium buildups in your chlorine generator’s salt cells, you must regularly 检查并清洁盐电池板 当您看到泳池中有白色钙片或水垢时，应避免氯产量低。
