First, read the English article below.

Use your brush to clean the bottom and sides of the pool again, then vacuum up all the dead algae. If there are a lot of dead particles and you're having trouble vacuuming them, you can add a flocculent to help the algae bind together and make it easier to vacuum. Your swimming pool water should be crystal clear after treatment. If the algae seems to be coming back, go through the shocking and treating process again until it's all cleared away. All chemical levels should be in the normal range. 

Now, please write a short abstract for it in Chinese. Abstract:
吸除遗留在泳池里的死藻。 运转过滤器，直到把藻类彻底清除干净。 用化学测试包再次检测池水的化学物质含量，所有指标值都应在正常范围之内。
