In one sentence, describe what the following article is about: When the pH of pool water gets too high, it prevents chlorine from being effective, meaning it can't prevent or treat an algae bloom. Add pool water to a test kit and test the pH of the water.  Lower the pH by adding muriatic acid or sodium bisulphate. Increase the pH by adding sodium carbonate.  Test the water again after treating it. The ideal pH is between 7.2 and 7.6. Black algae especially are very resistant to shocking and algaecide, so you must brush the algae before treating the pool. Brushing breaks up the protective slime layer that grows on the outside of the algae. Brush the bottom and sides of the pool thoroughly and vigorously to break through the algae's protective layer. Like green algae, the best course of action to treat mustard and black algae is to add shock and algaecide. Immediately after brushing, triple shock the pool by adding 3 pounds (1.36 kg) of shock per 10,000 gallons (37,854 L) of water. During the shocking and algaecide treatments, leave the pump and filter running all the time. For mustard and black algae, it's important to use copper-based algaecides. Ammonia-based ones will not be effective against these types of algae. Use an algaecide with at least 30 percent active ingredient, and you may want to go as high as 60 percent. After adding the algaecide, let it sit overnight. Continue brushing the entire surface of the pool every day for the next seven days. This will make sure the algae's protective layer gets penetrated with shock and algaecide, which will ensure the treatment is effective. After three to four days of daily brushing, shock the pool a second time with a regular shock quantity. Add 1 pound (454 g) of shock per 10,000 gallons (37,854 L) of water. This will guarantee the chlorine has enough strength to kill the algae. After shocking the pool again, continue brushing daily for the next three or four days, or until the algae is gone. Once the algae are dead, vacuum the pool thoroughly to remove all the dead plant matter. When the pool has been vacuumed and the water is clear, clean the filter. Rinse the cartridge, backwash the filter, and clean the filter with filter cleaner.
Summary: Test and adjust the water pH. Brush the sides and floor of the pool. Shock the pool. Add algaecide. Brush daily for a week. Shock the pool again. Vacuum and clean the filter.

In one sentence, describe what the following article is about: Good customer service is often considered quick, effective, and appreciative. Thus, you should make every effort to respond to a customer’s email as soon as you as acquire all of the necessary information.   The best response time is between 24 hours and three days. Anything longer than that, the customer will question whether you received the email or if you simply do not care. In today’s society, customers are conditioned to receive immediate responses to their questions, thus a quick reply can build customer confidence and, in return, become a competitive advantage. Subject lines are important because they often determine whether an email is opened to be read or not. A blank subject line is most likely to get deleted or lost frustrating the customer who has to open the email before knowing what it is about.   Keep the subject line brief and specific, and place the most important word at the beginning. Remember that most email subject lines only allow 60 characters, while a mobile phone shows just 25 to 30 characters. Placing the most important word first to draw immediate attention to the email. Be careful not to use all capital letters or excessively use punctuation, like exclamation points. Both are perceived as yelling or excitement and not appropriate for a customer service emails. Customers appreciate personalized emails that are addressed to them by their name. This proves that they are not just a number and, instead, indicate that you appreciate their business by being respectful and polite.   A personal email will make a stronger connection with the customer than an informal, generic email. Choose a salutation that reflects your customer’s status. For example, a medical doctor should be addressed as “Dr.” If unknown, simply use the standard “Mr.” for men and “Ms.” for women. Similar to using the customer’s name, you should also use your name to personalize the email. After all, this should be framed as a conversation between two people rather than a transaction between a business and a customer.  In addition to your name, include your title and contact information so that you establish some rapport for future communication.
Summary: Make an effort to reply quickly. Customize the subject line. Personalize the email by using the customer’s name. Introduce yourself.
