INPUT ARTICLE: Article: 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: The default font size for most word processing applications is 12-point. If you've edited the content of your resume as much as possible and you still need to cut some space, consider lowering the font size to 10.5 or even 10. Avoid going any smaller than that, however, because it will make your resume hard to read. Make all the text in your resume the same size, rather than having the names of employers or schools larger than the rest of the text. If the labels or headings for the sections of your resume are larger than the rest of your text, you can also experiment with making them smaller. Try making them the same size as everything else. A good resume uses white space to break up text and allow for easy scanning. However, too much white space can push your resume over one page. You can adjust the line spacing in the text formatting menu on your word processing app. Decrease line spacing by the smallest increment possible. Make sure your words don't overlap and can still be read. You may want to print out your resume and see how it looks. Most word processing apps default to 1in (2.5cm)margins all the way around. However, you can typically get away with decreasing those margins to give more room for the text. Test your document by printing it before you send it to the potential employer to make sure it prints okay. Particularly if you're emailing your resume, there's a good chance your resume will never be printed on paper. However, you still want to make sure it's printable if necessary. Your word processing app defaults to a single column. However, it's possible to create 2 or even 3 columns on a document. If you're finding it difficult to get your resume down to a page, you may be able to use a 2 column or 3 column layout to get more information on the page. If you want to use multiple columns, you're better off starting a new document rather than simply converting the document you have. You'll have an easier time arranging your information correctly.
Summary:
Decrease your font size to no less than 10-point. Tighten up the line spacing. Cut your margins in half. Experiment with multiple columns.
