If you're not ready to use your cored pears just yet, place them in a bowl of cold water with a few slices of lemon. This will prevent them from oxidizing and turning brown.

summary: Stop pears from turning brown.

Once you've washed and moisturized your afro, you don't need to do much more to style it. Avoid styling products and blow dryers as much as possible. Prevent frizz by always wrapping your hair in a silk scarf before bed. This will help ensure that your afro keeps looking good without the need for heat styling or additional products. If you want a fuller afro, you should comb it after applying your moisturizer. This will help detangle your curls and make your afro nice and full. Be sure to use a wide-toothed comb or an afro pick instead of an ordinary hair comb. Be very gentle while combing. Work in small sections and run the comb from the root of the hair to the ends. Combing every day is not a necessity, especially if you have a shorter afro. Avoid combing more than you need to in order to get your desired volume, as over-combing will just cause damage. If you're a woman, consider adding some extra style to your afro with adornments like clip-in flowers, headbands, or scarves. You can use simple accessories or bold ones, depending on your own personal style. If you want to switch up your look, a faux hawk can make your afro look extra stylish. This works especially well with medium-length afros. Use a hair gel or similar product to slick back the sides of your afro, leaving the top free. You can also get cornrows on both sides of your head, leaving just the top of your afro loose.

summary: Go natural. Comb your afro. Add some adornments. Consider a faux hawk.

Summarize the following:
To lower both total alkalinity and pH, you will need to add an acid. Liquid muriatic acid (hydrochloric acid diluted to 20 percent) and dry sodium bisulfate are among the most popular choices. The acid combines with the water, thereby increasing the concentration of hydrogen ions and lowering the pH. Similarly, the acid reacts with bicarbonates in the water and reduces the water's total alkalinity in the process. You could also look for a generic "pH decreaser," "alkalinity decreaser," or "combination decreaser" chemical at a pool supply store. The pH will drop faster than the alkalinity, so you need to fix the alkalinity first. Once you balance the alkalinity, the pH will gradually adjust to it. Always follow the instructions on your pH/alkalinity chemical when preparing the correct amount. As a general rule, you will need 1.6 lbs (725.75 g) sodium bisulfate or 1.3 qt (1.23 L) muriatic acid for every 10,000 gallons (37.85 kL) of water to drop the total alkalinity by 10 ppm. Scoop water out of your hot tub into an 8 gal (30.28 L) plastic bucket until that container is three-quarters full. Pour the full amount of pH decreaser into the water in the bucket and let it dissolve. You must add the acid to the water. Pouring the acid into the bucket first and adding the water can cause damage to the bucket and may result in ineffective mixing. Make sure that the pump and filters are running. The hot tub should be set at its usual temperature and speed before you continue. It is crucial, however, that no one is in the hot tub while you are balancing the water. Slowly pour the diluted decreaser into the center of the hot tub. Pour the acid in gradually instead of dumping it in all at once. Adding the acid too quickly can cause damage to the sides, bottom, and equipment in the hot tub. Allow the pump to circulate the water for three to six hours after you add the decreaser. During this time, the pumps should circulate the water and acid together more thoroughly. Only after the two have been well combined will the pH and alkalinity be consistent throughout the hot tub, and you need to wait until these measurements are consistent before moving on any further. Test the alkalinity first, then the pH. If done correctly, the alkalinity should already be balanced. The pH may not be balanced yet, however. If either the alkalinity or pH is still high, repeat the process. Continue as needed until the water is well balanced. You should completely drain the water in your hot tub at least once every four to six months. Afterward, fill the hot tub back up, balance the pH and alkalinity as needed, and continue to monitor the conditions as usual. You will need to balance the pH and alkalinity of your water nearly every week if you use the hot tub regularly. Adding chemicals to the water so often can cause excess build-up, and you will likely notice that it is becoming more difficult to balance your water conditions. Once you notice this difficulty, it is time for you to change the old water out for fresh water.
summary: Choose the right chemical. Determine your initial measurements based on total alkalinity. Mix the chemical together with a small amount of water. Turn the hot tub on. Add the diluted chemical to the hot tub. Give the water a chance to balance. Test the alkalinity and pH again. Periodically drain the water.
