Do not remove the tensioner completely unless replacing it. Instead, pivot the spring-loaded tensioner away from the belt and then retighten the mounting bolt(s) to hold the tensioner in the loose position. Spin the tensioner pulley and listen for a rattle or humming noise that would indicate loose or worn bearings. Uneven wear at the rear of the old timing belt could indicate a misalignment between the tension pulley and timing belt due to worn bearings. If any indications of damage or worn bearings are found, replace the tensioner pulley. The permanently lubricated tensioner pulley bearing can become dry, worn, loose, broken or can freeze up, so the best practice is to replace it, if it's not new.

One-sentence summary -- Loosen the mounting bolt(s) holding the belt tensioner using any special cam holding tools, while following the service manual. Examine the tensioner pulley for damage such as dents or cracks.

Q: UV lights treat the single-celled algae that causes green water. The UV light is installed in the water. Water passes through the light and the algae gets destroyed. The light needs to be replaced yearly and brought in during winter months. Your pond may have a filter, which is useful for growing bacteria that breaks down waste and food when you have lots of fish. If it is difficult for water to flow through the filter, follow the owner's manual to clean the filter. Only use pond water so that you preserve the helpful bacteria in the filter. Plants are a way to naturally keep the pond clean and clear of algae. Plants such as anacharis, hornwort, and parrot's feather live under the water and keep the water full of oxygen, which limits algae growth. Lilies and lotus plants also cover the surface of the water, blocking sunlight that aids excessive algae growth. You introduce plants by planting them at appropriate layers. For example, submerged plants such as anacharis rests fully below the surface with its roots in a basket. Marginal plants, including cattails, and lilies are rooted in water with aquatic potting soil. Floating plants such as water hyacinths rest on the water's surface. Aeration adds oxygen to the water by churning it. Plants, waterfalls, and fountains all help, but you can also add an aeration pump to keep the water mixed, preventing algae and odors. Install small pumps by attaching the water recirculating hose and placing the pump in the water away from dirt, such as on a block or rocks. Hide the open end of the hose away from the pump near some rocks. Plug the pump's power cord into an outlet, making sure it is away from water. You may wish to bury the cord underground in PVC pipe. Uneaten fish food leaves nutrients that cause algae buildup. Either use higher-quality food or rely on natural food such as the algae growing on the pond liner. Don't offer extra food when it isn't needed. Monitor the water for leftover food and offer less as needed. Feed fish high-protein fish food, such as Pond Care Summer Staple, two to four times a day when the water is warm. Feed them once every day or two days with a low protein food when the water goes below 60 degrees F (15.5 degrees C). In winter, the air filter keeps bacteria alive that would otherwise die in the cold. In the summer, algae prevention can be bolstered by adding a product such as Microbe Lift. Follow the directions on the label for the correct dosage. Beneficial bacteria breaks down chemicals harmful to fish, such as ammonia, and food and waste nutritious to algae. It will also help balance the microbiome in your pond.
A: Install a UV clarifier. Rinse your pond filter. Introduce plants. Supplement aeration with a water pump. Control the amount of food for fish. Replenish bacteria in the summer.

Article: One of the easiest ways to cook beef you plan on shredding is to use a slow cooker. Depending on the size of the slow cooker, you may need to cut the roast in half to ensure that the entire thing will fit inside. For best results, use a 4-qt to 5-qt (4-L to 5-L) slow cooker. If you can fit the beef roast inside your slow cooker without cutting it in half, consider cooking it whole. Place the beef roast in your slow cooker and pour the beef broth over it evenly. If desired, you could add other ingredients to the slow cooker at this time to give the taste of the beef more depth. For instance, you could add up to two onions, cut into wedges, and two cloves of garlic, minced well. Place any aromatic ingredients like these on the bottom of the slow cooker and sit the beef on top of them. Cover the slow cooker and slowly cook the beef roast until the beef is tender enough to peel off using nothing more than a fork. If you have enough time, try cooking the beef on low for 11 to 12 hours. Doing so will make the beef even more tender than it will be when cooked on high. The beef will be well-done. If you use a cooking thermometer to check the internal temperature of the beef roast, look for a temperature between 160 and 170 degrees Fahrenheit (71 and 77 degrees Celsius). While a slow cooker is one of the simplest kitchen appliances you can use to cook beef for shredding, this is not your only option. If you do not have a slow cooker or prefer another cooking technique for roasts, you may cook the roast using an alternate technique. Another simple way to cook beef roast is to slow cook the roast in the oven. Similarly, you can cook the beef roast on the stove using a Dutch oven.
Question: What is a summary of what this article is about?
Cut the roast in half, if necessary. Combine the roast and the broth. Cook on high for 5 to 6 hours. Consider alternate cooking methods. Finished.

Article: If your thermostat is set to a high temperature, your gas bill is bound to be expensive. Try lowering your thermostat a few degrees to reduce your bill by 5-10%. For instance, turn the temperature from 70F (21C) to 68F (20C). Don't keep the heat on in your home when it's not necessary. Turn off the heat when you're at work or gone on the weekends. The energy saved will reduce the cost of your gas bill. Some areas in your home need to be warmer than others. For example, it may be important to you to keep the main floor warm, while the basement can be a bit cooler. You can control the heat by installing radiator valves on every radiator in your home. These self-regulating valves allow you to control the temperature of each room by adjusting the amount of hot water goes to the radiator. Personal, or space, heaters use up a lot of energy. Plus, they are an inefficient way of warming up large areas. Avoid using them and instead look for more efficient ways to keep warmlike improving your home's insulation. If you want to warm a small space only, a personal heater may be more effective than heating the whole home with a furnace. Choose a radiant heater, which are more energy-efficient than other models.
Question: What is a summary of what this article is about?
Lower the thermostat. Turn off the heat when you're not home. Save energy with radiator valves. Reduce the use of personal heaters.
