If you've filled your pool to capacity, check the unit's user manual to find out the maximum amount of water it can hold. If your pool is not completely full, or if you can't find its maximum volume anywhere, you can calculate how much water it contains using the following formulas: For rectangular pools: width x length x depth x 7.48USgal (28.3l). For circular pools: x radius x depth x 7.48USgal (28.3l). For oval pools: x width x length x depth x 7.48USgal (28.3l). For variable depth pools, find the unit's average depth using the formula shallow end depth x deep end depth 2. When doing your calculations, use this number in place of depth. For irregularly shaped pools, use the previous formulas to find the measurements of each individual section, then add them together to calculate the pool's volume. First, divide your pool's current PPM by the recommended PPM. Then, take the number behind the decimal point and multiply it by your pool's total volume. The remaining number shows how many gallons or liters of water you need to drain in order to properly dilute the pool. For example, if you have a 26,000USgal (98,000l) pool with a current PPM of 5,000 and a recommended PPM of 3,500, divide the former by the latter to get 1.43. Then, multiply .43 by the pool's volume to get 11,180USgal (42,300l) This is the amount of water you need to drain. You can do this by renting a pump for between $25 and $40 an hour or by purchasing a pump for anywhere between $100 and $1000, depending on the quality. Pumps are available from most pool supply and home improvement stores and typically come in 1 of the following forms: Submersible pumps, which sit completely inside the water and are usually more affordable than above-ground pumps. Above-ground pumps, which sit next to a pool and are usually faster and more powerful than submersible pumps. your pool. Hook your pump up to the pool by following the manufacturer's included instructions. Then, turn the pump on and drain the pool until you remove the amount of water necessary for proper dilution. In most cities, you cannot legally discharge pool water into a public area, so make sure to release the water into your yard or your house's sewer clean-out. So you can keep track of your drainage amounts, check your pump's user manual to see how much water it drains per minute. Your sewer clean-out is a small, circular hole covered by a miniature manhole cover. Look for it in the area immediately surrounding your house.

Q: Everyone gets a start somewhere, and a member of your local body art community might be able to put you on the trail of a good place to apply. Come prepared to every meeting with a professional: bring your portfolio and any other artistic accreditation you have earned. Even if the tattooist you inquire with can't help you, you can always ask for their professional opinion on your work. Maybe you have a flair for a certain style that their colleague is known for, in which case, their recommendation might go a long way. The avenues for gaining an apprenticeship are few, but by making your presence known at and inquiring for an apprenticeship with local tattoo parlors, you are likely to get some direction. If there is a tattoo parlor that you are particularly interested in apprenticing for, be respectful but persistent. Visit the parlor regularly with your art in tow and some small niceties, like coffee. Volunteer your time with cleaning or maintenance. Depending on the terms of your apprenticeship, this can last for three years and may cost thousands of dollars. You will need to support yourself during this time in addition to covering any additional expenses related to your education as a tattooist. The Alliance of Professional Tattooists (APT) recommends a minimum of a three year apprenticeship. Generally, after being accepted into an apprenticeship, you will sign a contract either agreeing to pay the tattooist a sum of money in exchange for the apprenticeship, or to work for the tattoo parlor for a number of years following the completion of apprenticeship. This will normally come in the form of a contract from the tattooist under which you will apprentice. This will establish the expectations of you as apprentice and the tattooist as the master artist. Read over the terms of this contract carefully and, if you are able, have a lawyer check it as well. Though you will someday, with enough practice and dedication, be a master tattooist in your own regard, during your apprenticeship, the beginning especially, you will mostly be doing menial tasks in the tattoo shop. You will also be expected to watch carefully as the artist works.
A: Talk to local tattoo artists. Apply for your apprenticeship. Take a second job. Get your apprenticeship agreement in writing. Understand your initial responsibilities.

Article: Combine the chopped onions, olive oil, garlic, cumin, oregano, chiles, cider vinegar, and salt in a blender or food processor. Blend the ingredients together at medium to high speed until a thick puree forms. Do not drain the adobo sauce from the chipotle chiles before adding them. You should pour the sauce into the blender along with the chiles. Spread the sauce into the bottom of your slow cooker. Place the beef on top of it, and pour the beef broth over the meat. Place the bay leaf on top. Coat the beef in the sauce by turning it a few times, dipping all sides in the sauce at least once in the process. Use a 5-qt to 7-qt (5-L to 7-L) slow cooker for best results. Cut the beef into several chunks, if necessary, to fit it into the slow cooker. If you want it done sooner, set the slow cooker to high and cook the beef for 6 hours. Resist the temptation to open the lid and peek at your meal as it cooks. Doing so releases the trapped steam, and that steam is partially responsible for cooking the meat. As a result, the overall cooking time can increase 15 to 30 minutes every time you open the slow cooker. Remove the beef from the slow cooker and place it on a cutting board or rimmed baking sheet. Use two forks to shred the beef into pieces, working from the outside in. While shredding the beef, you should also discard any fat. A rimmed baking sheet or cutting board works best since some of the juices inside the beef can run as you work with it. Without a rimmed surface, these juices can create a big mess. Transfer the shredded beef to a large bowl. Ladle a little of the cooking liquid into the bowl, mixing after each addition. Add enough sauce to keep the beef thoroughly moist, but do not add so much that the beef drown in it or becomes soupy. If you have some cooking liquid left behind after you coat the beef, you can fill a spare ice cube tray with it and freeze the liquid for later use. These cubes of barbacoa sauce can be used to flavor stocks, soups, gravies, and other dishes later on. If you are not ready to serve the barbacoa yet, return it to the slow cooker and switch the appliance to its "warm" setting. You can keep it warm using this method for another 2 to 4 hours. After that point, you should consider transferring any uneaten beef to airtight containers and storing it in the refrigerator. Reheat it in the microwave after refrigerator storage. The beef barbacoa is ready to eat. Serve it to your family or guests while still warm, and offer it with an accompaniment of tortillas, onion, cilantro, and salsa.

Puree the sauce ingredients. Layer the sauce, beef, and broth in the slow cooker. Cover and cook on low for 8 to 10 hours. Shred the beef. Mix the shredded beef with the barbacoa sauce. Keep it warm in the slow cooker. Serve.
