Problem: Write an article based on this summary: Use a combination test strip to test your water every week. Add fresh, dechlorinated water whenever the level drops 12 inch (1.3cm) or more. Change out Put the filter on a timer.

Answer: Combination test strips test for ammonia, nitrite, and phosphate levels at the same time, making testing quick and easy. Simply put the test strip in the water for the designated amount of time and then compare the colors on your strip with the chart supplied with the test strips. This is best for tanks that seem to be functioning well. If you are trying to diagnose a problem, it's a good idea to get individual tests that will give you more detailed results. When the water level drops due to evaporation and no saltwater is removed, adding more salt water would over-concentrate the tank. Instead, simply add dechlorinated fresh water to keep the salinity level steady. Adding water as the level drops will keep your tank healthier and will reduce maintenance. In some areas with high levels of other impurities, or especially sensitive aquarium residents, reverse osmosis, deionized, distilled, or otherwise purified water can help avoid adding copper and other harmful minerals to the tank. some of the tank water on a weekly or biweekly basis. Even with a low maintenance tank, it is important to change some of the water on a regular basis. Aim to either switch out 20% every other week or 10% every week. This will be easier on the animals and plants in your tank than a larger percentage change. Doing weekly or biweekly small water changes will require less work than a higher percentage change because you will not have to remove any plants or animals from the tank while you do the change. This will help ensure that your filter feeders don't have to fight the machine. Filter feeders let their morsels come to them slowly. If a mechanical filter will stay wet when it is turned off, you can put it on the lighting timer so it only comes on at night. Some wet-dry filters do not include (or can be used without) a mechanical filter, such as a sponge. They can constantly aerate and bio-chemically filter water well without removing particulates too efficiently. Their constant operation might be more important for big fish. There should always be something moving the tank's water, such as a powerhead, to keep the food moving enticingly so the fish can hunt it. It also keeps the live rock and sand biologically filtering the water.

Answer: Scissors are a good method for shortening a beard, but require a skilled hand for finer details, such as thinning or shaping. Make sure the scissors are rust-free and without major imperfections or notches in the blades that may tug on or pull your hair. Don't use kitchen scissors or garden shears. These can be too big and clumsy to maneuver. You don't want to cut yourself. This will prevent you from cutting the hair too short. Try to imitate the way a barber gathers hair in a comb, then lightly clips it. Comb from your ear to your jaw, exposing a tiny amount of hair. Trim any hair which is on the outside of the comb's teeth. Use caution when performing this step. Begin by trimming very short lengths of hair - you can easily decide to trim more, but it is impossible to correct the mistake if you accidentally trim too much. Continue cutting the beard evenly until you've reached the desired length. Comb the beard again to ensure you've got an even trim of the hair. Comb the hair straight down. In a straight line, trim any hair that falls below the line of your lip. Using extra care, use the scissors to trim the hair as close as possible on your neck. If possible, use an electric trimmer for this step. If you're intimidated, you can simply lather and shave your neck with a safety razor to remove all the hair. This can be much easier than making the finishing touches with scissors.

Problem: Write an article based on this summary: Take it to a coin sorting kiosk. Roll your coins for your bank. Purchase your own coin sorting machine.

Answer: The most convenient method for cashing in your change is to simply take your jar of coins to a machine that will sort the change for you and distribute your cash. These machines, like Coinstar, are usually found in grocery stores, malls and other retail locations. You simply pour the coins from your jar into the machine and it will then convert it into cash. The main downside to kiosks like Coinstar is that they take a significant cut of your cash in service fees -- roughly 9 cents to every dollar you have collected. Some banks will give you cash for loose change, but you have to sort the change into each category (pennies, nickels, dimes, quarters) before they will do this. You can get these rolled tubes from your bank, but you will have to take the time to sort and roll them yourself. Be sure to check with your bank beforehand to make sure they will cash rolled coins from you. Some banks do not cash loose change. Other banks will accept rolled coins, but they will charge a fee to cash them. If you don't want to sort all the nickels, dimes and pennies yourself, you can look into buying your own coin sorting machine, which generally cost between $25-$35. These machines will sort your coins and then put them into the appropriate roll for you to take to the bank. You might not want to invest in this kind of machine when you are first starting to collect coins. If you only collect $15 in change in one year, it won't be worth even the price of the coin sorting machine.

Problem: Write an article based on this summary: Understand that the nutrients in most formulas are similar, but their sources can be different. Identify lactose in cow's milk formulas. Know that some formulas are made from soy. Understand the ingredients used in organic formulas. Be aware of probiotics used in some formulas. Look out for other ingredients that are often included in formulas.

Answer:
All baby formulas are regulated and, in general, every baby formula contains basically the same combination of protein, fat, carbohydrate, vitamins, and minerals, which closely mimic that of human breast milk. The difference between the formulas is the sources of the proteins and carbohydrates that are used. There can also be some variation in the sources of the other main components. Some parents may prefer not to feed their baby a formula that has a particular nutrient source, such as corn syrup, while others have no problem with it. Since the nutritional value is basically the same for all formulas, knowing about nutrient sources is a useful way to differentiate between baby formulas. Breast milk and formulas made from cow's milk have the same main carbohydrate, which is lactose. However, there are lactose-free and soy formulas for babies that are lactose intolerant or being raised as vegans. These, and other specialty formulas, contain various types of carbohydrates that might include sucrose, modified corn starch, corn maltodextrin, or corn syrup solids. Most formulas have cow's milk as a base and whey and casein are their proteins, but some other formulas are made from plant proteins and have a soy base. These proteins have a soy protein isolate that is easier for some babies to digest. Soy-based formulas are often fed to babies who suffer from allergies or digestion troubles when fed formulas with a cow's milk base. Vegetable based formulas are also popular with vegans because they want to avoid products that come from animals. The ingredients in organic formulas are sourced from organic produce and organic dairy. These ingredients are obtained without the use of chemicals such as pesticides, herbicides, and growth hormones. Some people believe that organic ingredients are more healthy for developing babies, and limit their exposure to harmful chemicals. Probiotic formula is formula that includes good gut flora, microorganisms that are meant to promote healthy digestion and regular bowel movements. Generally, these formulas are given to babies who suffer from diarrhea or generally weak immune systems. These bacterial cultures can strengthen the body's immune response and soften stools. The regulations for baby formula are strict about the nutrients that must be in the formula in order for the baby to grow and develop properly. However, these regulations do not restrict the addition of "other ingredients". Various brands add these ingredients for various reasons. One ingredient that is often added is various types of different nucleotides, which are supposed to help with the development of the immune system. These added ingredients are safe for the baby to consume and may help them develop, but they are more likely a way for the different brands to make their formula stand out.
