Problem: Article: Use a water siphon to remove the water. Reach the end of the siphon hose to the bottom of the tank and squeeze the pump to drain the water. Pour the removed water into a bucket. Dump the water down a drain once you are finished.  Water siphons can be purchased at pet stores or online. Never prime the siphon by sucking through the hose with your mouth. Only add a little water at a time since drastic salt adjustments could affect the health of your fish. Pour the solution slowly throughout the entire tank so it is not localized in one spot of water. Let the solution you added thoroughly mix into your tank for 1 to 2 hours before you test the salinity. Use a hydrometer to check the specific gravity in your reef tank. It should be around 1.025 for a healthy reef. Each time you add the solution to your tank, wait 1 hour before testing the specific gravity. Testing too quickly or adding too much water in a short period of time will shock any marine life you have.
Summary: Remove 10% of the water from your tank. Add 1⁄2 US gal (1.9 L) of the solution to your tank. Check the specific gravity after 1 hour. Continue adding 1⁄2 US gal (1.9 L) until you reach the desired salinity.

Problem: Article: As soccer is a year-round sport, you will have many occasions to follow matches on screen. Follow one or several of the top European leagues, as the world’s most entertaining soccer games are played in these leagues. Alternatively, find out which leagues are televised at a convenient time of the day for you. You can also start by watching soccer with your friends or other locals in pubs. Watching games together with other people will give you a lot of energy that will easily trigger your interest in the sport. Each country’s league has its own characteristics and styles of play. Find out which align with your own tastes. It will help to watch games from several countries to get a feel for the contrast in styles. Start by watching the top five European leagues.  The English Premier League is known for its physical, fast-paced style of play with higher scoring. Italy's Serie A is known for being technical with possession-based defensive styles. Spain’s La Liga is known for quick passing, with scoring levels in between the English and Italian leagues. It also has two of the most exciting teams in the world, Real Madrid and FC Barcelona. Germany's Bundesliga is known both for physicality and technique, with stronger teams through the middle of the table. France's Ligue 1 is a solid step below the other four, but with some big spenders in Paris Saint-Germain who are entertaining when in their stride. USA and Canada’s top league is a good option based on your timezone. While the level is not as high as in the European leagues, the games are often fast, physical and the fans are not as snobby. Following local games can help you better understand the grassroots appeal of the game which underpins all of the big money and glamour of the international scene. Being there and experiencing the games in person offers valuable lessons on the true feeling of the sport.
Summary: Start watching games on TV. Get informed about the different leagues. Watch the MLS. Go to local games in your hometown.

Problem: Article: Whenever you're trying to lose weight, it's important to weigh yourself regularly.  You'll be able to see your progress and determine how well your diet is working.  Weigh yourself about one to two times per week.  Hopping on the scale each day doesn't show you the most accurate progress overall.  Daily fluctuations in weight (either a gain or loss) are normal and might not reflect your true overall progress.  For the most accurate trend, weigh yourself at the same time of day, on the same day of the week and wear the same clothes (or wear no clothing). Regular weigh-ins have also been shown to help prevent weight-gain. Keeping a food journal has been shown to help people succeed with weight loss.  Jot down all your meals and snacks.  It's harder to fall off track if you know you you'll need to document everything. You can purchase a journal or food journaling app. Track as many days as you can. Check in with yourself every month or two to reevaluate your progress.  Consider how much weight you've lost and how this diet has worked for you. Again, a diet low in vegetables may be cause for slower weight loss.  If you're doing well, losing weight and enjoying the diet you've adopted, keep going until your goal weight. If you notice your weight loss has slowed or stopped, take a step back and reevaluate your lifestyle.  Being more diligent with your food journal can help see if there's any areas where you've slipped up or are eating more than you should.
Summary: Weigh yourself weekly. Track your meals and snacks with a food journal. Reevaluate your progress.
