In one sentence, describe what the following article is about: With small fish tanks, you must do fifty percent or larger water changes at least twice weekly but preferably every other day. Without massive, frequent water changes, the tank can destabilize and put your fish at risk. Thus, it is important to schedule time to do your fish tank water changes and cleaning. Every other week, perform deep cleanings in which you remove decorations and scrub the interior.  Observe your fish daily to see whether they look healthy and are behaving normally. Do they have good color, clean scales, unclamped fins? Or are they slimy and ragged? Remove any dead fish. If your fish look sluggish, stressed, or they are gulping for air, do a water change.  It is not beneficial to perform deep cleanings too often, as you will remove essential bacteria. Make a checklist to ensure that you have all the necessary supplies. Having your supplies on hand will speed up the process. Most supplies are available at pet or home goods stores. Use this list to help you.  2 fish nets Temporary fish tank or container Fresh water in the quantity you want to replace Algae pad New toothbrush 2 large buckets (5-10 gallons) Gravel vacuum Siphon Water conditioner Aquarium-safe glass cleaner or a vinegar-based solution Clean cloth Towel Place tarps or towels on the floor to catch any spilled water. Keep the tank in place. Do not move your tank or tip it into the sink. Juggling your fish puts them under stress and stirs debris in the tank. Wear a short-sleeved shirt or tank top. You might consider wearing a bathing suit. Aprons also can protect your clothing. Wearing water-resistant shoes like water shoes or flip flops is also a good idea. If applicable, unplug the aquarium’s aerator, filter, and heater. Leave hood lights plugged in. Place the hood behind the tank to illuminate the tank.
Summary: Schedule time to clean your tank. Gather cleaning supplies. Prepare your work space. Dress appropriately. Unplug electrical devices.

Problem: Article: Being cheerful isn’t something that’s going to just come about by wishing it. To spread cheer to others, it will be necessary to actually love your life. This means finding and practicing activities that you’re passionate about.  Make a list of times in your life when you were deeply happy. Include as many details as possible. Include who you were with at the time, whether you were indoors or outdoors, what activities you were doing, and perhaps even what the temperature was like. These details will be different for everyone, so it’s important to flesh out all those details. Then, look for trends in the details. Have you been most happy when you’re outdoors in nature? Or is it when you’re surrounded by people who challenge you? Notice which conditions produce the most happiness. Then, work on sharing these conditions with other people. Maximize the time you spend under those circumstances. Before you know it, cheerfulness can become natural to you. If nothing comes to mind when you think about your passions, this may take some time and effort on your part. Rest assured that everyone has the potential for passion. Experiment with many activities and situations until passion starts to emerge. Becoming cheerful requires being comfortable with yourself. You are a unique person with your own individual traits, strengths and challenges. Be proud of your abilities and strive to be happy about who you are. Avoid striving for perfection. Instead, think of yourself and your life as works in progress. This can make it easier to accept yourself. Humans are complex. Even people who appear cheerful most of the time experience a broad range of emotions throughout any given day. Don't try to force yourself to feel happy all the time.  Sometimes, you might realize that being cheerful just isn’t something you’re capable of at the moment. There's nothing wrong with that. What’s most important is that you learn to accept your emotions. Learn to work with what you feel instead of trying to focus only on those emotions that you consider most positive. For example, if you are angry at someone, don't try to reject those feelings because anger is "bad." Instead, accept your anger, and think about what you can do to feel better or forgive the person. If you're having a bad day, acknowledge it. You shouldn't just ignore the fact and continue trying to act happy. Then, after you've accepted the fact that you're experiencing a bad day, look for positives and think of ways to make the situation better.  For example, imagine you've been laid-off from your job. That's probably upsetting for you, and it's okay to accept that. But, after the initial shock has passed, start thinking about ways to improve your situation. Make a plan to apply for unemployment, and for finding a new job. Perhaps this will be an opportunity to find work you like better. This will help you accept the complex nature of life. Faking cheer can be counterproductive. People will likely be able to pick up conflicting messages in your body language and facial expressions. So, it’s best to just let any emotions flow through you, whatever they might be. At the same time, don’t brood over a particular emotion, but instead try to learn why you are feeling it. For instance, if you are angry, that might be because you’re uncomfortable and don’t know how to express it. Or, you might have unrealistically high expectations for the situation you happen to be in. This might not be easy at first. But, by persistently trying to relate your emotions to what’s the present moment, you can learn to control them. Negative experiences can have lasting impacts on our brains work and our ability to control our emotions. This includes traumatic events and long periods of depression.

They will also provide helpful practices or strategies for working through difficult emotions. If you can, don’t be afraid to experiment with different counselors. Sometimes it takes a while to find one who is the right fit for you. Many health insurance plans provide for a certain number of mental health visits. Check to see if yours does. Journaling has many mental health benefits that can help you feel comfortable with your past. Especially if you have traumatic events in your past, try writing in about your feelings in a journal every day.  Writing about your past experiences or negative emotions is a particularly useful method for working through past traumas. Sit down and write down as many details as you can remember about the experience you have in mind. Or, just describe the emotions you are feeling in the present moment. Writing about your emotions and negative past experiences can give you some distance from them. It can also make them manageable for you in future situations. If you find this overwhelming, or it is upsetting you more than it is helping, you may need professional help. Consider talking to a counselor or therapist. Meditation and/or breathing exercises can also help you control emotions related to your past. Some psychologists have called this developing "mindsight."
