Pushup position requires you to rest your palms on the floor shoulder width apart, and in line with your neck. Place your feet together and bend your toes so that they are pushing you forward. Keep your back and legs stiff and straight. Push up from the floor so that your arms are perfectly perpendicular to the ground. It's best to do pushups on a gym mat or carpeted area. You can use your left or right hand, since you'll be alternating the hand you have on the ball as you continue the exercise. The ball should be located just to the outside of, or just beneath, the shoulder of whatever hand you choose to place on the ball. For instance, if you're placing your right hand on the ball, the ball should be located just to the right of your right shoulder. If placing your left hand on the ball, it should be located just to the left of your left shoulder. The arm corresponding to the hand you have on the ball will be exercised through a larger range of motion than your other arm. The arm that is not touching the ball should be at about a 90 angle. Lift the hand of that arm up and across your body to rest on the ball. Move slowly to ensure the ball doesn't roll suddenly. You will probably need to adjust the position of the hand that is already on the ball to make room for your other hand. As you bring the hand that is not on the ball up and across your body, shift the position of the hand that is on the ball so that it rests just to the side of center. When both hands are on the ball, your thumbs should be on the topmost spot and your fingers should be splayed out around the sides of the ball. Now, leaning both hands on the medicine ball, you need to move the opposite hand (the 1 that was on the ball to begin with) down to the mat, while keeping the other hand balanced on the ball. For instance, assume you started with your right hand on the ball, and have moved your left hand over to the ball, and are now leaning against the ball with both arms extended. Your next move is to carefully take your right hand off the ball and shift your left hand to the top-center of the ball to maintain balance. Using the prior example -- moving your left hand onto the ball, then moving your right hand off the ball -- place your right hand about shoulder width away from the ball. Your position should mirror the position you were in when your left hand was on the mat and the right hand was on the ball. Gently lower yourself down so that your right arm bends at about a 90 angle. Repeat for as many reps as you like.

The bucket may be placed anywhere, so long as the top of the bucket is below the bottom of the tank. If the tank is very large, additional tubing and coupling(s) may be required. Cut off any excess tubing, if desired. Begin by placing the vacuum end (the larger opening) of your tube inside your aquarium. You will want to keep the end of the siphon tube several inches above the gravel. Take the opposite end of your siphon tube, and point it toward your bucket. If the siphon you are starting has a "gravel vacuum" attached to it, you can rest the open end on top of the aquarium gravel. Place the vacuum opening (the larger tube opening) into the fish tank, so that water displaces the air in the tube. Then, slowly lower the remaining length of tubing into the tank. (Water should continue to displace the air from the entire length of the tubing.) If done correctly, there will be very little air left in the tubing. Grab the discharge opening (the other, more narrow end of the flexible tube). With the vacuum opening still submerged, seal the discharge opening by pressing a finger over it. Do not break the seal. Lift the end of the tube with the discharge opening up and out of the tank. Lower it down into your bucket, maintaining the seal. Make sure the vacuum end is still against the tank bottom, and remove your finger from the discharge end of the tube. Water will begin to flow from the tank into the bucket. Keep the discharge end directed into the bucket, while you gently move the vacuum end around the tank bottom. It may be useful to have a second person on hand to help you. When you have removed enough water, you can stop the water flow by raising the discharge end to a point slightly higher than the aquarium. You will need to flood the vacuum and tube again if additional siphoning needs to be performed.

Laundry soap is highly concentrated, and a little bit goes a long way. If you use too much, the residue can congeal on the fabric, making the fibers stiff and scratchy. Try using less detergent than you normally would. Too much detergent residue can also foster mold and bacterial growth especially if a towel stays damp for a while. If the chamber is too full, it might be keeping your towels from getting a full rinse. This can leave the fabric stiff with residue from minerals, dirt, and detergent. The same goes for drying! Be patient and run multiple loads to avoid overcrowding. If your home's water supply is "hard" and full of minerals, then the faucet or washing machine might be leaving chalky deposits in your towels. Consider buying a mineral filter to soften up your water supply, or washing your towels only with off-grid water.
