Use a specialty algae scrubber or a lint-free cloth to gently rub the inside of your tank. Apply consistent and light pressure while making small circles on the surface. It is okay if pieces of algae fall to the sand as they will be siphoned up shortly. Resist pushing too hard on your tank as it can cause damage or make the tank possibly tip over. Place your fingers into the sand at the bottom of your tank. Gently push the sand from the bottom to the top. Repeat throughout the tank floor until all sand has been upturned. You will see that debris and deposits have settled on the surface of the sand. It is sometimes helpful to go over the sand surface one time with the siphon prior to raking. Lower your siphon until it is about ½ inch above the sand’s surface. Move the siphon in a back-and-forth pattern, holding the depth level, as you pick up debris and dirt. Target any particularly large particles. You can expect for the siphon to pick up some sand particles with this method. You can then re-rinse those particles and re-introduce them to the tank or you can throw them out. It is often a good idea to add in new sand every few weeks anyway. Take your time picking up the clean decorations and putting them back into the tank. You can follow the same pattern as before or you can mix it up with a new design. Make sure each piece is anchored and move around the freshly cleaned sand as needed. Replace the water that you removed by adding in the treated water to your tank. You can pour directly from the bucket, although that may disturb your tank and fish. A better option might be to use a jug to add the new water in slowly. You can also deflect the water with a plate as it is added in which will lower the chance of damage even more. As soon as you’ve completed the water change you can plug all of your tank appliance back in. Watch to make sure that they are operating properly before leaving the tank alone.  You may want to leave your tank light off for a few hours following a water change. This can help your fish to relax following what may have been a stressful event. Check the temperature of the replacement water with a thermometer before adding it to your tank. Both water temps should be roughly the same or you risk shocking your fish.

Q: Before you make any decisions regarding the method you'll use to stretch your ears, consider how much you want to stretch them. If you're only moving up a size, the most pain-free option would be gently pulling your ears until they stretched out enough to accommodate new earrings. If you're looking to stretch your ears considerably, however, explore other options. Tapering is the most common method to stretch out your ears. If done correctly, this method is relatively painless.  Tapers are sets of rods that gradually increase in diameter. To stretch your ears, you would get a set of tapers, push the taper all the way through the hole, and replace it with a gauge the same size as the end of the taper.  By the time you complete the set, your ears should be stretched as large as you want.   Never wear tapers as jewelry. This will make your ears heal unevenly because of uneven weight distribution. Some people use spiral gauges as tapers, they can be work for long periods of time and allow for longer stretching periods If you want to stretch your ears slowly, consider taping. This allows you to gradually stretch your ears, which can reduce pain, but in smaller increments than you would use with tapers.  To tape, use non-adhesive tape. Wrap this tape around the parts of your earrings entering your ear. Increase by one or two layers at a time until you've stretched your ears to your desired diameter.  Wash your earrings after taping to prevent infection. You should not wear silicone plugs until your ears are fully stretched and healed. If used when stretching, silicone can tear the lining of the ears and potentially cause infection. Double flared jewelry as flares are sometimes large enough to cause pain and possible permanent damage to your ear.
A: Tug gently on your ears. Consider tapers. Try taping for gradual adjustments. Avoid silicone and double flared jewelry.
