Q: The standard measurement is liters. You should be able to figure out how big your tank is when you initially purchase it. But if you don't know (or don't remember) the size, you can figure it out on your own mathematically. To find out how many liters your tank is measure the length, width, and height of the tank in centimeters and multiply them together, then divide by 1000. This number is only approximate as the actual value will be rather less due to glass thickness, substrate, decorations, etc. Have the water at the right level to accurately calculate how many fish will fit. If your water levels get too low, your tank won't be able to sustain as many fish. Typically, you should keep the water level about one inch above the lip of the tank's water filter. However, this is not always true. A ten inch fish cannot live in a ten gallon tank. This guideline works best for small community fish like tetras, rainbowfish, platies, etc. Do research on the fish you want to determine what size tank they need. Since the surface of the water is where gaseous exchanges happen that help sustain your fish, it is important to consider this factor when stocking your tank. A larger surface area means more oxygen exchange for the fish in the tank. A taller tank with the same surface area as a shorter tank isn't able to house more fish even though it technically holds more water. Typically this is a better rule of thumb to use when deciding how many fish to keep in your tank because it accounts for the oxygen needs of the fish, rather than just the available space in the aquarium.
A: Measure your tank. Maintain proper water levels. A common rule is the, one inch of fish per gallon of water rule. Use the surface area rule.

Article: You may need to install the valve assembly (all the parts inside the tank) if it is not pre-installed. There should be appropriate instructions on the packaging when you purchase the assembly, but you can also ask your local hardware store employee for advice. If they were not already installed, you will need to secure these to the toilet with the appropriate bolts. Reconnect the water supply line, using either the new line or the old one if it was in good shape. Try flushing a few times once the water is on to make sure there are no leaks. Choose an appropriate caulk and thoroughly caulk around the base of the toilet. Once this is dry then you're done. You may prefer to omit this last step. If you have a leaking wax seal on your toilet, or if a wax ring seal leak develops later, you will trap water under the base of the toilet. If the sub-floor is wood it will eventually rot it out leading to all sorts of problems when repairs are necessary.

Install the toilet valve assembly. Install the toilet seat lid and ring. Reconnect the supply line. Turn the water back on. Caulk the base of the toilet.

Problem: Article: For young dogs, the first sign is usually that the dog has wobbly rear legs, has difficulty climbing stairs, or is unable to jump into a car. It may also not be able to run and exercise easily, as you would expect a young dog to do. Dogs that are 6 - 12 months old can present with sudden back end lameness, or their symptoms may just gradually worsen. If both hips are affected, the dog may stand with a clearly dropped rear end. It may also move in a bunny-hop motion, swinging both back legs forward at the same time instead of moving them independently. Pain may cause the Rottweiler to be less tolerant than it was previously. Rottweilers need a lot of exercise. If they are unable to do this they can grow bored and may display a tendency toward aggression. Some dogs may react aggressively because of pain, if you go to stroke or touch the hip area. In older dogs, the key symptom of dysplasia is back end lameness. Thus, a dog may walk with a limp and when you look at it from behind you may notice there is less muscle mass on the most severely affected leg. Dogs with hip dysplasia have a tendency to rest the sore leg when standing. They may also exhibit hesitation before moving from a standing position.
Summary: Look for an unstable rear end. Watch out for a dropped back or awkward movement. Be on the look out for a change in character. Pay attention to limping and muscle wasting.

INPUT ARTICLE: Article: A sewing or embroidery hoop is a simple hoop made from metal and/or plastic that holds a piece of fabric in place when you're sewing. Any size hoop will work, but a hoop of about six inches across will be the same size as most pop filters. Embroidery hoops usually have a fairly simple latch on one side. Undo this latch and slip the fabric over the inner hoop so that it stretches beyond its edges on all sides. Seat the inner hoop back inside the outer hoop and close the latch, keeping the fabric tight. See our embroidery hoop article for more help. It may seem counter-intuitive, but stiffer fabrics tend to make better pop filters. If you have the tight metal or plastic netting that's usually stretched across the open spaces of screen doors, this works especially well. Simply stretch it across the embroidery hoop as you would with the embroidery fabric. Screen door mesh can be found at most large hardware stores. It's cheap, but you may be forced to buy a roll of the material, rather than the small amount that you actually need. Now, all you need to do is move your new pop filter into position. As in the section above, one easy way to do this is to tape, glue, or clamp the outside the hoop to a free mic stand. You can also attach the hoop to a stick or a straightened-out coat hanger and then attach this behind the microphone. Sing or talk through the filter and into the mic as normal. With this method, the filter is only one layer thick, but this is OK. It should work just as well.

SUMMARY: Obtain a embroidery hoop filter. Stretch nylon embroidery material across a sewing hoop. Alternatively, use screen door material. Position the hoop in front of the mic.

Article: If your polyester garment is holding a static charge, turn the garment inside out. Grab a can of aerosol hairspray and hold it about eight inches away from the polyester garment. Spray the hairspray onto the garment to alleviate the static cling. This helps reintroduce moisture in the fabric, which can help break up static charge. Dry skin carries a positive charge and polyester carries a negative charge. As your skin rubs against the polyester garment, it creates static electricity. This is common in the winter when skin tends to be drier. Alleviate the charge by moisturizing before getting dressed. Dryer sheets are great for eliminating static in the tumble dryer, but they can also be used to remove static after the clothes have already dried. Grab a dryer sheet and glide it over the polyester garment to remove some of the static cling.
Question: What is a summary of what this article is about?
Spray aerosol hairspray onto your garment. Moisturize with lotion before wearing a polyester garment. Rub a dryer sheet over your clothes.
