Problem: Article: A filter is a vital piece of equipment to help keep your goldfish alive. The filter you'll need depends on the size of your tank, as filters operate according to a flow rate which will correspond with the amount of water your tank holds. Ensure you get a filter with the correct flow rate, and choose between an external or internal filter. If you can't match your tank's capacity to a the exact flow rated filter, go overboard. For instance, if you have a 20 gallon (75.7L) tank, shoot for a filter rated for 40 gallons (151.4L). External filters sit on an outside wall of the tank or within the tank's lid. Internal filters are submerged within the tank. Either type of filter can work for a goldfish tank. Lean towards opting for an external filter, as they have a greater capacity to store filtration materials, can clean water more thoroughly, and will require less maintenance. Your goldfish requires properly conditioned water to neutralize commonly occurring chlorine and chloramine. Feel free to use tap water, for instance, but add conditioner from a pet supplies store to make it safe for your goldfish to live in. Make sure the water has the right pH level too. For goldfish, ideal pH levels are a slightly alkaline 7.2-7.6 pH. Use a pH test kit to test your goldfish's water regularly, and adjust the pH if necessary with additives available at the pet store. Do not place the tank near a window or any heating or cooling source. Do not allow sunlight to hit the tank directly. Also be sure the tank is set on something flat and extremely sturdy. Though you will likely need to set your fish tank near an outlet, don't allow electrical cords dangle over your fish tank. An electrical shock could absolutely fry your goldfish, and be dangerous for you as well. Similarly, be sure that no cord is pulling against the side of the tank or the base that the tank is resting upon. Place the tank in a location it will not be jostled. You probably don't need a heater to maintain a temperature in this range, as it almost identical to the range commonly maintained in human dwellings. If you live in a particularly hot or cold climate, ensure that seasonal or daily changes in temperature do not put your goldfish at risk.
Summary: Use a filtration system. Add safe, clean, and balanced water. Place the goldfish's tank somewhere safe and sensible. Make sure the water temperature stays between 60F (16C) and 72F (22C).

INPUT ARTICLE: Article: If you are using regular latex paint to paint your upholstery, you will need to amend it. This means adding textile medium to the paint so that it sticks to the fabric. Mix together one part paint and two parts textile medium in a jar. This will thin out the latex paint and allow it to bond with the fabric. If you are applying paint to vinyl upholstery, you may need to apply an undercoat that helps the paint stick to the vinyl. This is only necessary for certain paints, so look at the directions of the paint you bought to make sure. The undercoat may be applied with a brush or from a spray can. This varies depending on the specific product you are using. Spray or paint on the first coat. Depending on the specific directions supplied on the product you are using, your first coat will either be very thin or thick enough to cover up the previous color of the upholstery. If you are painting vinyl, you want to be focused on a smooth, streak-less coat that does not drip. This is usually done by applying thin coats. If you are painting fabric, your first coat is likely to soak in a lot. You may not have complete coverage but just make sure that the entire surface has paint applied to it. It is important to let your paint coats dry completely between coats. This assures that the paint solidifies and sticks to the surface you are painting correctly. It also assures that subsequent coats dry quicker. Follow the directions on the paint container for dry times between coats. Each paint may take a different amount of time to dry. Put on more layers of paint until the surface is covered to your satisfaction. This may be only one more coat, or it could be numerous additional coats. Be patient and do as many coats as it takes to get the finish you want. Skipping additional coats can lead to a less polished finish or a shorter lifespan for the paint.

SUMMARY: Prepare the paint, if necessary. Apply an undercoat, if necessary. Apply the first coat. Allow the paint to dry between coats. Apply additional coats.

In one sentence, describe what the following article is about: Get in the habit of washing down the tub with a mild soapy cleanser and water every week. This will prevent dirt and grime from building up which would take longer to remove. Regular washing will also keep stains from forming in the acrylic tub and tile near the tub. Don't clean your acrylic tub with materials that can scratch the surface. Never use abrasive scrubbing pads or sponges. You should also avoid using steel wool which will also damage the surface. Instead, use soft cloths and sponges. For example, you could use a microfiber or terry cloth towel. You may need to use a drain cleaner or tub clog remover every once in a while. If you do pour this down your tub's drain, you'll need to rinse it away completely, so there's no cleaner or remover left standing in the drain area. If you leave cleanser or clog remover in the drain area, it could damage the acrylic surface. To avoid discoloring the tub, most acrylic tub manufacturers recommend that you never smoke in or around it. This is because tobacco smoke can permanently damage the tub.
Summary: Clean the tub out weekly. Avoid using rough sponges and cloths. Rinse the drains thoroughly. Avoid smoking around the tub.

In one sentence, describe what the following article is about: Slugs and snails can chew up your most prized plants, but they are not fond of coffee grounds. Sprinkle a handful of grounds around the bases of plants you want to protect. If you're worried about increasing the acidity of the soil, make a solid ring of grounds farther away from the base. It's thought that this works because the caffeine in the coffee grounds hurts these pests. Coffee grounds aren't just good for tiny pests. They can also be used to keep feline friends from playing in your delicate plants. In this case, use the grounds just as you'd use them to repel snails sprinkle them around the plants you want to protect. The acidifying effect on the soil may be unavoidable here due to how much you'll need to use. If you participate in vermiculture (raising worms), you have a great opportunity to use up your coffee grounds. Worms love to eat coffee grounds, so feel free to add plenty to your worm bin or a worm-containing compost pile. Note, however, that coffee grounds should be part of a balanced diet: fruit and vegetable scraps, newspaper, leaves, and so on should accompany any coffee grounds you add. There is some evidence that coffee grounds can be used to prevent certain types of fungus from attacking your plants. A light sprinkling of coffee grounds may be able to prevent Fusarium, Pythium, and Sclerotinia species of fungi from taking root. Tomatoes, eggplants, and peppers are especially vulnerable to fungal infections, so coffee grounds make an especially good choice for these plants.
Summary:
Use grounds to deter pests. Use grounds to keep cats out of your garden. Use coffee grounds as worm food. Use grounds to discourage fungal infection.
