Article: Pregnant platies are easy to spot, so if you keep a close eye on your fish, they shouldn't be a surprise. A pregnant platy will develop a noticeably swollen belly. They can also have an almost rectangular stomach as well when they are close to giving birth. It's also common for a pregnant female to develop a dark spot near her back fin. This is caused by the eyes of the unborn fry pressing against her scales. For a few adult platies, a 10 gallon tank is usually sufficient. However, if you plan for your platies to breed and you want to keep the fry, a much larger tank will be necessary. A minimum tank size of 29 gallons is recommended if you plan on letting your fish reproduce not letting them eat their fry. Because platies do eat their young, you will end up with the greatest number of surviving fry if you purchase a separate tank for them to live in while they grow. A separate aquarium for your fry can be purchased at most pet stores. This tank should be at least 5 gallons (or more, depending on how many babies the mother produces). To survive, whether in a community tank or in a separate tank with only their mother, your fry will need hiding places to escape to. This purpose can be served by either a lot of plants or a breeding trap. Plastic plants can be used, but live plants can often be a source of extra nutrition for your fish, who may take small bites of them to supplement their diets. There are many types of live plants that platies enjoy, which should be available at your local pet store. Good choices include bunch plants, such as anacharis and cabomba, floating plants like hornwort and water sprite, and mosses such as java moss. Many (but probably not all) of your platy fry will survive in a community tank if it contains enough plants for them to hide in. A breeding trap is a plastic box with small holes that goes inside a fish tank. The mother is placed inside the breeding trap, and when the fry are born, they can escape through the small holes to avoid being eaten. The mother will not be able to follow them. If you've opted for a separate tank to keep the fry isolated from the adult fish, separate the mother as soon as you can after you've noticed she's pregnant. You generally have between 24 and 30 days to make accommodations for your new fry once the mother shows signs of pregnancy. Once the mother gives birth, you can expect to have 20-40 new fry on average. Sometimes, this number can climb as high as 80.

Problem: Article: Make sure that both the TV and DVR are off before connecting them. You can keep both devices plugged into a power source as long as they remain off while you connect them. Plug the DVI end of a standard HDMI-to-DVI cable into the DVI In port on the back or side of your TV. If you cannot find an HDMI-to-DVI cable, you can use a standard HDMI cable and an HDMI-to-DVI adapter. Simply plug one side of the HDMI cable into the HDMI port on the adapter and plug the DVI connector on the adapter into the DVI In port on your TV. Plug the HDMI end of the same HDMI-to-DVI cable into the HDMI Out port on the back of your DVR box. If using an HDMI cable with an adapter, simply plug the free end of the cable into the HDMI Out port on the DVR. Connect the plugs at one end of an L/R audio cable into the matching Audio In ports on the back of your TV. The red plug should be plugged into the red Audio In Right port and the white plug should be connected to the white Audio In Left port. Connect the plugs at the other end of the same L/R audio cable to the matching Audio Out ports on the back of your DVR. Connect the red plug to the Audio Out Right port and the white plug to the Audio Out Left port. Now that everything is connected, turn the TV and and DVR on. Switch the TV to the appropriate input source to watch content from your DVR. You'll need to press the "Source" or "Input" button on your TV or remote control to change the source. The cable is connected to the DVI port on your TV, so you need to scroll through the options until you reach "DVI."
Summary: Turn everything off. Connect the DVI end of the cable to the TV. Connect the HDMI end of the cable to the DVR. Hook up the audio wires to the TV. Hook up the same audio wires to the DVR. Turn everything back on.

A central air conditioner is the most expensive and difficult-to-install option, but it can cool your entire home. A central air unit will cost you between $3,000 and $7,000. On top of this, you'll also have to spend money on a pre-installation evaluation of your home, any necessary modification or installation of ductwork, and the actual installation of the unit. During this evaluation, a qualified HVAC professional will check your home's ductwork to make sure it can handle the airflow of a modern air conditioner. They will also look for places where air leaks from your home, and determine the cooling capacity that is needed to properly cool your home. Call or visit a local trade organization for a list of qualified evaluators. Ask friends and neighbors for contractor referrals. You can also ask for a list of contractors from a local trade organization. Ask potential contractors for a list of customer references who can testify to the quality of their work. Ask contractors for price estimates for the installation. Be sure to receive a written, itemized list of the price estimate before the contractor starts the installation. Try to schedule the installation of your central air system during the spring or fall. Since these periods are the off-seasons for HVAC contractors, you may be able to find a lower price.
