Article: Keep your thermostat at a consistent and comfortable temperature. A conventional heating system usually requires you to turn the thermostat down while you sleep or while you're away from your home. By increasing the temperature drastically, you force your heat pump to work harder. It could also make a secondary heating system run and burn more energy. The heat pump will not heat the area faster if you turn up the thermostat. Your heat pump will not have enough power to keep your home at a comfortable temperature. The setting will either say "auxiliary" or "emergency" heat. Your energy efficiency will decrease the more you run an auxiliary unit.
Question: What is a summary of what this article is about?
Set your heat pump to "heat" at 68F (20C) for the highest efficiency. Avoid increasing the thermostat more than 2 degrees at a time. Turn on a backup heat unit if outside temperatures are below 35F (2C).
Article: Angelfish may not do well with other fish. They tend to be territorial, and may attack and even eat smaller fish. If you introduce other fish, stick to other angelfish or fish of a similar size. If an angelfish becomes diseased, you will need to talk to a vet or a pet store worker about treating the illness. This is especially important if you have other fish in your tank. One sick fish could infect the tank. Excessive slime and clamped fins can be a sign of a very serious disease called angelfish virus. If you suspect your fish has the virus, it may need to be put to sleep as there is no cure. White chalky feces, a lack of appetite, and weight loss can also indicate disease. There is also a common disease called ich that causes white spotting due to parasites. It can be treated easily with medication, so keep ich medication on hand when you have angelfish. If an angelfish is showing signs of disease, remove it immediately and place it in a quarantine tank. Seek the care of a veterinarian to discuss treatment options or ask at a local pet store. Do not put the fish back into the tank until the signs of disease have passed, as you do not want disease to spread.
Question: What is a summary of what this article is about?
Use caution when placing angelfish with other fish. Watch for signs of disease. Quarantine sick angelfish.
