My refrigerator has a 500 watt compressor that runs about one fifth of the time. I am paying $0.13 per kilowatt hour.hen multiply that by 365 to get annual consumption. For example, I plugged my Kill A Watt meter into my Maytag 18.5 refrigerator and left it in for about 3 days. After 74 hours and 53 minutes the Kill A Watt meter registered 3.96 kwh. Hereâs how I determined the watts consumed by my refrigerator per year:
Thus, an effective way to clear a tank from ich is to remove all of the fish for a certain amount of time. At 80 degrees Fahrenheit, ich tomites will die at 2 days in the absence of fish, and just to be absolutely sure, some recommend keeping the tank empty of fish and at 80 degrees for 4 days (96 hours).
Ideally the readings should be no more than 77Â°F (25Â°C) when the lights are on and no less than 64Â°F (18Â°C) when they are off. The optimum temperature for active metabolism in most plants' root zones is around 64Â°F (18Â°C). Ensure that your water or nutrient solution is at this temperature too. If using tap water, be sure to add just enough from the warm tap so that the water feels tepid-not warm, not cold, just silky to the touch.
