The pressure from the tank is based on the height of the tank. A tank on a 25' tower will supply at least 12.5 pounds per square inch. (we don't know the height of the surface of the water.) The 3/4 inch pipe has an area of .44 sq in. Thus the 3/4 pipe will have a pressure of 5.5 psi.
1. You must keep the eggs at the appropriate temperature. While the appropriate temperatures vary from one species to the next, most eggs need temperatures between 80 and 90 degrees Fahrenheit.or lizards that deposit eggs out in the open, cover the eggs with a small deli cup to protect them. Place a small hole in the cup to provide a small amount of airflow, and place a slightly damp paper towel in the container to keep it from drying out.
Ideally, eggs should not be more than 7 days old when they are set (placed in incubator). Beyond that point, hatchability declines. If it is necessary to hold the eggs before you set them, turn them daily and keep them in a room where the temperature is around 50 o F (10 C) and the relative humidity is 70 to 80 percent. The vegetable section of your refrigerator could be used for holding the egg until it is time to place them in the incubator.
