A conventional electric water heater will come with a black wire and a red wire which are connected to the wires of the same color as described above. The ground wire is attached to the green ground screw which is in the same wiring junction box compartment which is built into the top of the water heater.
Using Sulfur to Lower Soil pH. You can make larger adjustments to your garden soil pH by using some form of sulfur. Sulfur lowers soil pH as it is broken down by bacteria in the soil and converted to sulfuric acid. Sulfur is most commonly added in the forms of aluminum sulfate, iron sulfate and elemental sulfate.
Methods for Soil pH Use the spoon to weigh out about 10g (to the nearest half gram), of your soil into the container. Add 50ml of distilled water to the soil. Any rough measurement ensuring a 1:5 diluted will suffice. Shake the container for about 2-3 minutes then allow the soil to settle for 2 minutes.
