How can I remove Lime Scale buildup in my water heater?

I live in a hardwater area 52 was the last reading and the lime scale buildup in my Gas water heater is unbearable! I also spend loads on cleaning products for other electrical appliances that work with water

Answers:
You need to flush out the water heater with a garden hose.
It is probably filled with little rocks.
The inlet is probably at the bottom of the tank.

Other answers:
Replace your water heater's anode rod. You'll need to turn off and empty it first. The web reference below has some additional info. And you'll often need a very big wrench to gain the leverage needed to free the old one.

Caution: the new rod will be about 4 feet long. Depending on the location of your tank, you may need to completely disconnect the tank in order to tip it on its side to change the rod. If you have to do this, depending on the age and condition of your tank, consider replacing the whole tank. When draining, inspect to see the amount of sediment particles that come out.
