Water hardness or softness refer to a number of water parameters. Most commonly hardness refers to what known as General Hardness(GH), which is basically a measure of the calcium and magnesium salts present in water. There is also Carbonate hardness(KH), which is a measure of the carbonate concentration of the water. Combined, these two form Total Hardness, ie, GH + KH = TH

There are two ways to help control water hardness: use a packaged water softener or use a mechanical water softening unit. Packaged water softeners are chemicals that help control water hardness.
The best way is to control the harness and softness of the source water for the aquarium. If you need soft water, then use a water softener or reverse osmosis machine to lower the water hardness. If you need your water harder, then you can purchase remineralizing compounds that you can mix with water change water and then add to your tank. You can find remineralizers at www.bigalsonline.com. Look under Water Treatment > Ph Regulators & Buffers. I recommend Kent's R/O Right.

There are crystals available in many pet shops that can be placed in a filter to remove hardness. To increase hardness you can add sea shells. To neutralise the water you can get 'Neutralising blocks'. If you are really keen you can use a reverse osmosis filter to remove all the hardness (and other impurities) from the water and then add all the required chemicals to make the water exactly what a specific species requires.
