The hardness if formed by Bicarbonate ions. The only way to lower the hardness (usually measured in KH/GH) is to use reverse osmosis water, however this can be costly. It would be much cheaper and far more convenient to simply choose fish which are suited to your water conditions.
Basically, you can’t and you will also have problems with limescale from a visual point of view, pretty much the same as the inside of a kettle.
Choose your fish to suit the water. Mucking about with the hardness and consequently the PH is a skill with no margin for error if the fish are to live.
If you go to your local fish shop you more then likely can buy RO water.
RO water is the same as bottled water, where 99.9% of all the impurities have been removed. the only problem with RO water is that it has a very low PH (around 6) but all you need to do to raise it is put and air stone in it, or leave it to sit for a few days.
it should go back up to PH7.5 in about 2 days.
You may want to try water softener pillow which can be placed into a small Internal filter .these pillows can recharged by removing it from the filter and placing them in a container 4oz of cooking salt to 120ml of water for 2hrs the solution my be used for recharges then discard the solution. I have have had rasboreas in the past with out any problems put if you want to breed them you then you need to soften the water …I was told that hard water forms an hard shell around the eggs stopping the from hatching
