Perhaps the best way to filter calcium from your water supply is to use a water softener. A water softener has been specifically designed to strip hard minerals, such as calcium and magnesium, from your water supply.
One of the most effective ways to get rid of calcium and lime deposits is to purchase and a water filter and softener combo system. The best water filter for removing calcium and lime in 2023 is the Springwell CSS1, which is a dual tank combination system of water filter and water softener.
USING BAKING SODA OR VINEGAR
Baking soda is alkaline, while vinegar is acidic. Baking soda and vinegar are both natural disinfectants that can be used to turn hard water to soft water. They eliminate the scaly coating that occurs in hard water as a result of mineral deposits.
Soften your kitchen water by boiling: Boiling will make the salts in water sink to the bottom of the boiler. You can then scoop out this water or pour the water in another pot leaving the deposits in the end. Install an ion-exchange filter to your kitchen faucet or use a water pitcher filter.
Hard water can be softened by adding sodium carbonate (washing soda) or by passing the water through an ion-exchange column.
BRITA filters do not filter out all calcium or magnesium. Instead, they work by reducing the carbonate hardness of the water, so that calcium carbonate is less likely to develop. So you can still enjoy healthy minerals.
Softened water still contains all the natural minerals that we need. It is only deprived of its calcium and magnesium contents, and some sodium is added during the softening process. That is why in most cases, softened water is perfectly safe to drink as it contains only up to 300mg/L of sodium.
Both reverse osmosis and a water softener can be strong options for removing calcium from your water supply, but a water softener is probably the most cost-effective and efficient way to do so.
Two of the most effective substances are lemon juice and ordinary vinegar. Lemon juice is usually the best (and will also leave a lovely smell behind). Stronger pickling vinegar and lime juice are both even more acidic and can be used for really stubborn deposits.
Muriatic acid is a strong hydrochloric-based acid, that is a great descaler. Because of the intensity of this acid, it has the ability to remove severe lime and calcium deposits found in pools and toilets.
With Vinegar: Wrap a bag or cloth covered in vinegar around your faucet. Keep it there for several hours and wipe down the surface when you're done. Vinegar and baking soda can also be combined to make a paste for scrubbing calcium deposits.
Disadvantages of home water softening
Can corrode your pipes. The corroded metal from the pipes can end up in your water. This can contribute to elevated lead and copper levels in drinking water. Potential health effects from additional sodium.
As a good rule of thumb, you should start by setting your water hardness level on your water softener to match the GPG of your water supply. For example, if your report shows you that your water hardness level is 10 GPG, then you need to set your water softener to 10 GPG as well.
Don't Add Too Much Salt
Adding too much salt to your water quality softener can cause salt “bridging,” or a buildup and solidification of regenerant. This buildup can prevent your system from regenerating properly.
Water described as “hard” contains high amounts of dissolved calcium and magnesium. Hard water is not a health risk but is a nuisance because of mineral buildup on plumbing fixtures' and poor soap and or detergent performance. Water is a good solvent and picks up impurities easily.
Bottled water is hard water as it contains lots of dissolved minerals. Hard water can cause problems in the home for example the build up of lime scale in kettles but it does have the benefit of tasting nice. There are two main types of bottled water, spring water and mineral water.
Vinegar. Because vinegar is acidic, it's one of the best hard water treatment options for clearing out scale buildup in your tub and sink. You can even use it in your appliances, like your coffee maker, dishwasher, and washing machine, to help them function better.
The most common way to treat hard water is with a Water Softener. This is a water filtration system that filters out the hard water minerals in your water. Was the water travels into the filter, it passes through a bed of resin that traps the calcium and magnesium, which are then replaced with sodium ions.
Naturally lower your aquarium hardness by soaking dechlorinated tap water in peat moss, Indian almond leaves or driftwood. A more precise method would be to dilute tap water with reverse osmosis (RO) or distilled water or to use remineralized RO water.
