The best way to lower calcium hardness in the pool water is to drain the water and refill with water of lower calcium hardness. Have the calcium hardness tested for both the pool water and fill water. Ideal range is 175-300ppm. There are 'calcium reducer' products available through pool stores, but not sure how effective or economical they are.
You can, if the water presently in the pool is 'hard' - but be very careful to keep an eye on the Calcium Hardness of the pool water. If you filled a pool with water from the softener, the water would be hungry for calcium and drag it out of the pool walls, making them feel and look like sandpaper. Calcium hardness should be kept within 200-275ppm. best to use regular water for topup and keep the pool water properly balanced (see your local pool store).
The hardness of bottled water can vary widely depending on the source. Typically, bottled water has a low to moderate level of hardness, with most falling within the range of 20-100 mg/L of calcium carbonate equivalents. It's best to check the specific water quality report provided by the bottling company for accurate hardness levels.
The average water hardness in well water can vary depending on the location. Generally, well water tends to have higher levels of hardness compared to municipal water sources. In the United States, the average hardness ranges from 60-180 mg/L of calcium carbonate. Testing your well water is the best way to determine its specific hardness level.
There are some things that do this, but I would first check your calcium hardness level. Water is hungry for calcium and will try to get it anywhere it can. You need to feed its appetite. While I agree with the notion that some pools need calcium, I prefer to keep my pools between 150-250ppm. This level comes from an index used specifically for pools. Anything lower or higher than this range comes from an index used for public water systems that was "grandfathered" in and used for pools because no other index was available. Many pool guys will say keep your calcium at the higher end, about 400ppm. Keep your at 150-250ppm, get a good Taylor Reagent DPD test kit, learn the "swirl" technique, and you'll be fine.

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.
Water is the best solvent for calcium carbonate, as it can dissolve it under certain conditions due to its polar nature and ability to interact with the ions of calcium carbonate. Other solvents like acids or organic solvents can be used to dissolve calcium carbonate as well, but water is the most commonly used due to its effectiveness and availability.
The relative hardness of a mineral can be best tested by conducting a scratch test against common minerals with known hardness values, such as the Mohs Scale of Hardness. By observing which mineral scratches another, you can determine the relative hardness of the unknown mineral.
Citrus fruits are the best source of calcium.

When oxygen gas is added to lime water (a solution of calcium hydroxide), it reacts with the calcium hydroxide to form calcium carbonate, which is white and insoluble in water. This reaction causes the lime water to turn milky.
Low calcium hardness is increased by adding calcium chloride. The amount needed may be worked out using the calcium chloride calculator.on the link belowdivide the correct amount of calcium chloride into 3. Add the first part and circulate the water for at least 4 hours. Test the water again and repeat the process until the desired level is reached.
Yes, nuts contain calcium, with almonds and Brazil nuts being among the best sources of calcium.
