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.
Calcium Hardness Increaser is purchased at your local pool suppy store.
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.

If the calcium is a result of pool chemicals, draining some or all of the pool water will lower the calcium hardness level. If the cause is the fill water, commercial hardness reducers or chelating agents will bond with the calcium to keep it trapped in solution.
You'll have to replace some or all of your water. There is no method to remove calcium hardness.
Maybe, if the swimming pool must be cleaned frequently, would prevent the buildup of calcium.
Try keeping the water "balanced" that will improve your odds.
You have to drain the water down and add fresh water in the pool. Try not to use so much calcium hypocrite (Shock) in the pool because this could be why your level is high.

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).
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.
Calcium comes in 3 major forms: calcium citrate, calcium carbonate, and calcium phosphate. Critical, or calcium citrate, is the best choice for your needs.
Hard water means it is 'basic' and so has a high pH value (>7, likely 8 or more) so you need to add a 'acidic' substance such as vinegar or phosphoric acid in weak solution, but the best way is to buy a water softening electric coil that wraps around the cold water source in your basement (or where ever) and plugs into the wall. This will cause a ionic reaction that prevents limescale from forming in kettles, showers and pipes anywhere in the house. It'll also help keep your water heater working for much longer.
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.
Citrus fruits are the best source of calcium.

Salt water iscleaned the same way as any water. it is run through filters. this cleans the water as in salt water swimming pool but does not remove the salt. to remove sat you need a desalinater.
The only way to lower it is by removing some or all of the water.
A really stale piece of bread. It's so hard I used it in my science project as a rock. Sure enough, it actually survived!
