It will make the water cloudy. to remove calcium carbonate simply lower pH in the pool to 7.0 or lower and calcium carbonate will redissolve back into suspension and water will clear up.
You can get this characteristic by adding sodium Carbonate too quickly.

What else is in common with calcium carbonate and hydrochloric acid?
most pool/spa chemicals calcium carbonate :is basically tums or any other ant-acid and as for the hydrachloric acid : chlorinated water (in concentrate)
What if you used water softener in your salt water pool?
Filling a plaster pool with water from a salt type softener will severely damage the plaster. Salt water softeners exchange salt for calcium and leave the water in a calcium deficiency. Seeking its dynamic balance the water will leech calcium from the plaster to satisfy its need for calcium making the plaster etched and rough. Adding salt to regular tap water is not the same as filling with soft water as the calcium is still present in the tap water. 180 ppm of calcium is considered the minimum and low calcium can be raised by adding calcium chloride.
What does it mean when calcium hardness is low in a pool?
Low Calcium Hardness in pool water means that there is low calcium in the water and is considered "soft" and soft water tends to be corrosive. It will etch away and your plaster and any metal object the pool water touches.
How do you raise pool calcium?
To raise calcium in your pool use calcium chloride. You premix it in a container to let it dissolve and add 6lb for 10pmm in a 50,000g pool.
What to do with high pH in pool?
If memory serves me correctly, high PH is lowered with Calcium Carbonate. You probably want to consult someone who is licensed in pool care, however.
Should you tie the pool water leveler to the water softener?
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).
What does buffer and added hardness do for a saltwater pool?
Buffer and added hardness do the same thing in a salt water pool as in a fresh water pool. The buffer (sodium bicarbonate aka bicarbonate of soda) stabilizes the pH of your pool so that addition of acid or base doesn't change the pH very much. The hardness, mostly Calcium, helps achieve water balance to make the pool neither deposit (precipitate) excess Calcium Carbonate to your pool surfaces nor corrode (remove) Calcium from your plaster pool surface. The combination of pH, Total Alkalinity (adjusted for Cyanuric Acid), Calcium Hardness, temperature and Total Dissolved Solids determines whether your water is balanced. Just keep these values near their recommended amounts for your pool and you should be fine. If you're a techie and want the full formulas, do a Google search for "Langelier Saturation Index".
Is soft water from a home softener system ok to feed the pool auto leveler?
I would only connect the soft water to the auto-fill if you are having a problem with the pool water being 'too hard'. If you do not have hard water in the pool, there is no advantage in using soft-water for topup. You can use the soft water BUT you MUST maintain the correct level of calcium hardness in the pool water (200-275ppm is good). If the calcium hardness falls too low other problems can occur, including damage to plaster walls.
What is the best way to lower the calcium hardness in the water in the pool and the water used to fill it?
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.
How do you lower hardness in pool?
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.
What does adding calcium chloride flakes do for your pool water?
Calcium chloride increases the hardness of water. Proper hardness is critical to balancing the water in a pool. Proper hardness is especially important in a plaster pool to prevent leaching of the plaster finish, which results in a rough surface. Calcium chloride can be purchased at home improvement stores at significant savings over pool supply outlets.
How do you get calcium out of the water in an in-ground swimming pool?
Turn the pool upside-down and knock on the bottom.
