High Calcium Hardness can only be lowered by partially draining the water out of the pool and refilling from a water source with a lower Calcium Hardness reading. There is no chemical available to lower Calcium.
The cloudy water could be the result of a malfunctioning filter or too little run time of the filter system if it is controlled by some type of timer as well as a chemical problem.
Have your water tested at a reputable pool store or service company and request a copy of the results for your records. They should be able to instruct you on any chemicals you may need to add.
To quickly test your filter for proper operation, you can perform this easy test-
1. Verify the filter pump is running properly
2. Remove the lid of the pool skimmer and remove the basket.
3. Take a handfull of dirt and drop it into the skimmer while filter system is running, for safety- do not stick your hands under the water in the skimmer while the basket is removed and the filter pump is running. Just drop the dirt into the water.
4. Quickly move to the closest return in the pool. This is where the filtered/heated water comes back to the pool.
5. Closely watch the return and see if any of the dirt you put into the skimmer is getting by the filter and coming back to the pool.
You should not see any dirt coming back to the pool. If you do see dirt, it is reasonable to assume the filter is damaged internally and is not removing particles from the water as it should. The filter will need to be taken apart and inspected by a professional pool service mechanic and repaired or the entire filter replaced.
The three types of pool filters are: Sand / Cartridge / D.E. (Diatomaceous Earth)
Sand being the least effective of the three.
Chemical pool water Clarifiers should be used as a last resort and should never be used if you have a D.E. filter system.
