Ideal Levels in Pools
The calcium pool levels should be between 200 and 400 PPM. This is not a small range, so most pools will always stay between this range. If you have to add chemicals for any reason, you should always check the calcium level to make sure that the water is ideal. You do want the calcium level to be too high or you will have to take care of any calcium deposits that can occur. The same is true for low levels. You must try to maintain a level between 200 and 400 to keep the pool free of any problems.
Swimming Pool Calcium Deposits
If your calcium pool levels are low, you will see deposits that will need to be cleaned and removed from any fixtures. Prolonged exposure to calcium deposits will cause corrosion that can damage the fixtures. You will not want to drain a pool to clean the calcium deposits so you will need to use a cleaner that is especially made for cleaning fixtures while the water is still in the pool. Swimming pool calcium comes from the unbalance chemicals in the water, and this must be corrected first or you will just be defeating the purpose.
Fixing the Calcium Pool Level
If the swimming pool calcium level is high, you will need to either reduce the water level or increase the water level by using a calcium hardness reducer. If the levels are low, you need to ad calcium chloride to the water. This should be done according to the directions on the canister. You do not want to use too much of the increaser and create high levels. Make sure to read the directions and add the increaser according to the directions. Then test the water again after a day.
Swimming pool calcium is not healthy for swimming. It can cause burning of the nose and eyes. It can also affect the skin if the person is sensitive to calcium hardness. Test the pool levels weekly and use the correct way to reduce or increase the levels in the water. One way to take some of the water out of the pool is to backwash the pool for as long as it takes to bring the water level to where it should be.
