The clarity and transparency of pool water entirely depends of two factors namely filter effectiveness and balance of the chemicals in the pool.
When there is a threat to any of the above factors, the result is "cloudy pool".
Let us see the ways to fix a cloudy pool.
About 3/4 of the water clarity is achieved by using good filters.
The remaining depends on the chemical used for treating the water.
The filter media plays a vital role in maintaining the clarity of water.
Replace the filter media if it has been used for a long period.
Manual cleaning should be done in the case of D.
E.
filters.
Change the cartridges in case if it is a cartridge filter.
Some may use sand filter where the sand can be replaced or it may require backwashing.
I do go into more detail on how to do this in my newsletter.
While considering the balance of chemicals three factors such as alkalinity, pH value and calcium hardness play a major role.
Calcium hardness is measured using a water testing kit and it should be maintained about 200 to 400 parts per million (ppm).
The alkalinity should either be around 150 to 180 ppm.
For better results, try to maintain the alkalinity as low as possible.
Add sodium bi sulphate to decrease the pH value of water and to raise it add soda ash so that the pH value between 7.
2 to 7.
6 is maintained.
Make sure all the above statistics is maintained properly for balancing the water to eradicate cloudy pool.
