Is your pool water cloudy or murky? Vistancia Pool Care can test it to see if your pool has chlorine block.
If your pool has been looking cloudy or non transparent lately it could be due to high levels of CYA and TDS. These high levels often cause a chlorine block in the water and make it hard for the chlorine to clean the pool. Vistancia Pool Care can test the water for hight levels. If your pool water tests with high levels of CYA and TDS then it is time to drain the water.
