The answer to this question is no, but there are a few factors that specify how long it will take before your pool is ready for swimming. The more important factors are knowing what your pool looked like when you closed it, knowing how long your pool’s water sat stagnant, and knowing how hot it got before you decided to open your pool. Daily testing and addition of chemicals is the key to getting a grasp on your water’s chemistry. Keeping an eye on the water’s chemical balance is the easiest and quickest way to getting your water Crystal Clear.
Opening your pool to black water and algae can be very hard to cope with mentally, but knowing how your pools chemistry works and how you can change it makes a huge difference when treating the water. When testing and adjusting your levels daily, keep in mind that Alkalinity should be the first thing that you test and adjust. The recommended level that you keep Alkalinity is 100 ppm, while the level you keep pH is 7.4. Chlorine should be kept between 3-5 ppm while opening your pool. After your levels have stabilized, you can reduce Chlorine to 2-3 ppm. Calcium Hardness, Phosphates, Total Dissolved Solids (TDS), Cyanuric Acid (CYA), and metals should also be tested daily until the water is clear. How long it takes to get your pool water swim ready is up to you.
* We do not recommend swimming in your pool the day it is opened. Stagnant water can be an incubator for different kinds of bacteria and parasites. This bacteria must be eliminated prior to anyone swimming in the pool. Bacteria, Parasites, Mold, and Mildew can trigger Asthma symptoms and/or allergic reactions in sensitive people, especially children. *
