Start by calculating the volume of water in your pool using our Pool Water Volume Calculator. Just enter the dimensions of your pool (in metres) and the calculator will work out the approximate volume of your pool (a metric converter is provided to aid you with this). Following this, you can use the chlorine dosing calculators to work out the

Chlorine tablets come in one-inch and three-inch sizes. For most pools, a three-inch tablet is recommended. They're more straightforward to apply and can sanitize 5,000 gallons per tablet. Smaller pools and hot spas require one-inch tablets. Compared to liquid chlorine, tablets are quite acidic at 2.5 pH.

The main issue with using dichlor is the fact that it contains such a high amount of cyanuric acid (pool stabilizer), and while the chlorine gets used up in a matter of days, the added stabilizer degrades at a much slower rate, which soon causes a buildup. Yes, cyanuric acid is useful for pools that are exposed to the sun. The number of gallons a 1-inch chlorine tablet treats depends on the tablet’s concentration. Commonly, a 1-inch chlorine tablet can treat around 1000-2000 gallons of water. How much salt do I put in a 200-gallon hot tub? Salt is not typically used as a sanitizer in hot tubs. To determine the total number of pounds of Calcium Hypochlorite needed to provide 1 lb of Chlorine, divide the dose required by the percent chlorine. 100 ÷ 0.65 = 153.8lbs (1.8.1) (1.8.1) 100 ÷ 0.65 = 153.8 l b s. Therefore, you will need to use 153.8 lbs of Calcium Hypochlorite to obtain a 100 lbs dose of chlorine. Chlorine is a greenish yellow gas at room temperature and atmospheric pressure. It is two and a half times heavier than air. It becomes a liquid at −34 °C (−29 °F). It has a choking smell, and inhalation causes suffocation, constriction of the chest, tightness in the throat, and—after severe exposure— edema (filling with fluid) of the . 212 306 71 344 305 379 335 212 114
