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
