Use Activated Carbon: Activated carbon is an effective and natural way to filter out impurities, including ammonia. A water softener works by exchanging hard minerals for sodium ions to soften the water. The Breakpoint Chlorination (units) are calculated by multiplying the above with the Pool Volume (PV) and the Standard Quantity (SD) recommended as per the formula below: BC = (TCL FCL) X 10 X (PV / 10,000) X (SD / 10), This quick reference chart, from In The Swim, is based on 10,000 gallons of water and is used as SD:if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[728,90],'thepoolanddeck_com-medrectangle-4','ezslot_0',165,'0','0'])};__ez_fad_position('div-gpt-ad-thepoolanddeck_com-medrectangle-4-0');PoolShockTypeIncreaseby 10ppmCalcium Hypochlorite1.3 lbsSodium Hypochlorite3.5 qtsLithium Hypchlorite2.5 lbsDichlor1.5 lbsSource: In The Swim. For breakpoint chlorination, enough chlorine must be added to the water to break down the existing chloramines, oxidize the contaminants to produce new chloramines and then break down the new chlorines as well. (A Helpful Guide! . To ensure chlorine break point was reached after shocking, total chlorine should equal free chlorine and both should raise in tandem when more chlorine is added. Sufficient chlorine is put into a pool to raise the free available chlorine level to 10 times the amount of combined chlorine in order to reach the breakpoint. Direct leaf absorption speeds the rate of accumulation of toxic ions. In the fourth stage, the added chlorine can start to build up the free chlorine level. EIQ~^.+awuuM^:m >9}sc}|:=9bc?dGEyy|jOOVc>NO>'i}yjp*)U2j]:V}X} >C. Several trace elements are essential nutrients in low concentrations. An easy why to factor the necessary amount of chlorine to shock to hit break point is to increase chlorine ppm ten times the total combined chlorine. 2. The Breakpoint Chlorination (units) are calculated by multiplying the above with the Pool Volume (PV) and the Standard Quantity (SD) recommended as per the formula below: BC = (TCL - FCL) X 10 X (PV / 10,000) X (SD / 10) Where: BC = Breakpoint Chlorination (units) TCL = Total Chlorine Level (ppm) FCL = Free Chlorine Level (ppm) A Breakpoint Chlorine Curve .

Free chlorine immediately goes to work killing the contaminants. The ultimate objective of the breakpoint chlorination is to reach stage 4, where all the contaminants in the water have been neutralized, the level of chloramines is at its lowest possible and free chlorine increases to the recommended level. However, it is also important to determine the levels of organic chloramines to avoid overestimating the disinfectant residual. So if you have a Combined Chlorine of 2 ppm, you should add 20 ppm worth of available chlorine. Theoretically, exceeding the "breakpoint" prevents increased levels of disinfectant byproducts (like chloramines). = 6.175 Lbs.) Qty. field. You are using an out of date browser. Yes. We recommend shocking with either Calcium Hypochlorite (un-stabalized granular only, not tablets) or with Liquid Chlorine (Sodium Hypochlorite).
