<b>Pool and Swim Spa Salt Water Chlorine Generator</b><br /> It can be a challenge to to keep the water in your pool crystal clear and odor free. If you forget to add chlorine or the chlorine feeder runs out and you don't refill it that could lead to water quality problems. Even if the water looks good you should measure the chemical balance before use. Pool chlorine generators can greatly reduce problems and reduce maintenance as they continuously make chlorine every day so you don't have to remember to add it.<br /><br /> The MegaChlor makes chlorine on a 3 hour cycle. Every 3 hours it starts making chlorine, and based on the power level it will turn off at some point in that 3 hours and remain in standby mode, then at the next 3 hours it will start again. At power level 5 it will be on for 45 minutes out of every 3 hours. If you use the pool and let the MegaChlor DO know by pressing the boost mode button, it will be put into boost mode and be on for 3 times the normal on time. Boost mode helps to add the chlorine back after the pool is used.<br /><br /> Pools and Spas To 20,000 Gallons<br /> Chlorine production 100 grams per day<br /> 110/220 VAC Outlet That is GFCI Protected<br /> 15' Power supply cord, 10’ Cell supply cord<br /> Low 12Vdc power output<br /> 10 Power levels - No External Timer Required.<br /> Clear cell compartment allows for easy inspection of the salt-cell plates.<br /> Constant current design, salt level doesn’t matter (2000 to 4000 ppm recommended)<br /> About 3 pounds of salt per 100 gallons of pool water<br /> Simple Plug and play installation, no pool modification required.<br /> The cell simply hangs over the side of the pool into the water and the pool doesn’t even have to be on when the MegaChlor DO is making chlorine.
