I have a six year old pool frog hybrid system that I inheritted with our pool. Until we bought the place this summer, the system was run 24/7 during the swim season and maintaining the ultra low chlorine level they recommend. I put a timer on the pump, and raised the output up to run the chlorine the TFP way. It maintained the chlorine level while running the pump about 8 hours per day. Over the last couple months the output has dropped off. I tested the salt, added more to get it in the proper range, and even tried cleaning the cell. It was clean with no scaling prior to me cleaning it. One of the plates is corroded, and I figured it was probably close to the end of its life. Now the output won't go above the lowest level. I've been running it about 13 hours a day, and it has struggled to maintain the chlorine at the lower end of the recommended range. I've added bleach twice just to get it back up around 6-7 ppm, and it will slowly drift back down to about 3. I decided today to just switch over to bleach to get through the next month until I can close it, and stop wasting money on electricity running it so much each day. I'm weighing my options on salt cells/systems for next year. So far I'm down to either replace the cell with the next larger size for $448, or go to a pentair IC60 for $1046. Does anybody know of a definitive way to test the controller to make sure it is actually outputting the correct current? I'd hate to buy a replacement cell just to find out the controller is shot too. This system runs at 12vdc and varies the current based on the output setting. I've seen where others run up around 24vdc, or vary the voltage between 12-24vdc. I plan to get an amp meter to check the output current, but if it says it's outputting the lowest level, I don't know what good that would actually be. Can you put a resistor between the cell leads and verify that the controller is actually outputting the correct current if the cell is bad, and not drawing enough current? Also, is there another high output SWG that I have overlooked? It seems most stop at around 1.4lbs/day. The IC60 and the resilience A7 cell that I would replace my current one with both put out 2lbs/day.
