We have had our pool for three years. Last year we had problems with our Aqua Plus Control System. We replaced two circuit boards. The warranty installer said he would not reccomend Aqua Plus to his clients anymore, he had scores of them going bad. Now this year we have low volts reading on our chlorinator. We checked the chlorinator cell and it is clean. The warranty repairman said we would probably need a new chlorinator cell, but eventually we would need a new system. Please help !
