    Autopilot SWG% - Compensation for Water Temp

    Hello,

    As we are waiting for our safety cover to arrive so we can close our pool, I am doing slight maintenance on the pool to avoid any algae from growing b/f we close up in 1-2 weeks.

    The pool temperarture is around 62-64 during the day. The FC was around 3.0 the other day and dropping slowly day-to-day, so I was going to increase the chlorine output by increasing the purifier level. When I go to increase the purifier level, it only reaches 63% and will not go any higher. Even at the 63%, the purifier would not turn on yesterday, today it is on, but still only at 63% max.

    Is this normal since the water temp is so low or is there something else I am missing here that would prohibit the purifier getting any higher at this time? I did call customer service and they explained to me that the SWG compensates for lower water temperatures, but they did not say if it will only increase to a certain purifier% b/c of the low water temp.

    Thx.

    What you describe is normal. As the water temperature goes down they lower both the current setting and the max percentage it can be set to.

    Thanks JasonLion.

    I guess I should just turn the purifier down to 0% then and add some chlorine of my own.

    With the water temp at 62-64, how slowly does CL dissolve/dissipate? My CYA is still at 70. I am just wondering if I shock now and close next week, if my CL levels will be within a suitable range by that point.
