I have a k 38k gallon pool and i think it's time to replace my jandy nature2 (we don't use the metals side) with a new salt system. You say to double the size so what could I use? Seems every year we have issues. sadly we have little electrical knowledge. On open it said 172, 185,186 and we cleaned the salt cell and it said it again. So we cleaned the nodes and now it says 170 and it won't change.

This plus our jandy heater says upper hi limit... electrical is not our thing but I know replacing the salt system I could possibly budget for, just can't fix both in same year.

Thanks for all your knowledge.
