FYI - if it makes a difference to any of this I have a Jandy Aquapure 1400 SWCG.
Is the controller for the SWCG smart enough to know when your pool pump is running and adjust for this? (I am guessing no even though it does have a flow sensor).
What I mean by this is that if you have your SWCG set to 50% and your pool only runs 12 hours per day is the system smart enough to run the cell 100% of the time since your pump is running only 12 hours per day?
If I am correct in assuming that it doesn't adjust for this that means that if you have your SWCG set at 50% and your pump runs for 12 hours per day then you are generating Cl for 6 hours per day. So the less that your pool pump runs the higher setting you need on your SWCG.
Will this shorten the life of your salt cell? Let's say you only run your pool pump for 6 hours per day and you have to set your SWCG at 100% to have enough FC. Is that worse for the cell that running your pump 24 hours per day with the SWCG at 25% - in the latter case your cell will be cycling on and off and likely won't run for that long continuously.
