My pool build got finished up about 6 weeks ago and we added salt about 10 days ago. Since then I've been struggling to keep my FC < 8.
I note there is general advice about tweaking the cell and the pump time but is there a good rule of thumb about where to start?
My cell is currently running at 20% (it got started at 50% and I've been dropping it to try and control the FC) and still keeps the FC at about 8, CYA at 80. Salt is currently at between 2,800 and 3,000.
Should I set my salt cell to 50% and then reduce the pump times to keep the FC at the 4-5 mark? I don't feel I should drop the cell to less than 20% as clearly I have got my timings slightly wrong at the moment... I'm going off the assumption that it's best to change one thing at a time rather than changing the pump timings and the salt cell percentage. I started by dropping the cell down as I assumed it would only take a small change (I was wrong!).
The cell is a Hayward T-40 running through a prologic8. The pool is about 26,000 gallons so I would expect to have some leeway on the cell, just not as much as I'm seeing.
I'll run a full set of tests tonight as we've had a lot of rain today so some of my values may change.
Appreciate any advice on a good starting point.
