With CC of 1.5 it would be best if you can give the pool sunlight during the day and only use the solar cover at night. It would also be good to keep FC up a little higher (perhaps 23) till CC goes down to 0.5 or lower.
If you are using just a leaf net, it is best to clear out the leaves every couple of days to once a week. You don't want them sitting in the water for weeks. Any time you have the leaf cover up you might as well check at least the PH and adjust if needed.
