Looks pretty good...your FC is a little higher than it needs to be, but won't harm anything. I would lower your ph down to 7.2 and repeat that everytime it gets back up to 7.8...these Muriatic Acid additions will also slowly lower your TA which eventually will reduce how fast your ph is going up.

How much FC are you losing each day?

I just comming off a slam ... I was losing about 3ppm a day , even with the pool solar covered. So i brought the FC up to 15 a few days ago. Its comming down gradually being 95deg here in chicago. I was a little concerned about the TA being 150. But ph hasnt been a problem.
