Hi,

You need to add some stabilizer and more chlorine to your pool. "bleachcalc" will do the math for you. Download it and put it on your desktop.

1. I'd recommend adding enough stabilizer to bring you up to 30-40ppm. You may decide to go higher later.

2. I'd also maintain the FC level around 3-5ppm. Consider chlorinating with a 50lb drum of Cal Hypo. It's very convenient and you need to get your Calcium up around 200-300 or so.

3. No lower on the pH....maybe 7.2 -7.6 would be a little better. Your Alk will come up along with the pH...that's fine.

None of your numbers are really BAD , but you'll get a Gold Star if you make these adjustments!
