Post a set of test results and how you got them.
We have a 24' pool and use about a quart a day with 50 ppm CYA. You should use a little more than that.
If your CYA is a little low you would use more, but from your statement you're using about normal.

What loss per day is your demand figured on? If I have done my math right it looks like 1ppm. 12*12*3.14*4*7.5 = 13,565 gal. or 1.7 million oz. 1 quart of 6% has 1.92 oz. of chloine. I seem to lose 2 to 3 ppm per day.
