The aquarite can generate 1.45lbs of chlorine in a 24 hour period. This is equivalent to 1.45 Gallons of 12.5% bleach. So the maximum, your SWCG could put in the pool running at 100% for 24 hours is 11 ppm. So if your running 7 hours at 100%, chlorine put in is 3.2 ppm. For 2 ppm, you would need a setting of 65%.

However, the numbers given above is what is put into the pool not necessarily what you would measure since chlorine is constantly used up. So to keep a certain level, you must run it a bit longer.

What is your current % setting?
