Thanks guys. My pool is not large, 14,000 gallons. I think the reason my pool requires so much acid is a combination of the water in my area having a high pH level and aeration due to the spill from the spa into the pool. It is set to return part of the water into the spa when the pump is running during the day.

As for my test kit, it's shameful but I am still using the basic test kit provided by my builder. I've been planning to order the Taylor K-2006 kit online since none of my local pool supply stores carry a FAS-DPD kit but just haven't gotten around to it.

Off to the pool store I go to pick up my combo brush. Wish me luck and thanks again!
