This is my first posting and not sure what my first move should be in correcting my water chemistry and possibly going BBB. Some background. Since 1994, I have faithfully kept my chlorinator filled with (10) 3" tabs each week and the results are ph @7.4, alkalinity @110, and chlorine @2 . I add 7 oz of leslies algecide and 4 oz to the pool water. In 1999, I was told water hardness was 680 and told to drain the shallow end and refill. During the 2010 closing in Sept, Leslies test said hardness @200, cya @99, total dissolved solids @1300 but the nitrogen & phosphates were so high that I should expect to drain all water from the pool in 2011 (may). They said my lawn service that fertilizes the lawn is responsible for this. I cover the pool with a solar cover so the pool could warm to 85+ deg weather permitting, and the pool gets full sun all day. Pool use is limited to 2x week since we travel more and spend less time relaxing. Suggestions ???
