Just took a look at older bills and seems we are all over the place....from 2500 to over 10000 gallons. The 2500 was just Mike and myself, the 10000 was when the spa was a problem and it was filled over and over trying to get the problem solved. When my sister was with us this winter, close to 5000.
When the first set of Nova filters were replaced, they were indeed dirty. Set replaced in November was dirty, but not at all like those first ones.
We replace them once a year and have had no problems.
