who fill their own carts with liquid. Actually two questions:
1. How often in general do you put in fresh filler material after topping off a cart for a while? Once a day, once every two days, etc
2. How often do you just throw out the filler and put in new filler after you have rinsed it and reused it for a while? Once a week, once every two weeks, etc.
Thanks
