How often do you change your floss?

[Westside Guy]

I have been using the Aquatic Experts brand dual density bonded floss in my Red Sea media cup and changing it every 4-5 days. My bio load is still pretty low, is it being changed often enough?

When it turns black, or when it overflows.

Every Monday and Friday, so 3 to 4 days.
