terri_ann,

Glad the AF is working for you.

No sure what size your system is, but I wouldn't change more water than 30% at one time. If you need to change more, than use smaller multiple water changes to be on the safe side & give any heavy metal build-up time to allow the organics to tie up the heavy metals into a safer form.
