I replaced it Sunday and it was overflowing last night.. I need to get more out of them... (This was prior to me adding my chemi pure) hence why either one bigger 7" would be better or two 4" and since I have a 4" already I am going to try to just add another.I have the 7" cup and have a bag for carbon and purigen in it. I add floss on top. Overflows when they get dirty. Try switching out more often.
