I just got my XP3 and I'll be ready to set up my new tank later to day.
It included 4 dark pads (I think it's 2 foam 20 and 2 foam 30 pads), a white foam pad (no idea), and I bought ceramic rings, and bio chem zorb.
In what order should they be in the fliter from bottom to top?
Do I use all 4 foam 20 and foam 30 pads or just one of each?
I'm sure I'll have more questions as I start.
