I am running a XP4 on a 90 gallon central american chilid tank. WHat is the correct placement of media in the 4 baskets?
A: See a very good diagram of the Rena Filstar XP here. This is the XP3 but the stacking order is the same from the bottom. Foams on the bottom, bio media (stars or rings), BioChem Zorb or other chemical filters and microfilter on top.
