I am setting up an XP2 and trying to decide the most effective way to set it up if it is the only filter on the tank. The tank will be either 28, 29 or 36 gallons (depending on where I decide to put the XP2).
I have two different ideas:
2-20 ppi foams
-------------- bottom basket
2-30 ppi foams
____________
matrix
--------------
bio-chem zorb or purigen top basket
fine filter foam
or
1-20 ppi foam
1-30 ppi foam
-------------- bottom basket
matrix
____________
matrix
--------------
bio-chem zorb or purigen top basket
fine filter foam
Any thoughts on which is better? Would 2 foams (stock in XP2) instead of 4 (stock in XP3 & XP4) be sufficient?
Thanks!
