Uh-oh. I just set up my brand new XP-1 (and I mean 1 hour ago). I have coarse, medium and fine pads that came with it, along with the bio-chem-sorb pad. That fills up the whole basket. Since I still have my Bio-wheel filter going, my lFS told me not to remove it from the tank, but they had me buy the phos zorb pad and put it into the bio wheel filter instead of the carbon/sponge cartridge that it normally uses. (The bio wheel is still in use) Is this not the right way to use these filters?
PS I have very few plants, a 30 gallon tank, about 10 small tetras, 3 dwarf loaches, 2 sparkle gouramis, 3 small otocinclus, and 5 shrimp in the tank. For CO2 I have Flourish Excel along with a "Turbo CO2 Bio System". I also have about 2 1/2 watts per gallon of lighting and Eco Complete for substrate
