My filter cartridge is falling apart now i have to change it, but how do I do it? Do I just take the old one out and put the new one in?...or do I leave the new filter sit for a while in the tank?... http://www.petsmart.com/global/prod...63751&itemNo=13&Nao=12&In=Fish&N=2030140&Ne=2 ...i already took the carbon out , but whats the zeolite for?...do you have to reaplace it, like carbon? TIA
