do i put carbon in it or ammonia stuff? my tank isnt cycled yet so i dont want to put anything it in that will mess with the bacteria. please help i have to get everything either today or tomorow. also how often do i replace the things inside the baskets and do i do 1 thing at a time or all 3. if one at a time how long do i wait to change the next? thanks for your help!
these are the choices i have:
foam inserts
ammonia remover
biomax
carbon
clearmax
fine filter pad
prefilter
water polishing pad
zeocarb

I have a Fluval 303 and use Peat Moss on the bottom (I have hard water with a high pH), Biomax in the middle one and Blue bonded filter pad in the top.
