is it a must to have aerobic bacteria in your filtration for a reef tank? reason im asking is, i just got over a problem with my wet/dry biological media causing huge nitrate problems. ive been researching and asking questions recently and it seems like no matter what type of biological media you use in a wet/dry filter can cause nitrate problems. so in that case do i need to worry about having biological filter media in my wet/dry in order to grow aerobic bacteria.
don't know if this matters but my tank is 30gal with a wet/dry filter/sump that hold approx. 20gal. total 50gal. and i have 50+pounds of live rock and 40pounds live sand with tons of water flow. so im assuming i have more then ample amounts of anaerobic bacteria for a reef tank. i wont have more then 3inchs of fish. mainly invertebrates and coral.
the reason im asking is because like i said i had a problem with filter media which caused huge amounts of nitrates. so i took the media out. so now all i have im my filter is a filter pad in top of it where the water comes in to catch debris. so my plan is to use LR
in my wet/dry. im going to take it out of my tank which is newly cycled so the LR
is not pretty any more since the 4weeks of cycleing time. and put it in my wet/dry in the aerobic biological section. but i dont wont to do this if its going to cause nitrates like my old filter media did.
im sorry if im over explaining this but i want to make sure im clear. ive asked these questions at another forum and got "round about answers".
ps. how would u have aerobic bacteria growth with any type of filter besides a wet/dry?
