I have a 46g bowfront with about 38# of live rock, a PennPlax canister filter designed for a 100 gallon tank (w/ ceramic and carbon media), aqua c remora skimmer w/MJ_1200 pump, and about 40# live sand. I am getting ammonia and nitrate levels of 0 since I established the tank. my nitrates continue to climb despite weekly 10g water changes
live stock includes:
2x Oc. clowns
3x bluegreen chromas
1 bangaii cardinal
1 blue tang
1 royal gramma
emerald crab, cleaner shrimp, and 3-4 various snails, etc.
I read somewhere that having live rock coupled with another source of bio-filtration can cause issues with high nitrates (something about competition between the different filter's bacteria?). is this true? should I remove the ceramic and/or carbon from the canister? is the LR
and sand sufficient enough in their bio filtration?
Thanks in advance
