Thanks. That is exactly what I was wondering. I got confused because it sounded like people were saying that the bio balls actually created nitrates. What you're saying is that they help the nitrogen cycle but leave out the last step. That makes a lot more sense. I have a lot of LR
in my tank currently and a DBS. I don't think there is any additional room to add more LR
. I like the idea of replacing the bio balls with LR
rubble though. Is it going to be overkill to have a lot of LR
, a DBS, and LR
rubble in the filter. I don't see how doing everthing possible to aid the nitrogen cycle could be a bad thing, but just want to be sure. Thanks for the help!
