Hi, Is there any difference in using ceramic rings vs pond matric to aid in biological filtration. I am not sure if my two wet/dry I will be using for my 750 tank will provide enough bio load, So I would like to add maybe some pond matrix under the bio balls or ceramic bearing. Anyone have any experience with either?
thanks in advance
I meant to say ceramic rings in the topic, the bearing came from a flash back to drag racing motorcycles.
