Richard - I understand that you presently are using tribase carbon in a fuge with a great deal of success. I have the perfect 40g set up to try the same. can you tell me where to get the carbon ;)

We are building a ~ 300g system so i am going to plumb it to try the aerobic process. My plan right now is to use a series of PVC tubes to contain carbon and PH rock. I will install them horizontally over the sump and plumb them so that i can backflush during water change or into a micro mesh sock. Do you think that you could get Snake to offer advice in this thread?

Also do you know if the same bacteria cultures are in the Coral Food?? Does the coral food help the carbon bed activate faster??
