First off, I wish I had known about this site before I had started my tank. I used CC
for my substrate and have not been very happy with it. I am going to switch my substrate to sand. I have read some articles on the best way to do this. I plan to have my fish in my QT
tank so that I don't have to worry about them too much. My only question is, by removing the CC
that has a lot of good bacterian and such in it, I am going to cause another cycle by adding new sand? I was thinking about putting some of the CC
in a mesh bag and leaving it in the sump for a while so the bacteria can remain in the tank. I do have 80-90lbs of LR
though that will stay in the tank. Will I have to wait a while to add the fish back into the tank?
