Tangster: so let me get this straight, you dont use any live rock in your tank. (eventually your base rock will become LR after time correct). As far as high jacking this thread, like Tangster said i do not care, the more information that people talk about the better for me, so that way i can read about what everyone else has problems with and how to do things the correct way. As far as needing LR in your tank to have ammonia, i bought base rock that wasnt very clean and there for i do have a die off and ammonia in the. I did although leave the rock in there for around 2 or 3 days then took it out and scrubbed it under water, it was starting to get slimmy and im sure that it wasnt a good thing. After scrubbing they are no longer slimmy. Again any information you have to offer is much appreciated on my side.
