I just purchased and received a 10lb shipment of the Australian premium live rock from Eric. It is gorgeous with varying colors of Coraline algae! Some other biodiversity on it that I am not sure of, but no pest hitchhikers that I can see. I currently have it in a 10 gallon holding tank, and was planning to use it to seed an upcoming 125 gallon tank that I am going to set up in a couple of months. That being said, I think I am going to have to buy more, as now I can't imaging using anything else for the rock work in my new tank!
Something to note, and has been said before on this thread, is that the rock is very lightweight and has a complex, delicate architecture, so 10lbs goes a long way and fills up a significant portion of my 10 gallon holding tank as shown below.
Still trying to decide whether or not to keep this in the holding tank and let it cultivate it more or add it to my current system either in the display or sump. Main concern is if adding It my established system now, the competing bacteria from established system will harm the current biodiversity on the Australian rock, so if anyone has any insight into this would appreciate it.
Thank you Eric for a great shipment!
