Well I pulled the trigger yesterday and ordered the 130d. I'm really excited to get this. I currently have a 14 gallon Biocube and some years ago I had a put together 29 gallon. I will be using this thread to keep track of my MAX's progress. While I wait I will be clearing out a spot for it and start filling buckets with RO/DI water. I live on the third floor of an apartment and my filter system only get 40 psi. It takes forever to make water.
