Ok so after watching dustin's videos for a long time, I want to start my own dirted tank. I have the MircleGro organic potting mix and the gravel i want to cap with, and a bunch of plants. So i have some time before I want to set it up becuase the tank has fish and water running in it currently. I hear about somthing about mineralizing the dirt and stuff, so can anyone explain on that? Dustin also says that duckweed helps absorb the extra nutrients, will hornort work too? b/c i have a ton of hornwort in my pond, like enough to cover the 75gallon tank densly in hornwort. So, will hornwort help if i float a bunch of it? Could i just soak the dirt for a few weeks in a few buckets or somthing, so it wold leech off the bad stuff?

Thanks again.
