Thanks Diana for posting here. The info about the clay is a mistake I was about to make. I have been soaking my soil and will have soaked it for 1 month before using it in my tank. I will update here if there is any good news about doing that. (mainly the ammonia problems I hear of.) If you read this Diana I am really looking forward to you visiting our club in Indianapolis in November. I almost waited to start my tank until then but I can't help myself wanting to do it sooner.
