Hi Diana, I just read a post of yours from 2012 regarding a fishless cycle to start a tank. I did do this years ago on a non planted tank with an Aquaclear filter ( it was a science project for my daughter)but am getting ready to start a new 46 gallon bow front which I will plant on eco complete fine substrate. I also will have a new XP3 filter. Any /all suggestions are appreciated! I do have some established media but it is in my Aquaclear 50 which is filtering my non planted 25 gallon. That tank has small river stones on the bottom. Can I simply put some of these in a stocking and place them in the tank during the fishless ammonia cycle? Thanks!
