ug. I have a nano tank, and I have been battling dinos for the past few months. I have a 10-gallon nano tank, and I am wondering if it would be better to just get rid of the current rocks and replace them with live rocks from my LFS? Maybe the beneficial bacteria on the new live rock will outcompete the small dino population left behind? I have been trying a lot of different options, and I am trying to avoid using chemicals in my tank.
