what kind of ornaments do you have....you mean live rock??? or do you have like a castle in there....if it is live rock the do it slowly as only replace one a month at the most depending on the size of the tank....if it is like a bridge or castle then replace no more then 1/2 at a time as most are hollow and have very little room for Bactria in the first place
