Mitch, I'm making the assumption that temp and pH are matched. And I'm directing the comment towards the bacteria count in the water column, not chemical considerations(although I stand by my statement).
While changing over tanks, I increased total volume from 60g to 160g (added 100g of seawater mixed that morning)AND I moved the sandbed. I tested for NH3 for 1 week following and did not detect any ammonia in the system.
