"i've never heard of this. once a tank is cycled... (the bacteria usually live in the gravel and inside the filter as well as on the plants and lastly some in the water (although only minor amounts are actually in the water). In a new tank... brand new or a completely cleaned tank (gravel washed etc) then a cycle takes approx 6 weeks to complete depending on the amount of fish you have to cycle your tank."
Yep! Agreed! :P What I was trying to get across is that when you stir up old substrate that has not been maintained properly w/ water changes etc... you can release nitrate? pockets.... So, what I was getting at was that because everything was mixed up during the move, and receiving such a large amount of new water, etc... that the tank is going to haft to restabilize.... At least that's what I always understood!?!? :confused::oops::confused:
