I am setting up my 120 litre again as did shut it down.... Realise that my 240litre is over stocked so doing a transfer.. Can i use a few litre of water from 240l to jump start the tank, will i still need to do a cycle as new filter will be use and gravel too... In this tank i want to know if a red fins shark be happy or is it too small for it? Can leave him in the 240l and move a shoal of fish instead but wanted to balance out the group of fishes and include a big ish fish... Thanks in advance
 
You will still need to cycle, the bacteria is in your gravel and filter media.
 
Sorry, I didn't see your using gravel too, but yes it probably will have to recycle but guessing it will be fairly quick opposed to not using your gravel :)
 
Thanks for that knew i had to cycle but wanted to double check... Any one know about the shark.... As am trying to work out what will be able to go into the 120 without overstocking and stressing them with the move....
