Fish Fanatic
Ok so i have my trigon 190l and i am going to be setting it up at the weekend and moving my fish out of the 110l into the new tank. As the new tank won't be cycled i will also be moving my eheim internal filter into the tank. My question is how long will i have to leave that filter in there before removing it? I have no idea how long the bacteria will take to set up residence in the juwel filter.
