| Re: NEW TANK on Saturday!!! I think what matters most are the surfaces on which there are bacteria, and the filter. The best such surface is of course your old gravel - imagine how much bacteria are in that gravel alone. There are also bacteria on the walls of your old tank, but obviously you cannot transfer that, lol. I think what you could do is use the established filter plus the old gravel to cycle the new tank fast. Even if it will be cycled very fast, there probably will still be a mini-cycle because you'll still have a decreased number of beneficial bacteria in that new tank, as compared to the number of bacteria you'd have in your old tank. If you want a completely new gravel, then you could put the new gravel in, and in addition put the old gravel (or at least some of it) on top or in some container if you don't want to mix it with the new gravel. This should help spread the beneficial bacteria on your new gravel. Also, if you have any decor in the old tank - you could use that too. |
