I realize there are many factors that can determine the outcome of my question but:
After adding a new filter to a cycled and established aquarium how long, on average, would it take for the new filter to have bacterial growth?
The new filter does have mechanical and biologic media.
I realize I can take existing sponges, biological media, etc. from the current filter and add them to the new
filter but I would prefer not to do that at this time.
I will be setting up another tank next week and was wondering if running the new filter for only 1 week (in an existing, cycled tank) would be enough time to help cycle the newer aquarium when the filter is moved into the new tank?
Please note I cannot just swap the filters as the established tank is a 55 gallon with a canister and the new tank will be a 10 gallon with a HOB.
