How long would it take an XP3 to be seeded enough to replace an existing canister?
I'm looking to upgrade/replace the exisisting Fluval canister filter that I have on my 75g. I'm having issues with the Fluval and going to most likely swap it out with an XP3. The tank is moderately planted and fully stocked.
If I add the XP3 to the tank and let them both run, how long should it take for the filter media on the new XP3 to contain enough bacteria, that I can take the Fluval out of the tank and not cause a mini cycle or disrupt the balance of the tank?
I have pre-filter and biomax in two of the Fluval trays and would rather not move them to the new XP3. Again, just don't want to chance risking a mini cycle and killing off the stock.
