Hi all, I recently upgraded to a 210L tank from a 65L. I added the internal filter (Eheim) from the 65L into the 210L along with the Fluval 4 plus internal filter that came along with the tank and fish. I also purchased my first external filter an Eheim Pro 3 2180 which has been running alongside the internal filters for approx four weeks now.
I am not sure how long roughly it can take for the external filter to mature bacteria and when I will be able to remove the internal filters. I was planning on removing them one at a time and obviously carrying out water testing to keep a close eye on the ammonia content, but I really do not know realistically how long to wait. There is no real rush, and I would rather wait than risk some ammonia spikes, some advice would be welcomed!
Thanks in advance for any replies.
