Gucci Gourami Posted June 24, 2021 Share Posted June 24, 2021 How long does a tank need to become seasoned with pre-cycled filter media? Link to comment Share on other sites More sharing options...
JuneDog Posted June 24, 2021 Share Posted June 24, 2021 I seeded my 75 gallon with a friend's media in a FX4 canister filter. Took just over 2 weeks to cycle. Link to comment Share on other sites More sharing options...
Patrick_G Posted June 24, 2021 Share Posted June 24, 2021 I’ve set up tanks with pre cycled media and immediately had an effective nitrogen cycle. I’m able to add fish right away with no detectable ammonia or nitrites. I’m careful to keep the bio load small in the beginning so I don’t overwhelm the bacteria in the pre cycled media. If we’re going by Cory’s definition of seasoned then it’ll take much longer as all the elements of the aquarium come into balance. 1 Link to comment Share on other sites More sharing options...
lefty o Posted June 24, 2021 Share Posted June 24, 2021 cycled, and seasoned being two different things. one can effect an almost instantly cycled tank. seasoned, idk but would say a month or two. Link to comment Share on other sites More sharing options...

I agree. If you are looking for something that depends on microscopic life form and biofilm such as shrimp in a rush grow lots of algae before you add them fan/bamboo shrimp my understanding is at least a year Link to comment Share on other sites More sharing options...
