My 36 gallon tank just cycled completely and I purchased a 5 gallon tank yesterday for my betta and have never used already cycled media. I was wondering how that works. I currently have a tidal 55 filter with 2 big bags of matrix in it. If I take one bag out and put it in the 5 gallon tank will that hurt anything by taking it out of my main tank and how long do I leave it in the new 5 gallon tank before adding it back to my main tank? sorry like I said ive never done this before so looking for advice or tips.
