My father is staring up a 46g bowfront aquarium and wants to jump start his cycle with something from my tank. I have a 125g that has been up for about 2 months. My cycle finished about 3 weeks ago and I now have a few corals and 2 fish. I started off with a cannister filter until I build my sump and he is doing the same thing. Would it be OK to give him a few pieces of my bio media to put in his cannister to introduce the bacteria to his tank?
