Hi All, I'm starting my first fishless cycle in a 38 gallon bowfront with a penguin bio-wheel 200. I read that I can use something from my existing take to jump start the bacteria growth. Is this something you recommend? I have a 5 gallon with 3 guppies, and a filter cartridge that needs changed, can I put that old cartridge in my new tank to start the growth? Thank you!
