I just started my first fishless cycle, and i've heard that I can jumpstart the cycle by borrowing the filter cartridge from my existing tank. While the two filters are not the same, I believe that I will be able to fit the cartridge from the established tank into the filter of the new tank. Once cycling is complete tho, will I be able to change back to the appropriate filter cartridge in the new filter without messing up the bacterial colonies and therefore restarting my cycle??
