Here’s my plan for fast cycling my new 55-gallon tank. I’d appreciate feedback on whether this will work. I have two goldfish in separate cycled 20 gallon tanks. I am running Aquaclear filters with sponge prefilters - one 50 and one 70. I plan to add a second Aquaclear 70 to one of the tanks and let it run for a week or so. Then I will take the filter that has been running (assuming it has more bacteria) and put it on the 55-gallon tank and add some ammonia to the water and keep testing for a week or as long as it takes to be sure that the ammonia is clearing and my nitrites and nitrates aren’t going high. Then I’ll start moving their decorations and plants into the new tank over a couple of days. I could also scoop up some substrate (sand) to add to the new tank. Finally I will move over their airstones and everything else and add the fish. Does this all make sense? Will I have to wait for the nitrates to rise and do a large water change before adding the fish or will the cycled media in the used filter just take care of the ammonia and nitrites?
