Tips To Speed Up Cycle Of A Tank Upgrade

[jv24]

Hi, i am in the process of upgrading to a new tank, this as obviously going to need cycling. The Question is whats the best way of using my current set up to speed up the cycling process?
I have currently got an external fluval 205, so i was thinking of using some of that media to help cycle the new tank. My new tank is a Juwel trigon with an internal filter. Any tips
Thanks

Set up new tank with both filters running and leave it for a few weeks to enable the bacteria to build up in the new filter.
Old filter should be able to sustain the same amount of fish even though you have a different tank.

Are you saying i could set my new tank up, get internal filter going. Then leave it a couple of days , then connect my external filter then add my fish out of my old tank into my new tank in one go?

You could setup you new tank with both filters and add fish straight away. As long as you are adding the same amount of fish as you had in old tank.

Need clarification from a more experienced member, but I am sure thats right.

Set up new tank with old and new filters. Put in water etc and add fish.
Leave old filter in for a few weeks to get the bacteria build up in the new filter.

Can another member please comment on this as Im sure Im right but could do with clarification.

Yes, this is correct. An established tank that has a fully cycled filter and has been running for at least a number of months will have a bacterial biofilter that has matched the bioload (the fish and other creatures) and the two (the creatures and the filter) are portable, they can move -together- to any new water volume (such as a new tank.) The old filter will continue to handle the old fish (no new fish or creatures should be part of this process of course.)

There will be a slight loss of overall numbers of bacteria because some of them live on the old tank walls and gravel but these are quite insignificant usually, compared to what is in the filter, so the moved filter will still handle the fish and will quickly move slightly upward in bacterial colony sizes.

Meanwhile, the new filter will (extremely slowly) begin to get a few bacteria become a part of the overall biological filtration. Eventually, after about a year, the two filters will have balanced 50/50 or so if you were to leave them both running. The balancing of the two filters can occur faster if you transfer maybe 25% of the old biomedia over to the new filter, still running both for a long time. Never remove more than 1/3 of the biomedia from an established filter that still needs to care for fish.

Now there are other, completely different ways to accomplish the overall goal of course. Instead of sharing filters on the new tank, you can simply seed the new filter with 1/3 of the biomedia from the established filter and then perform a fishless cycle to qualify the new filter. The old filter will quickly enlarge again and still be taking care of the established fish in the established tank. Meanwhile you will be fishless cycling the new filter with ammonia and playing around with the decor of the new tank without the fish being in there yet. This is also quite a popular procedure among experienced aquarists.
