I have bought a 4 feet tank.
I already had a 2 feet tank running about one month with 5 clowns loaches and 4 panda corys.
I want them to move to their new home.(the 4 feet tank)
I am going to transfer the two external filters from the old tank to the new tank.
Would you please tell me I still need to wait a few weeks for the new tank to set up its cycle??
set up a cycle

Seconded. If the two filters are powerful enough to run the 4ft tank, you'll be fine.chefkeith wrote:I'm not sure why people call it cycling the tank. In reality, you cycle the filters, not the tank. If you move the filters to the new tank, that's all you need to do. Just be sure the filters can handle the bio-load of the new tank.
The beneficial bacteria are now living in the filter and on the gravel of the established tank.
If you move all the filters and all the gravel (plants, rocks, driftwood...) to the new tank you have moved all the bacteria.
DO NOT WAIT. You will starve the bacteria.
Move all the fish right away.
If you do not want to move all the fish, but your goal is to keep some fish in the old tank, and move some to the new tank I would do this:
Keep the gravel in the old tank, and some fish. Put a new filter on the old tank.
Move the established filter(s) to the new tank, and move some of the fish.
If these are the wrong filters for the tank sizes then just move the media inside the filters. Old, cycled media tot he new tank, new media to the old tank.
About half the nitrifying bacteria are living in the filter media. The other half are on all the other surfaces of the tank, especially on the upper layers of the gravel.
By splitting the population of bacteria and splitting the fish population about the same proportions you are keeping both tanks cycled for the amount of fish that are in them.
The numbers are a bit rough. To add some more insurance against ammonia or nitrite add as many live plants as you can. The light needs to be decent for the plants to help out (about 1 watt per gallon minimum, or some sunlight). Plants are even better at removing ammonia than the bacteria are.
Give both tanks a few weeks to re-establish themselves, and check the water for ammonia, nitrite and nitrate and do water changes as needed.
Once things have settled down you might be able to introduce more fish to either tank, but this depends on the current population, of course. When you add more fish GO SLOW. The bacteria population has stabilized to meet the needs of the fish currently in the tanks. When you add more the waste level goes up, and the bacteria need to grow to match this new level. While they are still not up to the new level ammonia and nitrite can show up.
For a totally other way to cycle the new tank look in the Fish Health and Disease Forum for a sticky called Fishless Cycle.
You could take a small amount of the media from the established tank (not more than 25% of the filter media) or a handful of gravel and fully cycle the new tank with no risk to the fish.

38 tanks, 2 ponds over 4000 liters of water to keep clean and fresh.
Happy fish keeping!

I got two external filters.
The old one is Eheim 2224 and the new one is Kotobuki SV-9000.
Volume of the the new tank is 50 gallon.
Once I bought the new tank, I put all the fishes in a 5 gallon bucket.
Two days later, I put all the gravels of the old tank (washed with tank water)and with three times of new gravels (washed with tap water)into the new tank.
The plants,woods and stones are newly bought.
Then, I changed the water 50% everyday.
I first put some Nutrafin Aqua Plus Water Conditioner into the tap water before I pour them into the tank.
Afterwards, I put some Nutrafin Cycle - Biological Supplement everytime after water changed in these days.
Today is day five.
Is today a good day to put back all my fishes to their new home?
Or I still need to walt for one to two weeks?
Clown loaches and panda corys are very sensitive.
I don't want they get hurts.
