Nitrogen Cycle problem...

[Gourami Swami]

what media is inside the filters? All filters, even built in ones, should have some mechanical filtration (pad, sponge, etc) and some biological filtration (surface area for bacteria to grow-usually plastic balls, ceramic rings, etc)

What you need to do is transfer some of this from the established tank, to the new tank. It should be pretty easy to either cut a piece of sponge or take some of the bio media, and put it in the new tank's filter.

They are built-in filters. Which is why I was about to reply that I can't fit the tank's filter with the on for the FH's because they're two tanks with different lengths and widths.

Hello; Any way you can just move the established filter to the new tank setup. Then put the new filter on the old established tank. That way both tanks will be seeded with bb colonies.

He is saying they are built-in filters, so can't swap them tank to tank.
But the stuff inside the filter; the pads and bio-material, should be easy enough to swap.

hello; I get this part now. Can't say I have ever seen a built in filter. A new one to me. But yes what you call for seems very possible. Thanks for the clear up.

The filters are sponges. The one on the 50 gallon tank is huge and the one on the 25 gallon tank is just small. I don't want to cut a part of the huge tank's filter. Is there another possible way I could do it?

Maybe post some photos, they help a lot!

Hello; Being both are sponges it has been my experience such can be removed. If this is the case then just move the sponge from the established tank to the new tank. It does not have to be hooked up only placed into the water. Perhaps best where some water circulation is but this should not be critical. All you are trying to do is get the new tank seeded with bb.

By seeded I mean some live bb on the old sponge will move onto surfaces in the new setup and will begin to form colonies. It will take some time so the old sponge needs to be in the tank a while, say three weeks.

If you do not want to cut the sponge then use it whole.

first tank is a 40 to 50 Gallon tank that has 1 Red-Tip Arowana and a Janitor fish

second tank is a small 15 to 25 gallon tank that has a Flowerhorn named Camillia.

first tank is now with me for about 2 years now

Do I have to do a Nitrogen Cycle on both my 50 Gallon tank and my 25 Gallon tank?

Get a liquid test for ammonia, nitrite, and nitrates

If I do this once do I not have to do it again?

Once it's cycled it should stay

50 gallon has had the arowana in it, the cycle probably completed itself. If the flowerhorn tank did not have fish in it the whole time before the flowerhorn, then you will have to cycle the flowerhorn tank.

FH tank was given to me about a year ago but never really was used, this means I have to do the nitrogen cycle for this tank

50 gallon has had fish in it the whole time, then it should still be cycled. If you took all the fish out at anny point, then it probably is not.

only took out the 3 oscars and the janitor fish for about 4 hours

that won't have been enough time

hello; These last two highlighted bits tell the tale. Both tanks have had lots of fish in them except for the very brief time of four hours. So both tanks should be cycled and you do not need to worry about it any more.

The way to check is to get a test kit as was already mentioned and test the water. That will tell the tale.

He is saying the 50 gallon has been set up with fish but the 25 gallon has not been. So he will have to cycle to 25 with the 50's media
