Nitrogen Cycle problem...

  • We are currently upgrading MFK. thanks! -neo
The whole point of the nitrogen cycle is to establish bacterial colonies in the tank that will convert the fish waste to less toxic forms. In order for that bacteria to grow and survive, there needs to be fish in the tank giving food (waste) to the bacteria.
But really.... read about it here https://www.fishlore.com/NitrogenCycle.html
much easier for you to do some research and then ask questions about it, than for me to try to educate you 100% on it in forum posts.

If the 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.

I only took out the 3 oscars and the janitor fish for about 4 hours. Does this count as the cycle being canceled or removed?

No, that won't have been enough time. Would probably take a few days to a week for bacteria levels to drop. cycle should be good as long as the fish were in there for more than 4 weeks

That's good. I'll do the cycle on my FH. Right now she's doing well. she's swimming around whenever we don't pass by her tank. She hides behind the decorations whenever we do so. I'll take out the other tank's filter and squeeze it into the other tank's water and hope that the filter's goodies will mix in with the FH's tank.

Hello; I would not do it this way. You are mostly going to be adding trapped detritus ( tank trash) this way.
I know you have not had time to read the link I posted a bit ago but strongly suggest you take a few days to read thru and digest that information.

The bb make a sticky film (called a bio-film by some) on solid surfaces. There may be some bb in the trapped detritus but likely more on solid surfaces. Were it me I would try to find some surfaces to move from the established tank.
 
Better than squeezing out the detritus from the old filter, take the pad in the old filter and cut a nice chunk of it off, then stick it in the new filter and leave it in there.

You could just stick the whole used pad in the new filter, as long as there is bio-media in the old filter which will stay there, to make sure you don't cripple the old tank's bacterial population.
Hard to say without knowing what kind of media you have in the filters, what kind of filters they are

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.
