Hi there.

Im busy cycling a 35L tank in my room.

We also have a 190L tank downstairs with external filter and in the tank we have:

  • 2 neon tetra's
  • 2 dalmation molly's
  • 2 blue gourami's
  • 10 rasboras
  • 4 peppered cory cats
This tank has been set up for around 5/6 weeks. Would it speed up the cycling process of my 35L if i was to remove the sponge(s) from the filter on the 190L tank and dip them into the water of my 35L tank, and squeeze them one after the other and then put the sponge back into the filter downstairs.

Obviously id need to check the water of the 190L tank to ensure ammonia and nitrite is at 0, and that nitrate is below 30/40.

The catch though, im cycling my 35L tank with household ammonia and its levels are around 3, nitrite levels are around 0.50. If i dipped the sponge in and squeezed it, wont the sponge carry some of these toxins back over to its filter and therefore into that tank (190L)?

Is it neccessary to dip the sponge of the 190L tanks filter into the water of my tank, or can i simply just hold it above my tank and squeeze it in. Needing advice. Im very impatient and want to speed my cycling process up as quick as possible.

Thanks
 
No, you don't need to dip it in the tank, just squeeze it. Not that you will get a large benefit...sounds as if your 190 isn't fully cycled. And it needs a water change with that nitrite level.
 
Just completed a 30/40% water change. Used a kettle to get the water the same temp each time. Will wait a few hours and then test.
