It was time to change the aquoen filter in my 10 gallon which is cycled. I am starting a little 1 gallon bowl type setup for a few shrimp. It hasn't cycled yet but I was wondering if I put my old filter into the water for a day or so if it will help speed up the process? Or will it screw things up in any way?

Thanks!

Thanks! I figured it was a simple answer like this but I wanted to be sure.

The filter is an Aqueon (the cartridge with carbon in the middle that slides into a HOB) so I just have it resting in my bowl to hopefully get some BB into the system.

Do you have any circulation in the bowl?
If so, aim it at the used media. The bacteria need plenty of oxygen.

Are there shrimp in the bowl? If there is no livestock then keep the bacteria fed with ammonia or fish food. Even a bit of shrimp from the grocery store.

There is no circulation but there is ammonia, nitrites and nitrates in the bowl....all 3 were pretty high when I last tested. I think the ammonia reading is from the MGOCPM and snail poop. I suppose I could feed it with some fish flakes?!

And no shrimp or anything in there yet just a few snails.

With no livestock, do the fishless cycle. You can indeed use fish flakes as a source of ammonia. It takes a few days for them to get broken down, but it sounds like the soil is adding ammonia to the system, too.
If you check the ammonia daily, and it is around 3 ppm that is a good level to grow nitrifying bacteria.
Adding some circulation would sure help. Got a little, tiny air bubbler?

Hmmm no I don't but I suppose I could get one.

I have tested the water and it has tested for ammonia, nitrites and nitrates so it is going....was just hoping this would speed up the process a little.

I will check it again tonight when I am home.

Adding the cycled media will sure help. Will you be leaving this media in the system? Or will you be removing it?
If you do not plan on keeping the media in the system then I would slosh it around in the water a lot, and if it is sponge or floss, wring it out. Do all you can to dislodge the bacteria and drop it into the bowl.
I sure would add some kind of water movement while you are trying to grow the bacteria. They are high oxygen organisms.
