Questions on Angel Plus "Active" filter

I've been using an active MAG filter from Angel Plus to cycle a 5 gallon tank to great results (0ppm ammonia, 0ppm nitrites, and the presence of nitrates in ~4 days!) alongside a power filter. A few questions:

1. How long should I keep the Angel Plus filter in my tank before the power filter can get a good amount of bacteria and I can remove the Angel Plus filter? I have another tank I'm cycling and it'd be nice to speed up the process a little bit by dumping in the Angel Plus filter...

2. I'm thinking of cutting up some the active filter media and sticking it in my power filter. Would that work out well?

 

Welcome to Fishlore.

When using seeded filter media or sponge filters it can take up to 2 months for enough bacteria to transfer and seed the new filter and to become a stabilized tank. You could cut up the filter media and split it between your tanks. The smaller pieces would still help to seed each tank, just at a slower rate.

What is stocked in your tank?

I do not have experience with the Angel Plus active filters, but do have experience with using seeded media to transfer cycles between tanks. Did a quick search and found this thread on this Angels Plus product:

 

I currently do not have any fish in my tank. I'm keeping it fishless for a few weeks in case something comes up, just to be careful.

 

What is your ammonia source? Seeded filter media is meant to be used with a couple of fish.

 

I'm using ACE Hardware brand Janitorial Strength Ammonia as my source. When I do dump some fish into the tank, I plan on stocking slowly.
