Old Filter To New Filter Change

I just bought a new filter for my 10gal tank. I want to make sure I swich them over properly so I don't destory my ammonia cycle. What is the most safe and efficient way?

 

Run both filters at the same time for a few weeks. Or put all the old media somewhere in the new filter so it seeds it and keeps doing your biological filtration.

 

You can either transfer over the filter media or just run both filters for a few weeks till the new one is seeded.

 

Does your new filter have cartridges that will fit in your old filter?
If it will, you can put the new cartride behind the old one in the filter so that it creates a bacteria colony and than just add that cartridge to your new filter system

That's pretty funny! I thought you were the same person for a few minutes!

It is the Fluval C2. This isn't really room for the old type of filter media I have. If I run them next to each other roughy how long should they run together.

I would give it at least a week to collect enough bacteria I do this all the time with my filter cartridges, I change them once a month, and I leave 2 running together for 1 to 2 weeks
