How to change filters in an established tank?

[Deezoo]

Hello. I am using a sponge filter in a 10 gal. tank with 1 axl. It works good but I was thinking of changing to a submersible filter (fluvel) How do I add the new filter ? Can I just take out the sponge filter and replace it with the new filter or will that stress my axl? There are 2 fake plants and a few large stones in the tank, but I am worried about the bacteria for the new filter. Should it be run in another tank first ? Thanks for any advice. Denise

Can you run them both at the same time in the tank for a while?

The sponge filter shouldn't create much disturbance & if you use the spray bar option with the fluval & angle it against the glass it should be fine

I'd do what Nikki said. I'd have them both in there for a while so you can give the new filter time to establish and not have to worry about your water.

Ok, thanks so much. I can do that. :happy:

Perhaps have both going long-term...That way you have plenty of biological filtration, as well as a decent source of mechanical filtration. Hope to see pics of your tank soon!
