How to safely Replace a Filter?
Hey everyone. So I have a nice 10 gallon Ive had set up for quite a while. I recently decided to rotate the Dario darios I had in it into my "mini fish" 20 gallon with licorice gouramis, guppies, and corys. I plan on putting a betta and some corys in the 10 but Im also thinking its time to get a better filter for the 10 gallon. I purchased it as a kit that came with a tetra 10 gallon filter. It works well enough but isn't the strongest and i'd like a little more flow. I was thinking getting an Aqueon Quietflow 10 for it, but I was wondering how I could switch filters without the tank re-cycling.
Would I have to run both filters for a while? Or could I do something like, set up the aqueon and stuff the already established filter cartridge of the tetra filter in the back? I figure just taking the tetra out and putting the brand new aqueon in would probably cause problems. Also, would just getting the aqueon as an ADDITIONAL filter be good? I am having some algae on my anubias plants so if it would help that I would be very happy to do so.
What's a good method when upgrading filters?
