Changing filter cartridges om biowheel 350's

[ajcile612]

Recently had to change out all of my filter cartridges in my two filters because I could no longer clean them anymore. Will my tank go into a mini cycle because of doing this?

With the bio-wheel especially I'd have to say no

When I do mine, I change one side, one week, then the other two weeks later.

I haven't ever had a mini cycle occur from doing that.

Thank you. I ended up changing them all because I couldn't get any to clean out good enough. Water looks perfect after! Thanks for the help!
