So my questions are 1) is it ok to just add the new filter in since there is already a cycled filter in the tank? and 2) i see these come with carbon filters that i don't want to use, i'm assuming the bio wheel filter is all that is necessary? 3) do i just clean the biowheel in used aquarium water and put back as i do with my cascade filters?
Also, I am currently treating the tank with PraziPro if that is relevant.
1) yes it's fine to add it. It won't effect the cycle.
2) yes. Just the bio wheel is enough.
3) yes. Use bucket of tank water and swish it about to clean off junk.
The prazi will have no effect.
