Using a second hand filter #1
I have set up my tank, and am awaiting the ammonia to arrive so I can start cycling. Water has been in for 48 hours to clear chlorine, and I have done an ammonia test which was clear; so I understand that means the water wasn't cloranimated.

I inherited a Fluval U4 filter, but when I picked it up, the tank was empty and had been for some time, so obviously the bacteria won't have survived. Should I therefore give it a thorough clean and buy new filter material, so as to start anew? I'm a bit concerned about not thoroughly cleaning things, in case they carry something I don't want.

Also, on the subject of filters. I have seen lots about venturi - is there a guide somewhere as to which fish want/need the verturi added?

Thanks

Re: Using a second hand filter #2
Clean it up and get new media. Regarding a venturi, as long as the filter output disturbs the water surface there's no need for a venturi for any of the typical community fish.

Re: Using a second hand filter #3
Thanks. I'm glad my instincts seem to be right.

Ammonia has arrived today, so cycling begins in earnest.
