Having read various recommendations on media, I had understood that course foam media should go before ceramic bio media, which could even go last?
I wasn't sure whether my filter was top-to-bottom or bottom-to-top, so I RTFM'd.
The instructions clearly suggest bio-media should go first.
Your thoughts?
