I've set up a 100L tank in my bedroom in anticipation of a fish I'm collecting later today (hopefully some pics to follow later today ) and I'm using an Eheim 2215 external on the tank. My room is south facing and gets lots of natural sunlight, and now I see the green canister of the Eheim is quite translucent (which I actually quite like, being able to see the layers of media).
But I vaguely remember reading somewhere that filter bacteria don't like light. So, do you think the natural sunlight will inhibit the bacteria in the filter?
