I saw a YouTube video in which someone used silcone to close up some vent slots in the filtration area. What is this done for ? I didn't bookmark the video. Thanks.

I believe it's to ensure all water flows through the filter media and so things don't get sucked into the filter media. If you do plug them up you have to make sure the water level doesn't drop below the filter grates at the top or the pump will run dry. I have a new fluval spec V and am deciding on if I should plug them up so I was doing a bit of research on it lately.
