Are you wanting to suck the muck into your filter? That’s a sure way to clog your filter and reduce flow. Best use a shoo-in I to a bucket as you do a water change.something that will work with my 12/16mm eheim echo pro filter pipes.
Yeah, but it would go into a spare filter (to be only used for water changes). Not the one used for the tank so no issue with clogging that filter and reducing flor. By having the inlet and outlet in the tank, it would minimise water waste. I came across it within a Green Aqua video.Are you wanting to suck the muck into your filter?

So most people would use a syphon to hover the bottom while doing a weekly water change but you want to re cycle the water through a filter?
Something like this?
I have this from APS but have yet been too busy to use it for such. Out of stock currently
