Well I'll be a guinea pig and test this filter.
Just received it yesterday and installed today. Set it up on an existing 220g tank to seed the media.
As many items you get today the instructions are slim so a beginner might have issues putting it together. No problem for me.
Media that comes with it not what I would use so replaced baskets of activated carbon and filter floss with bio-balls I had sitting around. (from my leaky Marineland C series).
Went together OK but not impressed with diffuser. Will probably come up with my own later.
Nice feature is drop the pump in the tank, plug in and away it flows (no priming). And of course no leaks at this point. Will update as time goes on.
