Thanks Eric.
The more time I spend looking online and talking to people the more I am starting to think the vortech / tunze / hydro debate is more to do with what's COOL then anything else. Vortech does have the battery back up and thats a plus but apart from that I just cant see any advantage for it on a large tank, smaller tank ok yes the wave motion looks good.
My thinking now is its like BMW drivers and ford drivers, both do the same job, both work, one comes with the I am cool appeal the other not so much.
Marketing is taking over this hobby, time will tell it that's a good thing.
