Tunze is roughly 1200 gph for about $90
Koralia is roughly 1400 gph for about $50
I understand people say Tunze is a better product with less failuire, but I have yet to have a Koralia fail on me or stop all together. So if you compare apples to apples, it's almost double the price. I would certainly use a Tunze for the right price, but as you saw Saturday I'm still trying to "dial in" my tank on the correct flow and direction. If I can get a 1400, or even a 1050 then I can get rid of the two Nano's I'm using. Koralia's just seem to be easier to come by is all.
Side note..thanks for coming by on Saturday. You should have stayed long enough to watch Brian get sloppy, fall down drunk and agree to start spending all his extra money on his wife instead of his tank!
Just kidding Brian!! I'd never let you get so drunk as to promise that..
