2x the length @ same body size...if the korallia is as small of body = 2x as big
You mean 'V' flow from Korallia and cone chaped of tunze products
And the 6025 is actually 730gph and not the reported 660gph, so one is stronger and one is weaker than reported.
*Oh, and i believe this is the tunze nano mod thread, not the korallia thread
