Tunze Nanostream Pump 602 (660 GPH) or Hydor Koralia 4 Pump (1200 GPH)

[Carrera75]

Lately I have been thinking about replacing the 2 MaxiJet powerhead in my reef tank for a Hydor Koralia - 4 Water Pump (1200 GPH) but I wonder if this would be too much flow for the tank.

I have heard good things about this Hydor Koralia pump and it is cheaper than Tunze Turbelle Nanostream Pumps. Do you guys think that it would be ok to replace the 2 Maxijet PH for one Hydor Koralia 4 Water Pump (1200 GPH) or should I go for the Tunze Turbelle Nanostream Pump - 6025 (660 GPH).

Cheers
