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

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

Is this for your 29-gallon tank?

Yes ..it would be for my 29 reef .

Hey Guy
I have the Nano stream on my 29g tank and works real well it gives a nice gentle current thru out most of the tank with no snow storms... on a side note the 1 nano stream will keep your tank cooler in the summer as it only uses 6W i think ? I noticed a drop of 3 degrees after replaceing 4 powerheads with the nano stream.
