  • Great pump very noisy By on 12/9/2015

    I recently bought this pump for a 225g mixed reef and the pump is a work horse I have 1" returns reduced to 1/2" and the valve wide open, and it moves water. The only complaint I have is that it is noisy as all hell. It sounds like you are on a runway with airplanes flying over. Not vibration noise but wind noise coming from the cooling fan.

    I've been running this pump for a year and a half on my 210gal with two 1" returns to the sump, both of which are restricted down a fair bit (50% on one and 25% on the other) so it could have handled a much larger pump for the 5.5-6' of pumping height. This higher flow has allowed me to avoid any powerheads in the tank (money in the bank). A pump level higher would likely have been a good fit if I was running a hard coral only tank and needed very high flow.

    The only problems I've had are of my own doing. On the intake line you NEED a PVC or the heavy duty white flex piping as the braided vinyl will collapse under the force. Also, I had to take the impeller off to clean it out and found the construction to be much better and simplified over many other pumps I've had in the last 15yrs. An example would be that there is no shaft the magnet spins around so fewer parts to wear out.
  • Great pump but very hot By on 11/10/2014

    So I really like iwaki as a brand but in regards to this pump I feel like it simply gets too hot and has a bit of a noise. But overall the pump is very well built and looks dependable.

  • Replaced Reeflo HHG with this. By on 1/12/2013

    I replaced a Reeflo HHG that would never stop leaking at its shaft seal with this pump. It is about 7db louder (87db) than the HHG but that is a small price to pay for a water tight system. It has exactly the right amount of flow for my system, I had the HHG valved back. I am very impressed with this Iwaki, it is my first one and will not be my last.
