I have two of these in my standard size 90 gallon reef, mostly sps. They are run on a tunze 7092 controller. They've been a part of the system for 9 months. Each pump comes with several voltage crystals that can be used to control the amount of power going to the pump, so basically you can dial it down or drive it up without the use of a controller. With the controller I can produce a nice wave in the tank. As far as flow these pumps replaced two koralia evo 1050's. There was nothing wrong with the koralia's, but even though they are rated very different, I have not seen any significant difference in the overall health, happiness and growth in the tank.
That being said I am very happy with the pumps. Depending on placement they will stir most of the detritus that settles to the sand during feeding and are noticeably stronger than the koralia's. With all things, you get what you pay for. I cleaned them for the first time after nine months, they come apart very easily, are very well built and after a vinegar water bath they basically wiped clean and look brand new. They are very quiet, but not silent, I would say the koralia's were just as quiet. WIth the controller you do hear them revving from stop to power if the room is completely silent. The titanium shafts and replaceable parts makes repairs easily if necessary.
Pros: well built, controllable, small, quiet, long power cord, very wide flow, strong
