Greetings all,
I just replaced a Red Sea sump pump (Sicce rated at 7000/lph) with the Vertex V6. I was very surprised that the volume/pressure at the return nozzle is about half of what I had. I even had to turn off my reactors to direct water to the tank, and still the flow is not enough. I do have to say that the pump is dead quiet, but there is no way its pushing even 1/2 of the rated 6000/lph. The problem with buying these pumps is you don't know what they will perform to until you buy them, and then your stuck with it, no returns on used pumps. I was replacing the red sea pump purely on the noise factor, it is noisy. Anyone recommend a quite pump for 6000/lph? I was now thinking the abyzz A100, or red dragon RD3......
