How loud is the hygger and do you know how much power it uses? I'm setting up a 550 and have been looking at pumps on paper from syncra silent series to abyzz series; i have a bit of concern over noise and power drawl. The abyzz is insanely expensive so I'm not likely to use it but the power drawl listed for it is quite low per gallon and all reviews claim it is dead silent. I have a syncra 3.0 and 4.0 and they make a bit of noise (though not as much as the water rushing through the test tubing; but their power draw is not exactly optimal (i'm setting up a number of tanks and total number of pumps I will require is approx 16,000 gph).
