Sicce is also a very quiet, powerful, low wattage using pump brand, made in Italy.
My original 180gal tank and sumps pump( a Laguna) was fried during a power surge a couple months back.
The Sicce I bought is rated at 1500 GPH.
I read really good reviews of the Sicce from reef keepers, the Sicce has been in service ever since, it is outrageously silent, and carries a 5 year warranty.
I was so pleased with it (and because power surges are so common here in Panama) I bought a Sicce powerhead as a backup, to retain circulation in the tank in case a power surge happens again.
They are not readily available here in Panama, and it took month to get it shipped here.
It is set up at the ready (unplugged) in case of emergency, or I turn it on when doing basic pump in the sump maintanence.
I used Mag Drive pump for years, reliable, and they are powerful, some give off heat, so in certain tanks a heater may not be required, or using an underrated one per size of the tank may be all that is needed. I usually put a sponge underneath them to deaden vibration, and even put sponges on plumbing near the pump that tends to vibrate.
