I have the varios 8 and love it! Even at speed 1/5, it's pushing more water than my mag 9 did. Very quiet pump, I like that it has the slow start instead of going full power when you turn the pump on or feeding mode off. I know the vectra can be programmed so there's a "minimum" speed so when you're in feeding mode, water doesn't syphon but since the varios is already apex capatible, you can program it to do the same.
I haven't had time to play with programming it more with the apex but at least you don't have to buy any more hardware.
Varios also comes with a float switch and bracket so you can use it with skimmer cup or sump water level. It'll simply turn the pump off
