Just double-checked. The COR15 only runs off 1LINK, so you need an Apex. The COR20 runs off a standard outlet - so it can run with or without an Apex (though to control it you need an Apex with Aquabus).

That’s nice to know . I’d go with cor20 then

Nobody mentioned yet that the cor20 is so quiet that you won’t even know it’s on unless you check the power bar on the module. It’s insanely quiet

I've heard that about the COR pumps. I'm running a Sicce ADV 9.0 myself, but I don't have any frame of reference or comparison between the two. My Sicce seems fairly quiet as well, the 5-year warranty is hard to beat - and you can now control it through the Apex as well with a firmware update.
