Unfortunately, the dynamic range of a vortech has the potential to be good and piss poor.
It can be set from 3000-1000gph. But 1000gph is the hard minimum. So if you need to run it normally at 1000gph...and you want feed mode, the pump slows down to....1000gph. If you want to do a pulse or reefcrest or wave, the pump will slow down to...1000gph.
The vortech shines when you can run it at 3000gph, but that is a lot of flow for some and not much for others.
That all said, I am considering buying one and not sure if I should get the MP40w or MP20 since I have a 40g (36x15x16H). If you own a vortech, what are your thoughts? What flow rate do you have your pump at in what size tank?
