What is the min flow on the mp40w vs the mp20?? I want to get one for my 30 breeder and it's an all lps tank. But i really the wireless of the mp40 incase i decide to get 2.

MP20: 500gph. MP40: 1000gph. Get the MP20. You can always upgrade later. Two MP40's on a 30B would blow your LPS into next week. I have one MP20 on a 3' 65, and my coral focus is LPS. The duncans, acans, scoly's & bubble mushrooms prefer the gentle back & forth linear flow, and the prop is big enough that you'll be moving a wall of water & still desedimenting in order to keep the crap in suspension. IMHO.

The MP40w min flow is 1000 gallons per hour versus 500 on the MP20. Jim's post above is pretty on point.
