I got an MP20 and added it to my 65 last night. I'v always had a Korallia 4 driving water along the bottom/back of the tank behind the rocks to keep water and debris from stagnating back there. The new MP20 is positioned about 2/3 up from the bottom and toward the front of the tank, driving water across the front of the reef. That water encounters streams from my two returns, driven by a MagDrive 12. This should give me more than enough circulation for my LPS (with a couple of SPS) tank.
The fun thing for me when a Vortech pump is added is that, initially, you wonder just how much water its moving. It takes a few hours for the pump to get the body of water moving and completely changes the flow dynamics in the entire tank. The MP40 I have on my 40 breeder did wonders for that tank when I installed it almost three years ago. I'm counting on the MP20 to do the same for the 65 in the next couple of months.
