What mode do you use on your Vortech pump?

When I had only the one MP40 I think I ran it in short pulse at the longest interval. I aquired the first one just before they came out with the Gen 2 version with Long Pulse and Night Mode etc. Almost a year after getting the first one, I finally got my hands on a second one which was Gen 2. So I was able to update the firmware on the original pump and now run them in Long Pulse mode, master/slave at about 75% power and approx 10 second interval. They are mounted on opposite sides about 3 inches below the surface. I've tried some of the other modes but settled on the Long Pulse setting since it works well for my 4 foot tank. Great flow, not overwhelming, with a nice back and forth circulation, undertow, surface agitation. The output of a largely empty (carbon only) Rena canister filter shoots across the center of the tank near the surface creating some random eddies in the flow there.

I tried the short pulse mode on nearly its slowest setting and it wasn't to bad but I like the reefcrest mode best. It really moves alot of water and picks stuff up off the sandbed with the undertow it creates.

I am pretty new to this pump, so I may not be the one to answer, but if you can afford it, go for the MP40, this way you have all the power you need, you can dial it down and if you upgrade your tank, you don't need to upgrade the pump

It is about $150 more from the MP20 to MP40, if finances allow, that is what I would do.
