What would you do? Vortech or Closed Loop

[Ron99]

The nice thing about the MP40 is all the different modes you can program. Fast waves, slow waves, two variable modes to simulate either a reef or lagoon, feeding mode and also the night mode which powers it down to 50% at night. And I'm not just saying that because I'm trying to get people into the group buy

The other thing that looks nice to me is that the Vortechs seem to produce a broader and gentler flow than Tunze or Koralia by using a much larger propeller that spins more slowly. To me it seems like a more realistic and more natural flow than the produced by smaller powerheads etc.
