of course you can turn them down. but, why spend the money on mp40s when you could get mp20s to do the same thing? you're going to be turning them down anyway. and, you'd probably be turning down the mp20s, too, wouldn't you?
the mp40s give you upgrade flexibility, for sure -- but if you're talking about something for a 39g cube, wouldn't you agree that you're buying more than you need and more than you can reasonably use. if money is no object, maybe that's a different story, but when is money not an object? i'd rather save the $100+ per unit and spend it on frags.

Good comment above as to the flow pattern on the 10 vs 20. The same applies to the 20 vs 40.
Yes you can keep fish in a 39 with 2 X 40s', its called turning them down and alternating patterns. ie: waves!!
I am not trying to be smart but I want flexibility with everything I do. The more flexibility one has the better off we are.
