Bump to a really old thread:
So I just bought two wp-40's with the dual controller. I ran through a bunch of the settings and I really like this for the price. I have these on my 6 ft 125gal and on level 5 wp1 it makes a pretty good wave. I have a lot more nutrient export than I did before and if I put this on else mode. It's really stirs things up.

I know this threads a year old, but the 2 WP40's work great for the 125 gallon tank.
