MP40s - what setting do you prefer?

Not sure I have the latest version of the Eco Smart User Manual, but in mine the Auto-Tune procedure is on page 25, Section 4.3. It appears they only talk about a single pump there though. If you are using two or more, you will need to ensure they are in a proper sync/anti-sync, master/slave configuration. A pump on the back glass will not help and may in fact hinder the generation of a wave. On a 6 foot tank you may need two MP40s at each end, or a pair of MP60s to get a decent wave going. Even though you haven't had success generating a wave yet, the back & forth movement of the water with two pumps in short pulse mode should provide some sort of rocking motion in your livestock & may help flush detritus out of your live rock. Personally I don't like the wave mode since it's one of the noisier ways to operate these pumps with them ramping up to 100% & down to idle rather quickly in most cases. There is also a warning & disclaimer in the manual to consult with your aquarium tank manufacturer to determine if your tank can withstand the extra stress of water sloshing back & forth. I use the Nutrient Transport Mode from time to time & the waves created at the beginning of that cycle are enough to discourage me from using wave mode for very long.
