short pulse mode all the way dude...pretty much the only mode I like...just because I'm all about the wave. Use the auto wave mode feature to set the wave. Only problem with this mode is the wheeening sound. It goes like this...


wraerrrr...wraerrrr...wraerrrr...wraerrrr...wraerr rr

if you speed it up... it goes like this:

wraer.wraer.wraer.wraer.wraer


lol

Nutrient Export mode is another good one for SPS lovers but I don't know, I like to see my over priced pumps at work and that can only be done by staring at the controller and it's nice flashy lights or by running the short pulse mode for the wave
