I also like the blue and yellow mode....i think they are short pulse and tidal wave. What size tank are u gonna put it it? I use to have it in a 30 and it was the best. I now have it in a 40b and the performance isn't the same at all.
I have one opposite a Koralia 1400 in my 75g and it does a nice job. I think I have it on the purple mode right now, but I might switch it over to something else, not sure yet.
Tip* the way i center the wet side with the dry side, I set it in the green mode( constant current) very low flow and i put my ear to the tank and then i move either the wet or dry side around until I hit the spot with the less noise and vibration.
