Just finished putting my new Tunze 2100 x2 with 7095 multicontroller in my 180 gallon mixed reef. Needless to say, the owners manual is not very good . What settings would be good to achieve a natural back and forth motion that my SPS and LPS would enjoy. I know its hard to answer not being in front of the tank, but I don't really understand what "pulse", "Interval one and two" mean and how long to pulse? Also, the 4 knobs at the bottom that control the power of the streams, why is there 4 instead of 2? Thanks for any help!!
