Current Tunze settings.
Powers heads alternate back and forth every 4 hours, and ramp up from 30% to the upper setting over 3 seconds when it's the active unit, otherwise it idles along at 30%.
Minimum flow is 30% at all times from each. #1 is on the left, #2 is on the right. #1 used to have a higher power rating but was blowing sand around. The left hand side of the tank developed a little algae on the sand bed so I upped the flow going that direction and it's been clearing up without moving sand. I'm sure I could probably still turn them up some, but I haven't worked at finding perfect positioning and settings for them since I added the 2nd one.
The 6105 pumps would really rock a 6' long tank. They're kind of big for my tank unless it was maybe full up of mature sps colonies creating drag.
