Having never used an Apex, I wouldn't really be able to decipher that.
What I would generally recommend is something like our Interval 2, one pump idles at 30%, the other pulses every 3 secs from 30%-100% after 6 hours they switch. At night they lock in so one is at 30% and the other is at 100% or 30% as you feel is best and their is no more pulsing or change until light returns.
