Programming Apex for 2 opposite gyres in tank to work simultaneously for ramp up/ramp down

Hi. I have 2 gyres connected to 2 icecap Apex interface modules (purchased from Coralvue) connected to a variable speed outlet from the Apex. Can you please send me an Apex programming code to allow the left gyre to slowly ramp up from 25% power to 60% power over 30 minutes, then stay at the full 60% for 30", and then ramp back down to 25% over the next 30". Simultaneously, the right gyre will do exactly the same thing, but in the opposite direction. So, when the left gyre is ramping down, the right gyre will be ramping up. So, when the right gyre reaches its maximum of 60%--staying at 60% for 30 more minutes, the left gyre will be back at its minimum of 25%, and stay at 25% for the next 30". Then, the right gyre will ramp back down to 25% as the left gyre ramps back up to its maximum of 60% over 30", and then stay at 60% (while the right stays at its lowest level, 25", once again) for another 30". In other words, the left and right gyres will act as mirror images of each other, doing the opposite of each other at all times. This will just keep repeating itself all day long. Thanks!
