I wish I knew earlier. This thing is as strong as the Tunze higher models for 1/3rd of the price, and absolutely stronger than a single MP-40 without question. I almost don't want to hook it up to the Apex for fear of possibly losing the wave modes. Good thing I have an extra one to play with.
I set my power supply down to 12v, and one pump is perfect for night mode on a 6ft 125 gallon tank. I didn't even hook up the resistor to automatically do it. No need, plus the controller is going inside my stand anyway.
If I get it working with my Apex tomorrow, I will post a tutorial. You'll need a spare CAT5e ethernet cable, a 0-10v converter, and beginner soldering skills.
