Seems like the only way to add additional outlet is either buying another power bar 5.1, or splitting some device to single outlet on my 8 switch strip.I'm not familiar with the 0-10v input on the Abyss pumps, but most pumps when input turns to 0v, it'll turn off the pump. If the Abyss works the same, then I'd say you can free up a controlled outlet and move the A200 to the power strip.
