Is it 45w analog total or PWM total? I don't have any experience with the aquaero only with your flowmeter which I am still quite disappointed about the cable but if this is 45w total output analog that is quite impressive compared to what else is on the market.

I have a big ng which I run everything analog off of because it's much quieter but I have around 40w to much for it so every once in awhile it will switch to pwm mode to sustain the load. I think a 45w analog controller would certainly be able to handle my load and something I would consider purchasing.
