No, but I would be cautious. Seeing that the controller uses two 120-v plugs, that tells me you are controlling two 120-v pumps submerged in the tank and this just reminds me of the many mishaps we used to have in the hobby back in the day. I cannot tell if the controller "dims" the pumps or just turns them on/off. The head unit appears to be too small to be a VFD type driver, so I need more info on how it works. However, if it is simply on/off based on a timer, I would avoid this. Too many lessons from the previous decade to be learned there. 120-v pumps just do not do well when repeatedly turned on and off. I have fond memories of cracked motor housings, tripped GFCIs (you will have one right?), and in the worst case with the Rio Taam Pumps...the dreaded oil slick and a 20-gallon tank with everything dead. Been there, done that, not going back hahaha.
