Vortech and lights out period

I am needing to go lights out for 48 hrs. I am wondering if it is possible for me to put a sheet over the mp10 for the 48 hr period. the way it is draped over the tank now is that it is covering the motor to the mp10.

Lights out means turn off the lights. You don't have to tarp off the tank or do anything else.
the motor does get hot running at full speed you might want to switch it to lagoon mode to reduce the heat. Mine gets fairly hot in wave mode but in lagoon i notice a big heat difference.
