System flowing nicely… LooseCannon: What is the white oval box? Light controller? : Yeah, if your referring to the small white oval shaped plastic piece attached to the top right of the top box, that controls the intensity of the light — but it’s plugged into a wifi outlet that enables me to put the lights on a 12 on/12 off cycle.

I'm interested about pc fan on the top.
It's just a hole for the fan or filter used too between the the hole and pc fan?
Thanks
@John the principle of PC fan in monotub the same a ceiling-mounted exhaust fan in your bathroom. The PC fan works by PULLING the air up instead of the PC fan blowing air into the tub. So that it pulls old air out of the box while force the fresh air to be pulled in through the air vents, which is protected with polyfill/synthetic filters/sponge where it can be filtered.
