Fuge light

So i been battling GHA for about a month or so. I went out of state to texas for a family emergency. Everything in the tank was happy and doing great. Came back and green hair algae took over. So I tried everything gfo carbon water changes and even tiny bit of carbon dosing. When I had the reactor running i couldnt close the door to the sump so at night i would torn my fuge lights off because they bugged me being on at night. Well for the past week I haven't really been home so I left the fuge lights on and i accidently left the main display lights off for 2 days. well the cheato growth exploded and now 90% of the GHA is gone. Guess lights out trick works as well as having a fuge light on 24/7. So question is who leaves their light on 24/7 and who does the opposite of the displays?
