yeap will work, think is ur lights that cook your tank. like what bluesotong suggester, you can call chilldown or simply DIY it yourself. can get it quite affordable at simlim tower.
and btw, aquarium computer is recommended if you want to shut off/ turn on more things when things go wrong.
for example: if temperature goes abover certain level, lights and non-essential equipment off or sub chiller/fan turn on, alarm buzzer on.
with those computer, you can set it that way.
