Yes thats exactly what I do , A double fan blowing when the MH is ON thats why when the MH was on today the temperature didn't change.
but I am not sure if I run MH for 6hours the fan is good enough , I cant afford chiller I hope the fan do the job for summer

I find if you have a canopy, and you build fans into it, it seems to contain the heat and expel it faster. Kind of like a heat sink in a computer... I only have the fans turn on when my MH go on, seems to keep the tank temp stable. How many hours did you put your MH on today?

I dont have canopy the fixture is about 10" above the water surface , I go with 1 hour only for rest of the week and 2 hours for next week, I move the fan power cord to the actinics power bar (9am - 10pm) probably ill keep it there for rest of summer .
