So My T5HO's are heating my water considerably, My house is kept at 75 and the tank is running at 84 with the lights on.
I have a cheap wal-mart fan but its really not enough air flow.
I am looking at some fans that I can add to my canopy to make cross ventilation. I found some really cool ones with LED
's in them, but I dont know about CFM. How much air flow is my question.
I was thinking about maybe 3 of these across the front of my canopy blowing out the back.
