Do It Yourself projects
I came across a Holmes Digital Twin Window Fan unit at the local Super Target in a clearance section. The sale price was less than $30 and I figured I could use it in my fish room. If it works then great, but if it didn't I didn't spend a ton of money and it claimed to save $$$ on my electric bill.
The unit is programmable to turn on automatically when a certain temperature is desired, or you can program a timer to turn on. Both fans are independently controllable to either exhaust
