After having a issue with my Aquatic life T5 HO building heat in my 55 gallon canopy tank averaging about 82.7. I tried to find a alternative to buying a chiller and it seemed to work very well and very cheap! It brought my temps down from 82.7 to 78.2. As shown in the pictures below.. (1) Purchased this 4" personal fan I found at Wal-Mart for $6. (2) Unscrewed the cover (3 screws) and removed the stand. (3) I had a 4" hole saw in my tool box already so don't know the price on a new one think $8-10. Cut my hole in the canopy. (4) Installed the fan with the three screws removed from fan cover and set it on my timer to run only when the lights come on. Total price for me was the cost of the fan $6 Quite & Cheap!
