Hey,
I'm planning a 120 gallon (4'X2'X2') LPS/SPS tank with a 12" canopy housing an 8 T-5 retrofit lamp kit. A 2X4 will be attached to inside of the canopy so that the T-5 lamps will sit closer to the water. The back of the canopy is open. I'm undecided how I want to mount my canopy fans. What are your thoughts on the following options?
Option 1:
Mount 2 fans on the backside of the canopy pushing air inside and blowing across the T-5 bulb labels near the end caps.
Option 2:
Cut 2 holes in the top of the canopy for fans pulling air out. I understand that using fans to pull air out may reduce the life expectancy of the fans due to the saltwater.
Option 3:
Same as option 1 but cutting slits in the top of the canopy to allow hot air to escape.
I like the idea of mounting fans to the front of the canopy pushing air in but I prefer the front of the canopy to remain untouched.
I could combine options 1 & 2 but I'm trying to avoid using 4 fans.
Thanks for your thoughts and opinions.
