[APD] Yet another good reason NOT to use so much light

If you use 1.5-2.5w/gal, you don't have nearly the same heating issues.
You use less electric, save on bulb and initial set up cost.
You have less algae issues and dosing upkeep.
You have slower and often better growth.
There is less demand on CO2/nuterients over all.
You don't need any more than perhaps 2-2.5 watts to grow any plant species,
if someone wants to claim that a plant needs more I'd like know which plant.

More light is not better.

I like the open top design I use for my PC lights, I can clip a fan on the
side to blow across the surface of the water for evaporative cooling.

Some chiller units for a tank this size are available for 160-300$ range
that will pull the temps down 10-25F.
