How much light will I need?

Probably better off to just run a small computer fan between the the fixture and the aquarium to push the heat away. This will allow to keep the full benifitof the light.

Worth a try, it might not be enough though.

Manny, If you already have the SE set up then use one of thoes, if you want to upgrade the punch then change the ballast out to a HQI ballast and run your SE off of it.. you will get more light than a DE. you could always build a hanging pendant to keep it about 8" off the water and run a small fan accross the top of the tank to remove heat.

This the way I keep my sumpless 90 from overheating with the 2 250 watt 10k's and 2 96 watt actinics beating down on it fron 6 inches away.

You'll get more evaporation (FREE COOLING!!!!!!!!), but topping up is cheap and easy to do.

I have decided to go with one of my 250watt SE lights. I will get a computer fan to blow over the tank to help keep the heat away. Thanks for your input.
