Eclipse 3 20 gallon aquarium

[Randygus01]

I am removing the old light fixture and installing a kessil a80. Any body have suggestions
I have one a80
The tank is a 20 gallon tall and the light will Be in hood and only have about 4" clearance to water

Suggestions for what? an A80 on a 20 tall will only be adequate on a fish only tank, and if you have rocks really close to the surface maybe lower light soft corals.
