lighting for a 20g long tiank

[c_hemmerich]

i am about to buy my light for the 20g long tank that i am about to set up . i have decided to go with the coralife aqualite light fixture. what would be better a 1x 65W or a 2x65W? i have heard different people's opinions so i wanted to know some pro advice

I have a 29g long tank and I am using a 50/50 2X65W coralife aqualite light fixture for the day. At night I use a standard 24 inch light fixture with a 100% Actinic 03 blue light from coralife. My corals are doing great under these lights... I hope this helps
