Exactly how much lighting would be required to keep an anemone in a 20 long? Is it overall volume of water or the depth of water the light has to penetrate? A 20 long is only 12" deep, the if I had 2" of substrate it would only be 10" of water the light would have to penetrate. Then of course the anemone isn't laying flat on the substrate either, if it was located half way up the tank or near the top the light would only be pentrating as little as 1" to 5" of water. Either way you look at it, it's less than 10" of water the light is penetrating to reach the anemone. I am looking into either a Current USA Nova T-5 24watt 10,000K and 24watt 460 actinic light fixture or the Corallife T-5 18watt 10,000k and 18watt 460 actinic light fixture. The Nova is 48watts total with 2 - 24" bulbs and the Corallife is 36watts total with 2 - 30" bulbs.
