Ii'm looking around for some better lights to put on my nano reef tank because i dont feel that i have enough on there. I have a sixteen gallon bowfront that is 17.5 inches tall and 20 inches acroos. Currently i have a 15 watt flourescent (actinic) and an 18 watt power compact on there. All i have for invertabrates are some mushrooms, some button polyps, and a BTA. I'm worried that he does not have enough light although he's looked pretty healthy for a few months. Any suggestions where i can find some decent lights?
