[quote=Enigma;745428]If it has 12 lights, I'm assuming you're got the 24-36" "Double Bright" fixture. That's only 0.6W per gallon (based on 20 gallons of water), which is really, really low. A longer light cycle will be a good idea, but your fixture is really going to limit what you can keep for corals.[/QUOTE

I'm not expert so I'm going for hardy corals that the requirements arnt all crazy...but sounds like im in order for a light upgrade here soon lol..thank you for the advice
