I have a 18 gallon tall tank with live rock fish,shrimp and no coral. i have a mini compact fluorescent 20 watt. 2 bulbs one 10000k daylight the other actinic 03 blue. Im not sure what any of that means but i would like to know how long to cycle the light on and off and is this light sufficiet enough for live rock?
