just picked up an led lighting fixture from j&l to try out on a 30 gallon tank i 'm using to hold some of my fish while i rebuild my room for my 220.i will be picking up some aptasia infested coral for my berghia to clean up-so i can try the lights out on them-only 1 watt leds-but the tank is only12x10x48 so i'll see if i have any success
