Those LEDs will probably be perfect for a fuge, I don't know much about LED lighting except that if you are looking for coral or macro growth you really need a PAR meter to see their effectiveness; unless of course the LED's are a well documented series like CREE. Thank you again for taking the ponies off of my hands. As soon as you left I pulled that 40gal and cleared out my Saltwater Laboratory haha. You'll have to let me know if they have babies again. I was never able to tell if the male was pregnant because the whole time that he wasn't he would swell his pouch to show off to the girl. Does he still chase her around as soon as the lights come on every morning? I will hit you up on Saturday for the Ulva. I have half a bucket's worth of really fine sand if you could use some? I've already washed it and it's not silt that doesn't settle, it settles pretty quickly, just fine grain like refugium mud. Anyways, I'm liking the setup you have going on.
