I agree with the angels. Wow did we just find a cheap light that grows corals. I did just read that most coral will be fine in 100 par but the color won't be there. HmmIt's been doing well with that $50 Aqua Knight light... so well, she's just going to get another one. I'm not planning on putting anything in here extremely light demanding. She's got an incredible hulk lepto glowing on the sand bed, the tank is just too big for one light. The Duncan colony was closed for a while, but after a small water change and a few quick puffs from the turkey baster, it's opening back up. Acans are still alive, and still closed up tight. I have a feeling the angels are nipping at them.
