Wow, thanks for the warm welcome. :) Well, please be patient as I will be learning the forum and my tank as I go, but I will take a stab at this. I have a 75 gallon, reef / fish, sitting over a cpr yr194, and under a 120 watt Illuminarium and reef bright strip. Although, I will "at some point soon" be changing back to a 30 gallon sump tank and an EV180-mag9 combo. Currently have around 120-140 pounds of live rock, will be reduced gradually as the tank stabilizes. For livestock... Ummmmmm... I have a lot of stuff. :/ Unfortunately, I am new still, and don't know all the names for everything. But as I learn to post pictures, I will also be learning more about the variety of life in my reef tank. Just try and be patient with me, I am a slow learner sometimes. That's also a secret. lol I am off to snap some photos.
