Your LB looks chubby, Brett, unless I'm not seeing right. Such characters. You may have some algae issues, but at least you have some good coralline growing on your Marco Rocks. I just have whitish patches where it is trying to grow, but just won't take. Are your corals growing as well as they were, and maintaining color?
I am glad you are keeping some interest going. I truly feel - having done it - that it's very difficult to start a tank with primarily dry rock. I feel that there is a "balance" that is missing that takes some good time establish itself. I am considering adding a little more live rock to my sump (after a serious search for trustworthy stuff), in the hope that more biological diversity will kick my growth into gear. And I, too, need to be a bit more diligent with water changes. 10% each week, perhaps.
I'm really glad you are back on the forum!
