The temp in summer is kept between 80-82, in winter it is 78-80. I have a Copperband that keeps most of the Aptaisa out of the main tank, but one of my overflows is riddled with aptaisa and they trap food and detritus when it goes over the overflow. In the refugium I have a few different kinds of caulerpa, misc critters that I do not want in my main tank such as rock crabs, some weird hermits, a Blue Lobster (pretty cool) a Purple Lobster, Mysis shrimp, amphipods and copepods, live rock, a brittle star, and a few urchins that I do not think are reef safe. I also have a powerhead in their as well. I will post a few more pics of the equipment if I can find them in a little bit. Thanks for all of the kind words!
